Abstract:

We investigated 3 985 individually housed hens of five original laying lines of two breeds RIR and BPR. The proportion of abnormal eggs out of the eggs laid before the age of 240 days ranged between 7.0% and 9.7%, in dependence on the line. The average number of cracked eggs ranged between 2.5% and 4.4%, double-yolk eggs between 2.2% and 3.0% and shell-less eggs between 2.0% and 2.7%. The correlation between the number of eggs laid at the beginning of the laying period and during the period of observation, and the frequency of double-yolk eggs was positive (r<sub>P </sub>= 0.00 to r<sub>P </sub>= 0.21) and mostly statistically highly significant (P < 0.01). On the other hand, statistically highly significant negative correlations (P < 0.01) were found between the number of eggs laid during the period of observation and the frequency of cracked eggs, where the correlations in the individual lines ranged between r<sub>P </sub>= –0.04 and r<sub>P </sub>= –0.23. Positive correlations, mostly statistically highly significant (P < 0.01), were found between the number of eggs laid during the period of observation and the frequency of shell-less eggs (r<sub>P </sub>= 0.00 to r<sub>P </sub>= 0.15). With the increasing weight of eggs the frequency of abnormal eggs also increased, in particular of double-yolk eggs (r<sub>P </sub>= 0.08 to r<sub>p</sub>= 0.32), for the most part statistically highly significantly (P < 0.01). The correlations between the individual types of abnormal eggs were positive. Statistically highly significant correlations (P < 0.01) were discovered between the frequency of double-yolk eggs and cracked eggs (r<sub>P </sub>= –0.02 to r<sub>p</sub>= 0.22) on the one hand and, between double-yolk eggs and shell-less eggs (r<sub>P </sub>= 0.16 to r<sub>P </sub>= 0.24) on the other.

Abstract:

Chicken eggs and duck eggs can be a source of transmission of Salmonellosis. Salmonella bacteria can penetrate the eggshell, or the egg's contents can become directly contaminated with Salmonella in the reproductive organs before the shell covers the egg. This research aims to analyze Salmonella sp in chicken and duck eggs at the Antasari Traditional Market in Banjarmasin, Indonesia. Samples were taken by purposive sampling with the criteria for cracked/broken eggs and intact eggs: 3 chicken eggs and three duck eggs from 6 traders so that the total sample was 24. For the identification of bacteria, microscopic tests and biochemical tests were used on the identification media. The results showed Salmonella sp in duck eggs and no Salmonella in chicken eggs. In all samples of chicken and duck eggs, 12.50% of Salmonella sp, 37.50% of Klebsiella sp, 12.50% of Proteus sp, and 37.50% of Pseudomonas sp were found. Suggestions for consumers are to pay more attention to the hygiene and sanitation of traders before buying eggs, choose clean eggs, store eggs in the refrigerator, and cook eggs until they are cooked.

Abstract:

Table eggs are versatile foodstuffs used in various food products. Eggs are often consumed or incorporated into other food products to enhance taste and nutrition and act as an emulsifying agent. Too often the consumption of contaminated eggs leads to foodborne illnesses in people. When whole eggs or egg products come into contact with contaminated surfaces or other contaminated eggs, pathogens can spread from one egg to another. Research has been conducted to uncover ways to protect whole eggs and their products from contamination by coating the egg’s exterior with edible coatings. Mineral oil, among other edible oils, is one such oil shown to be effective in reducing the bacteria in eggs when applied to the egg’s exterior. With the average consumer becoming more aware of the chemicals used in the preservation of food, some researchers have started to explore more natural solutions to minimize the contamination of food products. The use of essential oils to prevent contamination has been studied and analyzed for their antimicrobial properties in the inhibition of the growth of foodborne pathogens. The oils used in this current study are Oregano and Clove Oil. Both oils used individually and combined compared to a positive control showed no differences (p > 0.05). Interestingly, when the oils were combined 1:1 there was a difference of 0.66 log in the survival bacterial counts compared to the positive control. However, this difference was also not significant (p > 0.05).

