Full textAbstract:
Rabbits need species-specific care, in order to meet their health, welfare and behavioural needs. Preventative health care is imperative to help keep rabbits healthy. Advice needs to be given to owners on their rabbit's dietary requirements, and why hay and grass is imperative as the bulk of their diet. Vaccinations to help prevent myxomatosis and rabbit viral haemorrhagic disease (RVHD1 and RVHD2) should be advised for all rabbits, including house rabbits. Rabbits require adequate space and the companionship of another rabbit to live a good quality life. They should have access to an exercise area, and have the choice of where to spend their time, without the need to be picked up and moved from a hutch to a run. Many owners will look to veterinary nurses for current advice, and it is important that nurses feel confident in offering the most up-to-date information. At times, it may be that owners need to make changes to the way they care for their rabbits, and being confident in explaining why these need to be implemented, and the positive effects these will have on the rabbit's life, is vital.

Full textAbstract:
Some theorists argue that plant and animal species introduced to new localities should be controlled only if they cause damage and not because they originated in another country; this warrants greater acceptance of introduced species as participants in new ecological associations in a rapidly changing world. To evaluate this concept and its relevance in setting directions for rabbit control in Australia, this idea is not only reviewed against information on the rabbit’s impact in Australian ecosystems but also against management policies, industrial drivers and social expectations. It is concluded that wild rabbits hold many natural Australian ecosystems in a degraded state and any beneficial ecological roles rabbits provide are small by comparison. Furthermore, rabbits can be controlled adequately to initiate ecosystem restoration. The idea that introduced rabbits should be more readily accepted as participants in new ecosystems is strongly counter-argued. Rabbits are not harmless passengers in Australian ecosystems and, to achieve ecosystem recovery, a high level of rabbit control is necessary.

Rabbits are mammals from the family Leporidae (green plant eaters) which can be found in many parts of the earth. Rabbits are very susceptible to temperature changes. Temperature greatly affects the rabbit's body metabolism. The temperature ideal for rabbits is in the range of 60 – 650F or equal to 15.5 - 18.30C temperature is known as "comfort zone" for rabbits. The level of heat stress in rabbits is very high in the tropics thereby reducing rabbit productivity. With a system that researchers can make it easier to determine the suitable place to serve as a rabbit habitat with the Internet of Things system network, and reduce the failure rate in keeping rabbits as well as the implementation of the node-ed as a platform to display the results of the calculation method of the decision.
The system is applied using the SAW (Simple Additive Weight) ranking method or commonly called this weighted method by using three parameters including temperature; humidity; light. However, the data must go through a calculation that generates a value of each location then normalize to get a decision by the sum of the multiplication of normalization with weights.
Implementation Methods of SAW (Simple Additive weighting) as Decision Support Habitat For Rabbits Recommendation Based IoT (Internet Of Things) has been successfully applied. So that it can rank rabbit habitat locations based on parameters of temperature, humidity, light. However, although the system is built based on IOT but has not publicly accessible or still based on the localhost.

Full textAbstract:
The aim of this work was to propose a model of free-range raising for rabbit able to maximize the animal welfare and at the same time the productive performances through the use of mirrors. A total of 81 rabbits were allocated into free-range areas and divided into three groups (nine replicates per group): in the first group (face to face, F2F), the rabbits of each replicate could see each other. In the second group (blind) each replicate was isolated from the others; in the third group (mirrors), the replicates were divided as for the Blind group but two mirrors were placed in a corner of the perimeter. The blind group rabbits showed the lowest final weight (p < 0.05), while rabbits from the mirrors groups showed the best FCR and net dressing out values. The blind group showed the highest production of total short chain fatty acids, acetate (p < 0.05) and propionate (p < 0.01). The F2F rabbits showed higher levels of creatine phosphokinase and lactate dehydrogenase and lower values of blood glucose than those of the other groups, due to the higher locomotion activity. The use of mirrors can improve rabbit’s growth performance and carcass traits by lowering the rabbit’s locomotion activity in comparison to the other tested systems.

Full textAbstract:
This study discusses the symbolism of the rabbit statue on the base of a celadon incense burner with an openwork auspicious-character design lid in the National Museum of Korea. Chapter II analyzes the overall design of the incense burner, pointing out that although the rabbit statue is small in size, it is a three-dimensional figure with detailed carving of each part of the body and inlaid techniques used to express the eyes, making it an important component that embodies artistry beyond a simple base. Chapter III explores the spectrum of perceptions of the rabbit by examining rabbit sculptures from before the Goryeo period. As a symbol of fertility and longevity, thought to be a guide to the quick passage of the souls of the dead to the afterlife, rabbits were attached to funerary urns in the Silla period. They were depicted as moon symbols in Goguryeo tomb paintings and Unified Silla roof-end tiles. In Unified Silla, rabbits were also carved into royal tombs as members of the Twelve Great Deities to show the despotic kingship of the kings guarding the tomb, or were majestically displayed in stupas to represent the authority of Bhaisajyaguru. In Chapter IV, the meaning of the three rabbits supporting the incense burner was derived from three aspects. First, the intention of the rabbit's representation on the incense was inferred from the similarities between the rabbit's self-sacrifice and the offering of incense in The Jataka Tales of the Rabbit's Original Life (Sasa Jataka), which is to burn oneself and offer it to the gods. Since the rabbit was Buddha in the previous life, the life in which he practiced the great act of selflessness, it is believed that the rabbit was chosen to stand alone on the base of the incense burner, even though it does not symbolize absolute physical power. Through this carving of the rabbit, it can be seen that the 12th-century Goryeo people understood the offering of incense and the act of self-sacrifice in the same context. Second, the appearance of rabbits in historical texts and geographical journals from the Three Kingdoms and Goryeo periods was examined. In doing so, the chapter describes who recognized rabbits as auspicious animals in addition to being a symbol in Buddhism. Third, it discusses the internationalization of Goryeo culture, which is reflected in the sculpture of the atlas that supports the top. It is interpreted that the incense burner represents the cosmopolitanism of Goryeo culture because the rabbit statue on the incense burner was arranged in a form similar to the atlas statues popular in ancient Greece, Persia, and India and spread along the Silk Road.