Abstract:

An on-line system which based on acoustic resonance employed digital signal processer (DSP) as its core device for eggshell crack detection. The system consists of the IR trigger for detecting the egg’s coming, the motor drive for driving the DC motor, the signal conditioning circuit for signal amplification and filter and DSP for control and signal processing. Based on the analysis of response signal of eggshell which excited with a light mechanical, four featured descriptors were exacted for discriminating intact and cracked eggs. By using the on-line system for detection of cracked eggs, the identification rates of intact eggs and cracked eggs were 93.75% and 96.25%, respectively. This system can detect 5 eggs within one second, it completely meet the needs of on-line detection.

Abstract:

In order to achieve higher recognition rate of unfertilized eggs, the paper proposes a new method based on the area feature of egg's vertical image and the classifier BP network. The eggs hatched 2-5 days are selected as the experiment objects in our study. Four kinds of feature, including the gray feature and the area feature extracted from the egg's vertical image and the egg's horizontal image, respectively, are sent to BP network to accomplish the recognition of unfertilized eggs. The experiment results indicate that the area feature of egg's vertical image contains more category information, and this kind of feature classified by BP network can reach 97.86% of recognition rate. Moreover, it is almost free from some external factors, such as light, camera, eggshell and the parameters of BP network. While the other features sent to BP network, the recognition rate can be reached to only 86.43%. This study provides an effective and useful method to recognize unfertilized egg in early incubation stage.

Abstract:

Eggs are a nutritious and important food in human daily diet, which is considered as a protein source of food. The most acceptable index for evaluating egg quality is Haugh unit with two factors, i.e. the weight of intact egg and the height of broken egg’s albumin. Hauge unit has three classification: firm (higher than 72), reasonably firm (higher than 72), and weak (less than 60). Average results for Haugh unit on the first, fourth, eighth, twelfth, and sixteenth days (five eggs in each step) were 113.39, 91.47, 74.56, 72.04, and 64.14 respectively. On the first, fourth and eighth days, eggs were intact but the quality of the eggs decreases on the next days. This research aims to sort healthy eggs from others and swell the rate of sorting.

Abstract:

Thesis (M.Sc. (Agric)) --University of Limpopo, 2010
An experiment was conducted to determine the effect of egg weight on hatchability, hatch-weight and subsequent productivity of Venda chickens. A total of 360 Venda chicken eggs based on their weights were collected within one week and assigned to four treatments with five replicates of 18 eggs per replicate. A randomized design was used. The four treatment weights were below 49 g, between 50 and 59 g, between 60 and 69 g and above 70 g. the eggs were incubated for 21 days. The chicks were raised up to 13 weeks based on their treatments but fed a similar diet. Egg weight was positively and strongly correlated (r2 = 0.727) with hatchability. Similarly, egg weight was positively and strongly correlated (r2 = 0.0.953) with chick hatch-weight. Between one and seven weeks old, Venda chicks hatched from heavier eggs ate less (P< 0.05) than those hatched from lighter eggs. Heavier eggs hatched chicks with better (P< 0.05) feed conversion ratio. However, chicks hatched from heavier eggs tended to have higher (P< 0.05) live weight at seven weeks old than those hatched from lighter eggs. Heavier eggs tended to hatch chicks that had higher (P< 0.05) mortality rates. However, metabolisable energy and nitrogen retention of the chicks aged seven weeks was not (P> 0.05) affected by egg weight. Growth rate and live weight of the chicks aged between one and seven weeks were optimized at different Venda chicken egg weights of 56 (r2 = 0.514) and 60 (r2 = 0.870) g, respectively. Egg weight had no (P> 0.05) effect on metabolisable energy, feed conversion ratio, growth rate, live weight, carcass weight and carcass parts of Venda chickens aged between eight and 13 weeks except fat pad weight. Venda chickens hatched from lighter eggs had lower (P< 0.05) fat pad weights than those hatched from heavier eggs. Meat samples of chickens hatched from lighter eggs had higher (P< 0.05) nitrogen contents. It is concluded that Venda chicken egg weight affects (P< 0.05) egg hatchability, chick hatch-weight, growth rate, live weight and carcass characteristics of the chicken. However, these variables are optimized at different egg weights. This has implications on selecting eggs for incubation.