Full textAbstract:
Rabbit breeding is a special branch of animal husbandry characterized by high fertility and growth intensity. The main way of intensification of rabbit farming involves such selection measures that adapt rabbit populations of keeping in industrial conditions, ensure high reproductive properties of female rabbits, preservation of rabbits in nests, high growth rate, fattening and meat qualities of animals. The research was conducted on the basis of the experimental rabbit farm of the Cherkasy Research Station of Bioresources of the National Academy of Sciences on the population of female chinchilla (Chinchilla) rabbits and males of the Gray giant rabbit (Gray giant rabbit), New Zealand white rabbit (New Zealand white rabbit) and young rabbits obtained from these three combinations. As the result of the conducted research, it was found that under the conditions of intensive production of rabbit meat, the reproductive qualities of female chinchilla rabbits in combination with males of the Gray giant and New Zealand white rabbits breeds increase, namely: high fertility – on 1.8–5.2 %; milk yield – on 1.8–7.4 %. The weight of the nest at weaning was probably (P < 0.001) higher in female rabbits of the combination Chinchilla x New Zealand white rabbit and was 5.29 ± 0.13 kg, which is 869 g more than the purebred peers of the chinchilla breed and 380 g more than the combination Chinchilla x Great giant rabbit. The best indicators of fattening and meat productivity were found in young rabbits of 1/2Chinchilla 1/2Gray giant rabbit and 1/2Chinchilla 1/2New Zealand white rabbit origin. The fattening indicators of the rabbits of these groups compared to the rabbits of the control group accordingly increased: live weight at 90 days of age – on 4.0 and 3.8 % (Р < 0.05); average daily increases – on 4.7 and 5.4 % (Р < 0.05; Р < 0.01); waist width – on 5.6 and 8.7 % (Р < 0.01). The research also revealed that the group of young rabbits 1/2Chinchilla 1/2New Zealand white rabbit by origin had a higher slaughter yield and the indicators of which exceeded and rabbits of the second group ( 1/2Chinchilla 1/2Gray giant rabbit on 3.6% and the first (Chinchilla) – on 4.1 %, and the expenses of feed per 1 kg of increase by group was 3.85 accordingly; 3.75; 3.7 kg. Crossbred rabbits 1/2Chinchilla 1/2New Zealand white rabbit and 1/2Chinchilla 1/2Gray giant rabbit according to this indicator prevailed over purebred peers (Chinchilla) on 2.6 and 3.9 %, accordingly.

Full textAbstract:
Is it possible to reduce feeding costs in rabbit meat production without compromising rabbit health and productive yield? The study tested four feeding strategies: Control group (CC) fed exclusively with concentrate feed; group CT supplemented with whole carrot; group OH supplemented with oat hay; and Group CO supplemented with oat hay and whole carrot. Each feeding strategy was tested in 20 rabbits, randomly allocated in five cages with four rabbits each. The average daily weight gain (ADG), feed conversion ratio (FCR), and the amount of concentrated feed consumed daily were estimated in all experimental groups. Group CC displayed the best ADG (37.1 g/rabbit/day), carrot had no significant influence on ADG (34.2 g/rabbit/day), but oat hay had a negative impact (p < 0.05), either used alone or in combination with carrot (33.0 and 32.6 g/rabbit/day, respectively). Supplementation with carrot, oat hay, or both increased the FCR (p < 0.001). Nevertheless, there were no significant differences in final live weight or carcass weight between the rabbits in the different experimental groups. In conclusion, supplementation with oat hay, carrot, or both can be a valid approach to reducing production costs by decreasing concentrate feed without affecting rabbit’s health and meat yield. The combined supplementation with oat hay and carrot proved to be the best option in reducing the amount of concentrate feed ingested by rabbits (less than 1107 g/animal), but at current market values, supplementation exclusively with oat hay was the less expensive feeding strategy (less 14% than fed exclusively with concentrate feeding).

Full textAbstract:
Improving the housing conditions of individually caged laboratory rabbits using environmental enrichment devices is a source of concern in the scientific community and is encouraged in the guidelines of the local and international laboratory animal associations and national regulations. In this report, we inform on the results of an investigation whose aim was to evaluate the use of a commercially available shelter as an enrichment device for six individually caged rabbits (mean body weight 2.5 Kg) during their resting period. After an acclimatization period of five days in an animal room, a commercially available enrichment device, the Rabbit Hut (BioServ, New Jersey, USA), was introduced into every cage. After a 3-day familiarization period, the interactions of the rabbits with the device were video recorded for 12 hours during the light phase (06:00 – 18:00) on five consecutive days. Each rabbit’s interaction with the device was monitored and analyzed from the video recordings. We found that the rabbits used the enrichment device in different ways, which included passing through the device, staying under the device, gnawing the device, pulling and dragging the device using their teeth, and playing with the device. We also found that the rabbits mainly interacted with the device during the first two hours (06:00 – 08:00) and last four hours (14:00 – 18:00) of each 12-hour observation period of the 5-day investigation. Although the Rabbit Hut is marketed as an environmental enrichment item that could be used as a shelter for individually caged laboratory rabbits, our analysis of the interactions of individually caged laboratory rabbits with the device has generated new questions about the usefulness of the device and its benefit for the rabbits. However, further investigation is needed to clarify whether some of the expressed interactions indicate curiosity, interest or frustration with the item.

Full textAbstract:
Although there have been a number of studies that have examined the effects of rabbits on pasture, the relationship between rabbit density and pasture degradation caused by rabbits has never been quantified. An experiment was conducted at Cowra, New South Wales, from October 1984 to October 1987, to determine the impact various densities of rabbits have on pasture composition, indices of pasture biomass and ground cover. Using plots set stocked with the equivalent of 8 sheep/ha (the district average) and 4 densities of rabbits as treatments, 0,�24, 48 and 72 rabbits/ha, the consequences of rabbit grazing were investigated.Pasture composition changed with season, year and rabbit density. Cumulative effects were also evident. Rabbits severely depleted improved pastures of legumes (subterranean clover particularly), with grass cover increasing proportionate to rabbit density. In the final year of the experiment, the rabbit-free treatment had 31% legumes and 25.2% grasses, whereas the highest rabbit density treatment had 6.2% legumes and 47.4% grasses. Indices of pasture biomass were highest in the zero rabbits/ha treatment and lowest in the 72 rabbits/ha treatment. More bare soil was exposed in the highest rabbit density treatment. Once seasonal and year effects were accounted for, the relationship between rabbit density and percentage damage was positive.

Full textAbstract:
The European wild rabbit (Oryctolagus cuniculus) plays an important ecological role in the ecosystems of the Iberian Peninsula. Recently, rabbit populations have drastically reduced, so the species is now considered endangered. However, in some places, this animal is considered a pest. This is the conservation paradox of the 21st century: the wild rabbit is both an invasive alien and an endangered native species. The authors of this review aimed to understand the keys to the adaptive success of European rabbits, addressing all aspects of their biology in order to provide the keys to the ecological management of this species. Aspects including nutrition, genetics, immunity interactions with the environment, behaviour, and conflict with human activities were reviewed. Ultimately, rabbits are resilient and adaptable. The main adaptations that explain the rabbit’s adaptive success are its nutrition (wide adaptation to food and good nutritional use of caecotrophy), immune system (powerful and developed), and other aspects related to genetics and behaviour. Rabbits’ relationship with humans has led them to colonise other places where they have become pests. Despite these adaptations, populations in native places have been drastically reduced in recent years. Since it serves as a bastion of the Mediterranean ecosystem, a specific conservation program for this species must be carried out. Therefore, a study of the rabbit’s response to diseases and nutrition (especially protein), as well as the interaction between them, is of special interest.

Full textAbstract:
Background.In this study, we examined whether UV-visible and fluorescence spectroscopy techniques detect the progression of atherosclerosis in serum of rabbits fed on high-cholesterol diet (HCD) and HCD supplemented with zinc (HCD + Zn) compared with the control.Methods.The control rabbits group was fed on 100 g/day of normal diet. The HCD group was fed on Purina Certified Rabbit Chow supplemented with 1.0% cholesterol plus 1.0% olive oil (100 g/day) for the same period. The HCD + Zn group was fed on normal Purina Certified Rabbit Chow plus 1.0% cholesterol and 1.0% olive oil supplemented with 470 ppm Zn for the same feeding period. UV-visible and fluorescence spectroscopy and biochemistry in Rabbit’s blood serum and blood hematology were measured in Rabbit’s blood.Results.We found that the fluorescent peak of HCD shifted toward UV-visible wavelength compared with the control using fluorescent excitation of serum at 192 nm. In addition, they showed that supplementation of zinc (350 ppm) restored the fluorescent peak closely to the control. By using UV-visible spectroscopy approach, we found that the peak absorbance of HCD (about 280 nm) was higher than that of control and that zinc supplementation seemed to decrease the absorbance.Conclusions.This study demonstrates that ultraviolet-visible and fluorescence spectroscopy techniques can be applied as noninvasive techniques on a sample blood serum for diagnosing or detecting the progression of atherosclerosis. The Zn supplementation to rabbits fed on HCD delays or retards the progression of atherosclerosis. Inducing anemia in rabbits fed on HCD delays the progression of atherosclerosis.

For the prospects of the rabbit breeding of present time optimal direction of development are individual and farmer economies, with the middle population of doe-rabbit. For the profitable conduct of the rabbit breeding except general principles of maintenance and growing, it is expedient to take into account the pedigree features of rabbits. Most distribution for the rabbit breeders of our country meat and hide of breed got: grey and white giants, butterfly, silvery, less popularity is used by the meat breeds of rabbits: New Zealand white and Californian.
Main advantage of the rabbit breeding are an economy of areas and absence of capital apartments for growing of population of rabbits, in the modern rabbit breeding the systems of maintenance of rabbits are used in cages – outside, with the partial or complete process of mechanization: feeding and give to drink, moving away of wastes. At cellular maintenance of rabbits the most rational organization of works is provided on a supervision and reproduction. Cellular maintenance of rabbits gives an opportunity to carry out and control all processes and effectively to conduct veterinary and prophylactic measures. The table of contents of rabbits in cages provides a receipt from them of high-quality selfish products and carcass of kind fattened. For growing of different breeds of rabbits optimal economic indicators are the breeding of 30 female rabbits and more, at such population recoupment presents three years.
The efficiency of management and high profitability of organic rabbit farms is ensured thanks to small capital investments in equipment and cages, early maturity and multi-fertility of rabbits, intensive growth of rabbits and rapid change of generations, obtaining products of high quality and quantity in a short time. The use of modern improved cage systems, high-quality feed and balanced rations for sexual age groups of rabbits allows to optimize the operating costs of the rabbit farm, and properly adjusted logistics of rabbit breeding products ensures constant profit at optimal profitability.

Much research, time and money have been invested in the control of rabbits in Australia, yet the relationship between rabbit density and livestock production losses has not been quantified. We experimentally investigated the variations in sheep production parameters caused by 4 densities of rabbits, 0, 24, 48 and 72 rabbits/ha. Medium to strong wool merino wethers were run at a constant stocking rate in replicated plots with rabbits at 4� different densities. Sheep liveweight and body condition and wool production variables were measured over 3�years. Low to medium densities of rabbits were not found to reduce liveweights of wethers, whereas wethers run with the high density of rabbits were significantly lighter. The presence of rabbits reduced the body condition of sympatric sheep with the lowest body condition recorded at the high rabbit density. Mean greasy fleece weights, wool yields and clean-fleece weights were significantly different between densities of rabbits. Wethers run with the high rabbit density grew less wool than the wethers run with the other 3 densities of rabbits. The cumulative gross return per ha from wool production was highest for the medium rabbit density and lowest at high rabbit density. At the conclusion of this short-term experiment, the presence of some rabbits enhanced returns from wool production because of lower fibre diameter and comparable clean-fleece weights of fleeces grown at low and medium rabbit densities. These production characteristics might have been caused by synergistic effects on pasture growth or a sheep stocking rate that was too conservative for the prevailing seasonal conditions. At high rabbit density, competition for pasture between rabbits and sheep overrode possible synergistic and understocking effects. The economic implications of the presence of rabbits on merino sheep production are discussed.

Rabbits are meat-producing livestock with high productivity. Rabbit meat has high nutritional content and is good for health. The DKI Jakarta Government through the Center for Animal Health and Livestock Services (Pusyankeswannak) has opened the Bambu Apus Livestock Park. This research was conducted to determine the productivity of bambu apus rabbit carcasses as broiler rabbits to support urban farming programs in DKI Jakarta. Ten of bambu apus rabbits (five males and five females), ten of new zealand white rabbits (eight males and two females) and 17 rexsi grinak rabbits (eight males and nine females) were used. The body weights of the rabbits ranged from 2000 to 3000 g per head. This research has obtained Ethical Clearance (Balitbangtan/Center for Animal Husbandry Research BRIN/NRm/01/2022). Rabbits were slaughtered according to Islamic Syar’i and the carcass were cutting according to the commercial cut. A completely randomized design with a 3 x 2 factorial pattern (sex and type of rabbit) was used with carcass productivity and meat physical properties as variables. Bambu apus rabbits have good carcass productivity (Carcass Percentage, Meat Bone Ratio), meat on commercial cuts (Loin and Hindleg) and carcass quality (pH, tenderness, Water Holding Capacity and cooking losses) which were the same as new zealand white rabbits and rexsi agrinak rabbits as the broiler rabbit. Bambu apus rabbits have good carcass production and carcass meat quality so they have the potential to be developed into broiler rabbits in support of urban farming programs.

Full textAbstract:
The rabbit breeding industry in Ukraine is an important element of animal husbandry, most of the rabbits are in private households. In the absence of systematic veterinary care, accurate postmortem diagnosis of the causes of death of rabbits in households is important. Rabbit eimeriosis is widespread in Ukraine and with mixed intestinal and hepatic forms of eimeriosis against the background of unsatisfactory feeding and maintenance in young rabbits can cause death. Viral hemorrhagic disease of rabbits is also common in Ukraine and causes the death of rabbits of all ages. The aim was to study the pathomorphological changes in eimeria and viral hemorrhagic disease of rabbits and the use of other methods to confirm the diagnosis. The article presents the results of pathological, coprological and microbiological diagnosis of rabbit eimeriosis. Polymerase chain reaction was used to confirm the diagnosis of viral hemorrhagic disease of rabbits with the simultaneous establishment of the genotype of the pathogen. The effectiveness of the use of additional methods of postmortem diagnosis of eimeria (coprological, microscopic) and viral hemorrhagic disease of rabbits (polymerase chain reaction) was established. In rabbits that died from rabbit hemorrhagic disease the infection was caused by the virus of the first type. Key words: pathological and anatomical diagnosis, coproscopy, PCR, liver damage.