Abstract:

Thesis (MA.Agricultural Management (Animal Production)) -- University of Limpopo, 2013
The objectives of the study were to evaluate the productivity of the Vhembe egg production project and determine the management and socio-economic factors affecting productivity. The data were collected from 2005 to 2007. Thirty-two farmers from four municipalities were randomly selected. Each household received a once-off unit consisting of a cage with eighteen point of lay chickens 4x50 bags of laying mesh, feeding and drinking troughs. Production records from sampled farmers were used in the analysis. Data included monthly egg production, eggs consumed, eggs sold, income from eggs, production costs, monthly feed utilization and mortality. Primary data on educational standards, socio-economic characteristics (age and gender of the household head, farming size, level of education and alternative income, were collected using a questionnaire. The study revealed that sex, age and educational level had impact on production as low production was associated with older farmers and low level of education. These factors should be considered when planning community projects. Chicken rearing and ownership is often shared among the family members, in this study, the management was predominantly by women (63%) and children (18%). This may be an indication that if assistance efforts are targeted towards women, village poverty could be significantly reduced. It is concluded that the low income accrued from the project explains the reason for high abandonment or neglect of the project. The income received from the project is smaller than the government grants and as such not attractive. It is not surprising that presently most farmers have abandoned the project. It is noted that if labour costs had been taken into consideration, the project would be running at a serious loss and the resultant output would discourage even the most enthusiastic farmers.

Abstract:

Post-translational modifications (PTMs) of proteins play significant roles in regulation of biological activities and signal transduction. Examining their diversity is critical for understanding the mechanisms of cellular regulations. Among the various techniques employed for identification of PTMs, mass spectrometry has become a more and more important tool for detecting and mapping these covalent modifications and quantifying their changes. The two projects described in this dissertation focus mainly on the method development for characterization of two major PTMs, disulfide bonds and glycosylation. In the first project, the disulfide bond pattern of a rhamnose-binding lectin SEL24K from the Chinook salmon Oncorhynchus tshawytscha was assigned unambiguously based on a multi-enzyme digestion strategy in combination with MALDI-TOF mass spectrometry analysis. The disulfide bond pattern was found to be symmetrical in the tandem repeat sequence of SEL24K. More importantly, an interesting phenomenon of gas-phase scrambling of disulfide bonds was observed during MALDI mass spectrometry analysis and a possible mechanism for this surprising scrambling was proposed. To the best of our knowledge, this is the first report of disulfide bond scrambling in the gas phase during MALDI-MS analysis. This observation has important ramifications for unambiguous assignment of disulfide bonds. In the second project, the glycosylation of a glycoprotein ZPA from the vitelline envelope of Xenopus laevis was determined by applying a strategy of general proteolysis coupled with mass spectrometry. The vitelline envelope glycoproteins were first separated through SDS-PAGE. A nonspecific in-gel pronase digestion was performed on the excised band of ZPA to produce informative small glycopeptides. Lectin affinity chromatography was used for the enrichment of these glycopeptides. An in-gel PNGase F digestion was also carried out to release the N-linked glycans from ZPA. The enriched glycopeptides and glycans were finally analyzed by MS and MS/MS techniques on MALDI-TOF and MALDI-TOF/TOF instruments.