Full textAbstract:
A seven week feeding trial was conducted to evaluate the growth performance characteristics and economics of production of 15 unsexed weaner rabbits fed varying levels of Sundried false yam (Icacina tricantha) meal. Five treatments diets were formulated with diet 1 containing 100% maize as control, while in diet 2, 3, 4 and 5 Sundried false yam meal replaced the percentage proportion of maize in diet 1 at 25, 50, 75 and 100% inclusion level respectively. Rabbits were randomly assigned to the five treatment diets in a complete randomized designed (CRD) with three replicates of one rabbits each. Performance characteristics revealed that final live weight and weekly feed intake were significantly (P<0.05) influenced with highest value (2.12kg/rabbit and 407.33g/rabbit) recorded from rabbits fed 0% SDFYM comparable to (1.98kg/rabbit and 323.33g/rabbits) recorded in those fed 50% SDFYM. Avearage weekly weight gain was also significantly (P<0.05) influenced with highest value (197.00g/rabbit) from those fed 50% SDFYM. Feed conversion was lowest and best (1.28) from rabbits fed 25% SDFYM. Mortality rate was lowest (3.43%) in rabbits fed 50% SDFYM. Cost and return analysis revealed that total cost of feed consumed was least (378.24 N /rabbits) from those fed 50% SDFYM and highest in control, cost of feed per kg weight gain and total cost of production were lowest (30.50 and 2178.24 N /rabbits) from the rabbits that ate 75% SDFYM and highest in control. Income and net profit were highest (5000 and 1763.36 N /rabbits). It is concluded from this study that Sundried false yam meal is a valuable substitution for maize up to 50% in rabbit diets without any adverse effects on the performance characteristics and economic returns of rabbits.

AbstractThe aim of our study was to analyze the anatomy and surgical approach of the rabbit brachial plexus. The research included 18 rabbits. The rabbit seems to be a good experimental model for spinal nerves injury, especially for the C5 and C6 segments. The anatomical structure of the rabbit’s brachial plexus is similar to the human brachial plexus. The structure of the rabbit C5 and C6 segments is analogous to the human structure. The spinal nerves of the C5 and C6 segments in the rabbit are wide and long enough for microsurgical procedures

Full textAbstract:
Novel genotypes of hepatitis E virus (HEV), i.e., HEV-5, HEV-7, and HEV-8, have been identified in wild boar, dromedary camels, and Bactrian camels, respectively, and they transmit to cynomolgus monkeys in a trans-species manner, raising the potential for zoonotic infection. Rabbits are the natural reservoir for rabbit HEV, but they are also susceptible to HEV-3 and HEV-4. It has been unknown whether rabbits are susceptible to HEV-5, HEV-7, and HEV-8. To investigate the infectivity of novel HEVs in rabbits and to assess whether rabbits are appropriate animal models for these HEVs, we inoculated Japanese white rabbits with HEV-5, HEV-7, and HEV-8, respectively. We observed that viral RNA was present in the fecal specimens of the HEV-8-inoculated rabbits and anti-HEV IgG antibodies were present in its sera, although anti-HEV IgM was undetectable and no significant elevation of ALT was observed. These results indicated that HEV-8 crossed species and infected the rabbits. No evidence for replication was observed in HEV-5 and HEV-7, suggesting that rabbits are not susceptible to these genotypes. The antibodies elicited in the HEV-8-infected rabbits did not protect them from the rabbit HEV challenge, suggesting that the antigenicity differs between HEV-8 and rabbit HEV. Antigenic analyses demonstrated that anti-HEV-8 antibodies reacted more strongly with homologous HEV-8 virus-like particles (VLPs) compared to heterologous rabbit HEV VLPs, but anti-rabbit HEV antibody had similar reactivity to the VLPs of rabbit HEV and HEV-8, suggesting that HEV-8 lacks some epitope(s) that exist in rabbit HEV and induced the neutralizing antibodies against rabbit HEV.

In clinical examination of rabbits, the temperature is usually recorded with a digital thermometer introduced rectally, an invasive procedure that could cause handling stress. The aim of this study was to assess body temperature using infrared thermography (IRT) in four areas of the rabbit’s anatomy: eye (ETT), outer ear (OETT), inner ear (IETT) and nose (NTT), and then validate it as an alternative measure to rectal temperature (RT) assessed with a conventional thermometer. Temperature samples were taken twice a week from 48 weaned rabbits of Spanish Common Rabbit breed during a 38-d fattening period. The factors considered were: doe from which the rabbits came (8 does), weeks of fattening period (4 to 5 wk), batch (3 periods of the year: April-May, June-July and January-February) and group size (cages with 1 to 7 rabbits). On average, the results were an RT of 38.48±0.02 °C; ETT of 37.31±0.05 °C; OETT of 29.09±0.26°C; IETT of 30.53±0.251 °C, and NTT of 33.29±0.11 °C (mean±se).

<p>This study aimed to conduct a preliminary survey to investigate basic ownership factors, frequency of microchipping and insurance and views of pet rabbit owners n these areas and general rabbit management. More specifically, we aimed to investigate whether owners possess insurance, whether their rabbits are microchipped, and owners’ views on the recommendations relating to rabbits (e.g. recommended enclosure sizes) and the law. A questionnaire was designed and promulgated through social media sites and rabbit forums. A total of 1183 responses were received. Just over 29% of respondents sourced their rabbits through rescue centres. 73.9% (867/1174) of owners stated that they had no pet insurance for their rabbits. Concerning microchips, 78.3% (919/1173) of rabbits were not microchipped, while 21.7% (254/1173) were. This preliminary study found that the majority of individuals are of the opinion that the relevant law is insufficiently publicised. A more detailed study would be beneficial to investigate and provide further insight into rabbit owners and their views and concerns for rabbits. The results of such a study could help formulate rabbit-related information and guidelines which in turn could have a direct impact on pet rabbit welfare.</p>

Full textAbstract:
Context Some ecologists argue that nesting success and abundance of wedge-tailed eagles (Aquila audax) are strongly linked to the abundance of introduced wild rabbits (Oryctolagus cuniculus). Consequently, concerns were expressed about eagle population viability when the biological control agent rabbit haemorrhagic disease virus (RHDV) heavily reduced rabbit numbers. However, observations following the spread of rabbit haemorrhagic disease (RHD) in Australia and Spain (where Aquila adalberti is an equivalent of A. audax) question this assertion. Eagle numbers did not fall even though rabbits declined regionally by up to 90% in both countries. Aims To reconsider the assumption of a strong link between rabbit abundance and wedge-tailed eagle breeding and population maintenance. Dispelling misconceptions, if any, about the eagles’ dependence on rabbits would benefit the future management of both eagles and rabbits. Methods We reviewed the literature associated with claims that eagles were heavily dependent on rabbits and asked whether these views could be substantiated given the lack of changes in eagle abundance following the spread of RHD. Data on eagle egg-clutch size and nesting success were also reviewed. Conclusions There is little evidence that eagles depend heavily on rabbits as prey. Instead, as rabbits decline, more kangaroos, reptiles and birds are eaten, partly because more native prey becomes available. Eagles have a high proportion of rabbits in their diets mainly where degradation of natural ecosystems, including that caused by rabbits, results in native prey being rare or unavailable. There has been minimal variation in average clutch size following major perturbations in rabbit population size. Implications Rather than perpetuating the idea that high populations of rabbits are needed for wedge-tailed eagle conservation, resources would be better re-directed into understanding continental-scale eagle population dynamics. This would provide a more rational framework to assist decisions on future biological control agents for rabbits.

Full textAbstract:
Mortality of radio-tagged adult rabbits (Oryctolagus cuniculus) (n = 274) was monitored for one year in central-western New South Wales. The overall mortality rate was 82%. Predation was the most important and consistent cause of adult rabbit mortality, accounting for 44% of the total number of rabbits, followed by Rabbit Haemorrhagic Disease (RHD) (16%), myxomatosis (9%), unknown causes (9%), and enteritis/peritonitis (2%). Foxes were the most important predators, accounting for 28% of radio-tagged rabbits. Medium to large birds of prey were less important, accounting for 10%, followed by cats, which were responsible for 6% of the deaths of radio-collared rabbits. Myxomatosis outbreaks occurred in February/March and November–January. An RHD outbreak occurred during July, with 40% of the adult rabbit population being killed. The number of male and female radio-collared adult rabbits killed by each mortality agent throughout the year was similar. The proportions of warren-dwelling rabbits and surface-dwelling, solitary rabbits killed were similar overall; however, a significantly higher number of warren-dwelling rabbits were killed by myxomatosis and a significantly higher number of surface-dwelling rabbits were killed by RHD.

Blood parameters are an important index to assess the body homeostasis in mammals. Here, the effect of pesticide (imidacloprid) contaminated feed exposure on the haematological parameters of adult rabbits (n=15) was studied. Pesticides (Imidacloprid, Bildor® 0.5ml (100mg)/L water spray on vegetables and green grass) exposed feed fed to rabbits with wash (washed feed rabbit) or without a wash (not washed feed rabbit) in the once-daily morning for every alternative day up to 15 days. Control rabbits have received a standard diet (fresh vegetables and green grass). The blood cell analysis showed that the total erythrocyte count, packed cell volume, and haemoglobin values were not changed significantly in pesticide exposed rabbit. For differential leukocyte count, the percentage of neutrophil and eosinophil was significantly decreased in the pesticide-exposed rabbit as compared to the control rabbit. The lymphocyte percentage was increased significantly in pesticide-exposed rabbits compared to control rabbits. Interestingly, the number of lymphocytes was significantly increased in not washed feed rabbits compared to wash feed rabbits. The results of the present study suggest that residue of agriculturally used pesticides may affect the body homeostasis of animals.

Mycobacterium avium subspecies paratuberculosis, the organism responsible for paratuberculosis in cattle and sheep has been found in wild rabbits (Oryctolagus cuniculus) in the east of Scotland. Few studies have investigated either the level of faecal contamination by rabbits on farms, or the potential infectivity of rabbit excreta. The rate of rabbit faecal contamination deposited and the numbers encountered were estimated for 21 fields on 4 farms with a paratuberculosis problem. 7357±2571 S.E.M. rabbit faecal pellets were deposited per hectare per day and up to 81000 pellets/ha (‘standing crop’) were encountered in October/November 1998. Where access to rabbits was restricted, the standing crop of faeces encountered fell to 22000 pellets/ha.The prevalence of infection with M. a. paratuberculosis was assessed for 83 rabbits from the four farms. M. a. paratuberculosis was isolated from rabbits on all farms with an overall prevalence of 17%. Out of 17 rabbits from which urine was available, M. a. paratuberculosis was isolated from two – the first reported isolation from urine in wild rabbits. The mean number of colony-forming units per gram of infected rabbit faeces was 7·6×105±5·2×105.A relative estimate of the input of M. a. paratuberculosis onto pasture, at the stocking levels found on the four farms, showed that sheep and cattle potentially contributed 4 and 125 times more organisms/ha per day respectively than rabbits. However, rabbits could still contribute millions of M. a. paratuberculosis organisms per ha per day. Existing rabbit control measures on farms may be inadequate in reducing the risk of transmission to livestock.

Rabbit meat can contribute to the sustainable development goal (SDG) for food and nutrition security and poverty alleviation since there is an upsurged interest in rabbit farming in the country. The study aimed at documenting the management practices of the emerging rabbit producers in terms of housing, feeding, breeding, and health and disease management. The study uses qualitative-descriptive research, which utilized in-depth semi-structured interviews with 33 rabbit producers, a snowball sampling technique was used to identify the respondent. Findings revealed that in terms of housing practices the majority of the respondents use cages of different sizes depending on the rabbit’s growth, mostly made of galvanized wire but some use local materials such as bamboo and used wood. For feeding practices, the majority use a combination of rabbit pellets & forages. While for breeding practices, they practice reproduction and care management, and weaning of kits. For health and disease management, the most common disease of the rabbit was diarrhea and skin disease, experienced by mostly young rabbits to adults. Respondent has knowledge in curing diseases of rabbits and can identify symptoms. With the increasing rabbit production, management practices currently utilized by rabbit farmers have an impact on the rabbit performance, and it needs to determine and provide information to make the venture profitable.

Full textAbstract:
The fever responses of rats and rabbits were compared in detail using a single common source of semipurified endogenous pyrogen prepared from human monocytes. The characteristics and dynamics of the fever-response curves for each species were examined and their dose-response curves were determined and compared. The fevers displayed by rats were qualitatively similar to those of rabbits, but, typically, they developed and terminated more rapidly than those of rabbits. Rabbits were much more sensitive to the endogenous pyrogen than rats. The threshold dose of pyrogen required to elicit a fever was 5 times lower in the rabbit, and the slope of the rabbit's dose-response curve was 1.5 times steeper than that of the rat. The maximum fevers attainable in rabbits were approximately twice those attainable in rats. It was also shown that the more rapid febrile responses of the rat were not due to the 10-fold smaller mass of the rat; instead, we proposed that this difference was more likely due to a closer diffusional proximity of the pyrogen receptor sites to the circulation in rats. The lower sensitivity of the rat to endogenous pyrogen was attributed to a relative insensitivity of the pyrogen receptor sites in rats in the translation of the endogenous pyrogen stimulus into fever.