Abstract:

Egg adhesiveness is one of the major problems in carp artificial breeding. The appropriate elimination of egg adhesiveness impacts the effectiveness of the breeding. This article discusses two used methods of carp egg adhesiveness removal: tannic acid+water and milk+water+salt solutions. Milk, water and salt solution was based on the following proportions: 1 litre of milk + 7 litres of water +50g of NaCl. Adhesiveness is removed from fertilized eggs in bowls by mixing them with geese feathers for no shorter than 60 minutes. The tannic acid solution was prepared by mixing 7 grams of tannic acid powder with 5 litres of water. 1 litre of solution is immediately poured into a bowl with fertilized eggs. Adhesiveness is removed from fertilized eggs in bowls by intensively mixing them for 10 minutes. After fertilization and removal of adhesiveness, the eggs were transferred into Weiss jars. The results showed that during the process of incubation, 3.7 million eggs were fertilized; out of them 1.6 million were rid of adhesiveness by milk solution, 2.1 – by tannic solution. It is plausible that unfavourable environmental conditions influenced the low egg vitality. 750 000 (47%) carp larvae hatched from milk solution treated eggs, while 800 000 (38%) of larvae hatched from the eggs treated with tannic solution.

Abstract:

The research paper presents the study of correlations between morpho productive characters in hens double productivity of Marans, Orpington, Gât golaș moldovenesc breeds and their intraracial hybrids. The link between body weight and Metatarsus length, the age of laying the first egg, and the number of eggs at 40 weeks were analyzed; as well as the correlation of the weight of the egg with the average body weight, the age of laying the first egg, and the number of eggs at 40 weeks were appreciated. Thus, both positive and negative correlations were established between different characters. The highest positive correlation proved to be between body weight and Metatarsus length, the obtained values being authentic for all 5 lots of chickens taken in the study (correlation coefficient is between 0,49 – 0,69). The values obtained between these two characters allow us the selection to be carried out in the direction of increasing flesh production, on the other, for the production of eggs, increasing the weight of the body will lead to a decrease in the number of eggs, including the decrease of the age of the laying first egg, and in particular, in the hybrid lots as ♀Marans × ♂ Gât golaş moldovenesc (r= -0,32±0.07) and ♀ Orpington × ♂ Gât golaş moldovenesc (r =-0,39±0,06).. The selection work will also be complicated for other characters where negative correlations have been established, for example, increasing the weight of the egg will lead directly to a decrease in the age of laying the first egg and the number of eggs, which indicates practically the uselessness of selecting hens by this character, neither for egg production nor for meat production.

Abstract:

The research purpose was to study the ovocidal properties of commercial Saponin DAB 9/10. Its standard aqueous solutions were studied. The test object was eggs of the nematode Toxocara canis. They were obtained from gonads of fertilized female Toxocara nematodes isolated from carnivores. Laboratory studies were conducted according to the Disinfectant Testing Guidelines in Veterinary Medicine. After contact with freshly isolated helminth eggs, the egg suspension was incubated in a thermostat at 28±2 оC. One-hour aeration was performed daily in petri dishes with nematode eggs. Stage 1 larvae were monitored for 2 weeks. At day 21, mechanical exposure was produced on shells of helminth eggs and a biological sample was evaluated on laboratory mice. No effective ovocidal action was observed on Toxocara eggs under the effect of different concentrations of Saponin DAB 9/10. The experimental helminth eggs developed unchanged at such time as the control eggs. A biological test on the laboratory mice was positive. Saponin DAB 9/10 did not provide any desired effect for disinvasion against the causal agent of toxocariasis T. canis.

Abstract:

Ducks have lower hatchability rate than other poultry species, ranging about 65- 82%, and duck egg hatching is more difficult than chicken egg hatching. The present study aimed to evaluate the effect of spraying incubating duck’s eggs with the olive oil, ethanol alcohol and distilled water on embryonic mortality and hatchability rates. Eight hundred fertilized eggs were used with an average weight of (65-73) g divided into four groups, each group subdivided into four sub-groups were sprayed with distilled water at 37°C temperature, olive oil and ethanol alcohol 70%, and the control group without spraying. The first group G1 was sprayed on 1st day of incubation, the second group G2 was sprayed at 7th day of incubation, and the third group G3 was sprayed at 14th day of the incubation period, and the fourth group was sprayed at 21st day of the incubation. The results revealed that the hatching rate was significant raising (p ≤ 0.05) in eggs sprayed by water in each periods of incubation when compared with other spraying groups. Also, the embryonic mortality rate registered a significant decreasing (p ≤ 0.05) in eggs spraying by distilled water during incubation periods compared with other spray group. In conclusions, from present results are established that the spraying Iraqi duck's eggs by distilled water could improve hatchability rate and decrease the mortality rate of embryo at variant periods of incubation.