China officially promulgated the announcement of banning the use of antibiotics in the animal industry in 2020. However, the prohibition of antibiotics in the animal industry would reduce the feed conversion rate and increase the mortality of animals. In order to obtain information about the pathogenesis and host immune response of rabbits with diarrhea after being fed an antibiotic-free diet, we first analyzed the intestinal tissue sections of rabbits. Secondly, the gene expression differences of rabbit intestinal segments were analyzed by high-throughput sequencing. Our analysis identified 168, 593, 2069, 334, 321, and 1423 DEGs in the comparison groups S_Z (the duodenum of healthy rabbits) vs. S_B (diarrhea in the duodenum of rabbits), K_Z (healthy rabbit jejunum) vs. K_B (rabbits with diarrhea in the jejunum), H_Z (healthy rabbit ileum) vs. H_B (rabbits with diarrhea in the ileum), M_Z (healthy cecum of rabbits) vs. M_B (rabbits with diarrhea in the cecum), J_Z (healthy rabbit colon) vs. J_B (colon of rabbits with diarrhea), and Z_Z (healthy rabbit rectum) vs. Z_B (rectum of rabbits with diarrhea), respectively. The reproducibility and repeatability of the results were validated by RT-qPCR. Enrichment analyses of GO annotations and KEGG pathways revealed the host DEGs that are potentially related to acute inflammation, stress response, tissue dehydration, adaptive immune response, protein binding, activation of related enzymes, migration of immune cells, and so on. In this descriptive study, our findings revealed the changes in the host transcriptome expression profile after feeding an antibiotic-free diet and suggested that feeding an antibiotic-free diet alters the host’s metabolic network and the expression of antiviral proteins, which provides a theoretical basis for further study on the immune response of animals fed an antibiotic-free diet.

Domestic rabbits (Oryctolagus cuniculus) are the fourth most common species admitted to the British Columbia Society for the Prevention of Cruelty to Animals (BC SPCA) shelter system. However, shelter data analysis has largely focused on cats and dogs and little is known about the population dynamics of rabbits in shelters. We analyzed five years of rabbit records (n = 1567) at the BC SPCA to identify trends in intake and predictors of length of stay (LOS) of rabbits. The majority of rabbits were surrendered by their owners (40.2%), with most rabbits being surrendered for human-related reasons (96.9%). Overall, rabbit intakes decreased over the study period. When analyzing by month of intake, rabbit intakes were found to be the highest in May. Most rabbits in our data were adults (46.7%), non-brachycephalic (66.7%), erect-eared (82.5%), short-furred (76.2%), and subsequently adopted (80.3%). The median LOS of rabbits was 29 days, highlighting the pressing need to improve their time to adoption. A linear model was constructed to identify predictors of LOS of adopted rabbits (n = 1203) and revealed that intake year, intake month, source of intake, age, cephalic type, and breed size significantly predicted time to adoption for rabbits (F(37, 1165) = 7.95, p < 2.2e-16, adjusted R2 = 0.18). These findings help characterize shelter population dynamics for rabbits, shed light on the challenges associated with unwanted rabbits, and offer a foundation for animal shelters to design programs and marketing strategies tailored to reduce LOS of rabbits with particular characteristics. Shelter rabbits represent an understudied population and our study highlights the importance of further research in companion rabbits.

Fifty - four weaned 4-5 weeks old crosses of New Zealand white x Chinchilla male rabbits were utilized to evaluate the effect of feeding sugarcane peel meal-based diets supplemented with quantum blue® on the growth performance parameters (initial weight, final weight, weight gain, feed intake, FCR and feed cost per weight gain) and nutrient digestibility by weaner rabbits. Six diets were formulated to be iso-nitrogenous (18% crude protein) and isocaloric (2700kcal/kg, ME) with two levels of inclusion of sugarcane peel meal (SCPM) (low and high) and three levels of enzyme supplementation (0, 150 and 250 PPM) giving a 2x3 factorial arrangement fitted into Completely Randomized Design. The rabbits were weighed and allotted to the treatments at the rate of 3 rabbits per replicate and each treatment was replicated 3 times. Feeds were weighed and served to the animals individually and water was provided ad-libitum. Growth parameters and nutrient digestibility data were generated and evaluated. The results of the effect of enzyme on growth performance of weaner rabbits showed that average total weight gain significantly (P<0.05) improved as rabbits fed the 200PPM enzyme supplemented diets had the best value of 511.67g/rabbit. However, rabbits fed the 100PPM performed (410.83g/rabbit) the same as those fed the 200PPM. Similarly, rabbits fed the 200PPM enzyme supplemented diets gained more (P<0.05) daily weight of 10.40 g/rabbit/day followed by those fed the 100PPM (8.32 g/rabbit/day). The result of the effect of high SCPM showed that feed intake significantly (P<0.05) increased from 47.37 g/rabbit/day to 59.82 g/rabbit/day as the level of SCPM increased in the diets; rabbits fed the high SCPM had higher total weight gain of 484.44 g/rabbit as compared to those of low SCPM (362.78 g/rabbit). The interactive effects of SCPM and enzyme on growth performance of weaner rabbits showed that final live weight, feed intake and total weight gain were significantly (P<0.05) improved as the levels of SCPM and enzyme increased in the diets. In view of the findings, rabbit farmers can supplement 32% of SCPM in the diets of weaner rabbit with 200PPM of quantum blue® without negatively affecting the growth rate and suppressing the digestibility of nutrients by weaner rabbits.

Full textAbstract:
Meat from rabbits offers high nutritive properties as it has high levels of essential amino acids, minerals and vitamins. Rabbit meat is also regarded lean, since it contains less fat than many other meat types. The composition of rabbit meat lipids is also favourable due to higher contents of unsaturated fatty acids compared to other types of meat. The aim of the present study was to examine and compare meat quality from male and female rabbits. A total of 24 rabbits (12 males and 12 females) were used. The rabbits were slaughtered at an age of 17–18 weeks. The following parameters were studied: slaughter traits, colour, pH, cooking loss, tenderness, total fat content and water holding capacity (WHC). Interestingly, the ultimate pH was significantly lower in male compared to female rabbits (p = 0.008). Moreover, cooking losses were higher in the meat from male rabbits (p = 0.001). No other relevant differences were found between meat from male and female rabbits suggesting that sex might be regarded as a minor factor in the production of rabbit meat at the chosen slaughter age.

Rabbit farming is a powerful source of dietary meat, rabbit fluff, and rabbit skins. The research was conducted at the rabbit farm of the Precarpathian State Agricultural Research Station of the Institute of Agriculture of the Carpathian Region of the National Academy of Agrarian Sciences. The article describes the creation of new highly productive genetic populations of rabbits identified as the best options for crossing maternal and paternal forms. Three breeds of rabbits and their hybrids were used for industrial crossbreeding, which are maximally suitable for industrial conditions of intensive production of rabbit meat: rabbit breed Poltava silver, Soviet chinchilla, and New Zealand white rabbit. After the result of the conducted research was found that the combination of crossbred females of the rabbit breed Poltava silver, Soviet chinchilla, and New Zealand white rabbit with purebred males of the Soviet chinchilla and New Zealand white rabbit has a positive effect on the reproductive qualities of female rabbits. Due to combinatorial heredity and compliance with the conditions of keeping in the farm of the Cherkasy Research Station, the best genetic combinations of rabbits, such as 1/2 rabbit breed Poltava silver 1/2 New Zealand white rabbit x New Zealand white rabbit, and 1/2 rabbit breed Poltava silver, 1/2 Soviet chinchilla x New Zealand white rabbit prevails the control group (rabbit breed Poltava silver x rabbit breed Poltava silver) by multiple fertility on 9.2 %, by high fertility on 5.1 %, milk production probably on 8.5 % and the number of weaned rabbits on 14.0 % (P < 0.05), the weight of the nest that was weaned at 28 days of age on 41.2 % (P < 0.01; P < 0.001). The local young rabbits of the third and fourth research groups (1/4 rabbit breed Poltava silver 1/4 New Zealand white rabbit, 2/4 Soviet chinchilla, and 1/4 rabbit breed Poltava silver 3/4 New Zealand white rabbit) at 28 days of age probably prevailed (P < 0.001; P < 0.01)) analogs of the first control group by the indicator of live weights accordingly of 107 and 83 grams, The highest intensity of development up to 28 days of age (P < 0.001) had the young hybrid rabbits of origin 1/4 rabbit breed Poltava silver 1/4 Soviet chinchilla 2/4 New Zealand white rabbit (609 ± 28.26 g), which has more control on 116 gram. By the indicator of live weight at 90 days of age, the local young rabbits of the second research group (1/4 rabbit breed Poltava silver 3/4 Soviet chinchilla) probably (P < 0.05) prevailed over the young rabbits of the first control group (rabbit breed Poltava silver) on 117 and the third research group (1/4 rabbit breed Poltava silver 1/4 New Zealand white rabbit 2/4 Soviet chinchilla) – on 156, and the fourth (1/4 rabbit breed Poltava silver 3/4 New Zealand white rabbit) – on 80 and the fifth (1/4 rabbit breed Poltava silver 1/4 Soviet chinchilla 2/4 New Zealand white rabbit) – on 207 grams. Better tendency to high lifetime fattening, meat, and constitutional indicators had young hybrid rabbits of origin: 1/4 rabbit breed Poltava silver 3/4 New Zealand white rabbit, 1/4 rabbit breed Poltava silver 1/4 Soviet chinchilla 2/4 New Zealand white rabbit.

Full textAbstract:
Regardless of their sex and age, the persistence of 76 rabbits (Oryctolagus cuniculus) translocated onto 5 different sites with relatively low rabbit densities was identical to that of resident rabbits. Emigration and exploratory movements by rabbits from 12 discrete populations were positively correlated with rabbit density and mainly undertaken by adult rabbits. Adult males moved significantly more often and further than adult females. Two peaks in immigration were observed; a large peak (usually in January) immediately following the breeding season, and a second but smaller peak in March which preceded the start of the next breeding season. Again, significantly more adult males than females immigrated. The proportion of rabbits seen in spotlight counts was positively correlated with rabbit density, which suggests that biases in population estimates could result in some situations. No clear patterns on the effects of a variety of weather variables on spotlight counts could be established, but increasing rainfall, wind speed and moonlight may have reduced rabbit activity.

Full textAbstract:
The impact of predation and rabbit haemorrhagic disease (RHD) on population dynamics of rabbits, and the survival of juvenile rabbits, was investigated between July 1999 and March 2000 in North Canterbury, New Zealand. Rabbit abundance and pre- and post-emergent rabbit mortality were monitored on four sites, two of which were subject to predator control. RHD spread naturally through all sites from late November to early December. Rabbit densities declined on all sites, but after the RHD epidemic, declines were significantly greater where populations of predators had not been controlled. Survival of rabbit nestlings was lower where predators were not controlled. All post-emergent radio-collared rabbits died at sites where predators were not controlled, whereas 18% of those collared at sites where predators were controlled survived to maturity. In contrast to the results from previous studies, rabbits born at the start of the breeding season had very high rates of post-emergent mortality, as they appeared to be susceptible to the RHD virus later in the breeding season. The age at which juvenile rabbits become susceptible to RHD, the timing of RHD epidemics, and the abundance of predators are likely to be important in determining survival of juvenile rabbits. This study demonstrates that predation can reduce rabbit populations to low levels, but only in combination with other factors, in this case RHD.

Full textAbstract:
The use of rabbit hemorrhagic disease virus (RHDV) as a biocontrol agent to control feral rabbit populations in Australia, in combination with circulating endemic strains, provides a unique environment to observe the interactions between different lagoviruses competing for the same host. Following the arrival of RHDV2 (GI.2) in Australia, it became necessary to investigate the potential for immunological cross-protection between different variants, and the implications of this for biocontrol programs and vaccine development. Laboratory rabbits of various immune status—(1) rabbits with no detectable immunity against RHDV; (2) rabbits with experimentally acquired immunity after laboratory challenge; (3) rabbits immunised with a GI.2-specific or a multivalent RHDV inactivated virus prototype vaccine; or (4) rabbits with naturally acquired immunity—were challenged with one of three different RHDV variants (GI.1c, GI.1a or GI.2). The degree of cross-protection observed in immune rabbits was associated with the variant used for challenge, infectious dose of the virus and age, or time since acquisition of the immunity, at challenge. The immune status of feral rabbit populations should be determined prior to intentional RHDV release because of the high survival proportions in rabbits with pre-existing immunity. In addition, to protect domestic rabbits in Australia, a multivalent RHDV vaccine should be considered because of the limited cross-protection observed in rabbits given monovalent vaccines.

Full textAbstract:
Context For over 100 years, control efforts have been unable to stop rabbits causing damage to cattle production and native plants and animals on large properties in arid parts of Australia. Warren destruction by ripping has shown promise, but doubts about long-term success and the perceived expense of treating vast areas have led to this technique not being commonly used. Aims This study measured the long-term reduction in rabbit activity and calculated the potential cost saving associated with treating just the areas where rabbits are believed to survive drought. We also considered whether ripping should be used in a full-scale rabbit control program on a property where rabbits have been exceptionally resilient to the influence of biological and other control measures. Methods Rabbits were counted along spotlight transects before warrens were ripped and during the two years after ripping, in treated and untreated plots. Rabbit activity was recorded to determine the immediate and long-term impact of ripping, up to seven years after treatment. The costs of ripping warrens within different distances from drought refuge areas were calculated. Key results Destroying rabbit warrens by ripping caused an immediate reduction in rabbit activity and there were still 98% fewer rabbits counted by spotlight in ripped plots five months after ripping. Seven years after ripping no active warrens were found in ripped plots, whereas 57% of warrens in unripped plots showed signs of rabbit activity. The cost of ripping only the areas where rabbits were likely to seek refuge from drought was calculated to be less than 4% of the cost of ripping all warrens on the property. Conclusions Destroying rabbit warrens by ripping is a very effective way of reducing rabbit numbers on large properties in arid Australia. Ripping should commence in areas used by rabbits to survive drought. It is possible that no further ripping will be required. Implications Strategic destruction of warrens in drought refuge areas could provide an alternative to biological control for managing rabbits on large properties in the Australian arid zone.