Abstract:

In the prevention of parasitic diseases, an important place is occupied by the search for new highly effective chemicals for the disinfection of environmental objects. When selecting disinfectants, helminth eggs are often used as test objects. The availability of high-quality and standard test material contributes greatly to successful research. However, publications devoted to the methodological side of this problem are clearly not enough. Ascaridata eggs (Ascaris suum, Toxocara canis, etc.) are the most resistant to chemicals, so testing on them allows us to identify the most effective means for the purposes of disinfection. Special attention should be paid to such an object as Enterobius vermicularis, the causative agent of enterobiasis, the most common of helminth infections in humans. This paper describes methods for obtaining standard egg cultures of such test objects as A. suum and E. vermicularis. A more standard A. suum egg culture is facilitated by material collected only from females with high egg viability, as well as the destruction of egg conglomerates in a suspension using sodium hypochlorite. Standardization of the E. vermicularis egg culture is only achieved by taking samples containing healthy viable eggs after the preview.

Abstract:

The output of poultry products by poultry enterprises in the world was mainly determined by feeding techniques and poultry productivity. The productivity of poultry is characterised by the rate of egg-laying or the number of eggs produced per hen a year and affected by the availability and diversity of feed materials (especially protein). In recent years, researchers have focused on legumes of various species as promising sources of protein for livestock production, such as beans, peas, lupine, alfalfa etc.; therefore, in Latvia more attention is paid to the production of protein crops or legumes. The aim of the research was to identify the impact of domestically sourced legume seeds included in diets for laying hens on the economic performance of egg production. Two kinds of protein crops were examined by the research: peas `Bruno` and dried alfalfa pellets. Feeding laying hens with peas or dried alfalfa pellets made it possible to produce eggs with a heavier weight (55.28-67.07%), which in turn makes it possible to increase revenues (10.3-12.9%) from the sales of eggs with the same feed consumption.

Abstract:

The research purpose was to study seasonal characteristics of nematodirosis manifesting in the Edilbaev sheep introduced into the Kulunda Steppe of the Altai Region. Fecal samples collected from spontaneously infected animals were studied by coproovoscopic method per Fülleborn. The Nematodirus infection in sheep in different seasons of the year was characterized in view of incidence rates (prevalence, %) and infection intensity (average number of eggs per gram of feces (egg/g) per one studied and infected animal). A total of 240 fecal samples were examined. It was found that annual dynamics of the epizootic process was typical for Nematodirus. The minimum Nematodirus infection rate in sheep was recorded in July (prevalence = 10.0%) with an increase to 68.8% observed in August and maximum values of 95.6% recorded in October. Similar results were detected for the intensity of infectious process of nematodirosis, namely, the maximum number of eggs in fecal samples per examined and infected animal was recorded in autumn, 193.1 and 235.9 egg/g, accordingly, and the minimum in April, 2.0 and 20.6 egg/g, accordingly. The summer-autumn seasonal pattern of the infectious process of nematodirosis in sheep was due to the maximum contamination of land with helminth eggs during this period.

Abstract:

The article describes a method for isolating Toxocara canis larvae from chorions. Nematode larvae can serve as a specific antigen in the diagnosis with serological reactions. The study material was cultures of Toxocara eggs obtained from female nematode gonads. Toxocara eggs were stored in a 4.0% formalin solution or a 1.0% hydrochloric acid solution. Sexually mature female Toxocara species were obtained by isolating helminths from the intestines of carcasses of naturally infected carnivores. For artificial isolation of Toxocara larvae from eggs, a method of their short-term incubation in the bile of ruminants was used. The nematode egg culture was put on a heated magnetic stirrer. A magnet in plastic of 1.5–3.5 cm was placed in a sample, and heating to 38±1 оC was turned on. After 30-minute exposure, the larvae were washed in the saline. For convenience, they may be placed in a Berman device at 38±1 оС. The materials freshly obtained and stored for 3 months showed a high percentage of larval yield from eggs. The stored material showed a rather worse result for the 1st year.

Abstract:

Infrared laser as a heat source could induce gene expression by activating heat promoter genes in Caenorhabditis elegans, as previously reported. In this study, we innovatively used a 266-nm laser to irradiate C. elegans for only one second and observed a significant inhibition of the overall number of eggs laid (P < 0.0001) and the first day egg laying (P=0.005). This is the first study to establish how light with a wavelength of 266-nm can influence a life activity such as laying eggs in C. elegans.

Full text

Abstract:

A previous risk assessment (Opens in a new window) from the Advisory Committee on the Microbiological Safety of Food (ACMSF) in 2016 concluded that due to the significant reduction in the risk from Salmonella in UK-produced hen shell eggs produced under a recognised farm assurance scheme (Lion Code or equivalent), the risk to consumers from eggs produced under these schemes was ‘very low’. This risk assessment led the FSA and FSS to update their consumer advice on the consumption of eggs in 2017, stating that vulnerable groups could consume raw or runny eggs produced within an assurance scheme. This risk profile will examine the current situation of Salmonella in UK-produced table eggs, and the factors that may influence the current risk of Salmonella in UK-produced eggs and highlight any that have changed since the risk assessment provided by the ACMSF in 2016.

Abstract:

The objectives of the project were to develop a successful protocol for cryopreservation of penaeid germ plasm in order to preserve a pathogen-free broodstock nucleus for commercial exploitation of marine shrimp in aquaculture. The critical parameters to be characterized in the project were: 1. Determination of chill sensitivity and chill tolerant embryonic stages, including a full description and time course study of embryonic developmental stages. 2. Development of protocols for loading and removal of cryoprotectant agents (CPAs) from embryos; determination of optimal concentrations and duration of loading. 3. Characterization of the toxicity of the selected CP As and 4. Establishing optimal cooling and thawing procedures. Studies were performed on two penaeid species: Litopenaeus vannamei (in the USA) and P. semisulcatus (in Israel). The effect of incubation temperature on embryonic development rate and hatching success was studied in L. vannamei, showing that spawns maybe maintained at temperatures ranging from 24°C to 30°C, without compromising hatchability. Embryonic development extends from 12 hr to 19 hr at 30°C and 24°C, respectively. Studies showed that advanced embryonic developmental stages were chill tolerant in the two studied species, but P. semisulcatus could better endure lower temperatures than L. vannamei. A large number of experiments were performed to determine the optimal CP As, their concentration and duration of loading. Permeating (e.g. glycerol, methanol, DMSO, 1,2- propanediol, ethylene glycol, glucose) and non-permeating CPAs (sucrose, PVP, polyethylene glycol) were tested and several combinations of permeating and non-permeating CP As, on fertilized eggs (embryos), nauplii and protozoeae. In general, nauplii tolerated higher CPA concentrations than eggs and nauplii were also more permeable to radiolabeled methanol. Chlorine treatment intended to remove the chitinous envelop from eggs, did not increase dramatically the permeation of radiolabled methanol into eggs. Cooling eggs, nauplii or protozoeae to cryogenic temperatures, by either vitrification or slow cooling protocols, did not result in full survival of thawed samples, despite exhaustive attempts testing various protocols and CP As. Results seemed more encouraging in freezing of nauplii in comparison to eggs or protozoeae. Successful preliminary results in cryopreservation of spermatozoa of P. vannamei, will facilitate preservation of genetic specific to some extent.