Full textAbstract:
SUMMARYEuropean rabbits (Oryctolagus cuniculus), a multifunctional keystone species in the Iberian Peninsula, have drastically declined over past decades. Rabbit decline has been frequently attributed to the arrival of two viral diseases. However, decline was apparently ongoing before the arrival of the diseases, as a consequence of habitat loss and fragmentation. In this paper, the effect on rabbit populations of land-use changes during recent decades in Andalusia (southern Spain) is analysed. Areas favourable for rabbits both at present and during the 1960s are identified, and the environmental and land-use factors that determine these areas established. In areas where the favourability for rabbits has changed during recent decades, main land use changes are assessed to identify possible factors explaining rabbit favourability in these areas. Areas favourable to rabbits are currently determined by factors similar to those during the 1960s; these areas have undergone geographic changes in recent decades, apparently as a consequence of land-use changes in Andalusia. The percentages of the variables that were positively associated with rabbit favourability in both models (current and 1960s) have declined in Andalusia as a whole, and in areas where rabbit favourability has decreased; hence environments suitable for rabbits have become impoverished. Conversely, in both models, environments suitable for rabbits increased in municipalities, where rabbit favourability also increased. The preservation of rabbit-friendly habitats should be a priority for the conservation of this key species in the western Mediterranean.

Full textAbstract:
The study was conducted to assess growth performance and blood profile of rabbit bucks fed dietary inclusion levels of Moringa oleifera leaf meal (MoLM). Thirty (30) rabbit bucks (739.83 to 805.17 g) were balanced for weight and allocated to five groups of 6 rabbits and replicated six times with a buck per replicate in a complete randomized design. Five diets were formulated with incorporation of MoLM at 0.0, 7.5, 15.0, 22.5 and 30.0% and denoted as T1, T2, T3, T4 and T5, respectively. Results on growth performance parameters were not influenced by dietary treatment. Rabbits fed control diet, diets containing 7.5, 15.0 and 22.5% had highest and similar dress weight while those on diet containing 30.0% recorded the least dress weight. Heart weight was highest and similar for rabbit fed control diet, diets containing 7.5, 22.5 and 30.0% while those on diet containing 15.0% had the least heart weight. Rabbits on control diet had highest kidney fats while rabbits on diet containing 7.5 and 30.0% recorded the least and similar kidney fats weight. Bile, left kidney and liver weight were lower for rabbits fed 30.0%. Rabbits fed control diet, diets containing 7.5, 15.0 and 30.0% had highest and similar MCHC while rabbits on diet containing 22.5% recorded the least MCHC. Rabbits on control diet and diet containing 30.0% had the highest) and least lymphocytes, respectively. Rabbits fed control diet, diets containing 7.5 and 15.0% recorded highest and similar neutrophils while rabbits fed diet containing 30.00% had least neutrophils. Rabbits on control diet, diets containing 7.5 and 15.0% had highest and similar albumin while rabbits fed diets containing 22.5 and 30.0% recorded the least and similar albumin. Rabbits on control diet, diets containing 22.5 and 30.0% recorded highest and similar ALP while rabbits on diets containing 7.5 and 15.0% had the least and similar ALP. It is concluded that inclusion MOLM up to 30% had no adverse effect on their growth performance, blood profile reduced kidney fat and liver weight kidney weight. It is therefore recommended that Moringa oleifera leaf meal can be included in the diets of rabbit bucks intended for breeding purposes up to 30.0%.

Full textAbstract:
The development of rabbit fleas from eggs to adults is strongly influenced by both temperature and relative humidity. Normal development only occurs if the temperature is between 15 and 30�C and humidity lies between 70 and 95% RH. This is consistent with the ecology of flea larvae which develop in the rabbit's nest where young rabbits generally maintain a warm, humid environment. At 27�C new adult fleas emerge from pupae about 21 days after egg laying. If environmental air becomes too dry, the water content of the air, even in the rabbit nest, may not always be sufficient to maintain a sufficiently moist microclimate in the nest for the flea larvae. Adult fleas do not appear to have high tolerance to heat or desiccation and, in the more arid parts of Australia, if they left the rabbits during the summer the microclimate of burrows is likely to be too harsh for them to persist.

Paratuberculosis (Johne’s disease) is a chronic invariably fatal enteritis of cattle caused by the bacterium Mycobacterium avium subspecies paratuberculosis and has recently been isolated from wild rabbits. One potential route of transmission of M.a.paratuberculosis from rabbits to cattle is the ingestion of rabbit excreta contaminating pasture. Here we (1) determine the prevalence and level of infection in rabbits and their excreta (2) quantify the level of rabbit faeces contaminating cattle pastures and (3) determine the impact of rabbit faeces on cattle grazing behaviour.

Thymomas are slow growing neoplasms in the cranial mediastinum that can pose life-threatening complications to rabbit patients. Although the incidence of this condition is thought to be low, clinicians and nurses should be aware of the symptoms and morbidity associated with this condition in order to provide rabbits with the correct treatment options.

Full textAbstract:
Context Pindone is used to control rabbits in Australia and New Zealand, but the secondary non-target risks presented by pindone-poisoned rabbits are poorly known. Aims We aimed to generate new data on residual concentrations of pindone in poisoned rabbits for use in a review of the secondary poisoning risks posed to non-target animals in New Zealand. Methods Laboratory rabbits were offered pellet bait containing 0.25 g kg–1 pindone in three trials to simulate a range of bait uptake scenarios: single exposure and low or high chronic exposure. Residual pindone concentrations measured in body tissues of laboratory rabbits that had ingested known exposures of pindone were compared with those in wild rabbit carcasses collected after three pindone-baiting operations. Residues in the faeces of some laboratory rabbits were also measured. Key results Highest concentrations of pindone residues were in the liver and fat tissue of poisoned rabbits, with consistently lower concentrations in muscle tissue. A dose–response relationship between pindone exposure and liver residue concentrations was found only at the highest chronic exposures. Rabbit carcasses collected after field-baiting operations had generally higher pindone residue concentrations than did laboratory rabbits that had ingested known lethal amounts of bait. Unmetabolised pindone was excreted in rabbit faeces. Conclusions The occurrence of the highest residual pindone concentrations in rabbit liver was consistent with the known tissue distribution of anticoagulants in mammals; however, the co-occurrence of similar-range pindone concentrations in rabbit fat has not been previously described. Re-ingestion of soft faecal pellets (caecotrophy) in rabbits that have eaten pindone bait may function as a secondary exposure to increase or prolong their oral exposure to pindone. Some rabbits poisoned following field pindone-baiting operations are likely to have consumed well in excess of a lethal amount of bait. Implications Concentrations of residual pindone in fat and liver of poisoned rabbits suggest that secondary poisoning hazard to some non-target predators and scavengers is high. The lack of field-based assessments of the non-target impacts of pindone is a marked information gap that needs to be addressed.

Full textAbstract:
Mucoid enteropathy/epizootic rabbit enteropathy is a disease of domestic European rabbits (Oryctolagus cuniculus) that has been recognized for nearly 50 years but is still not well understood. Morbidity and mortality are high and can lead to large losses in domestic rabbit production facilities. Recently, the Colorado Wild Rabbit Foundation identified four cases with similar presentations in two species of cottontail rabbits (Sylvilagus spp.) undergoing rehabilitation (2020–2022). Clinical signs, gross pathology, and histopathology findings were consistent with what has been described in domestic rabbits.
