This study designated to evaluate the competency of veterinary students who are trained in Basra Veterinary Hospital-Basra governorate- Iraq. In the student life, performance evaluations should revealed areas of excellence. Very little research has considered in training evaluation in a veterinary sciences. The test was carried out by the students of the Veterinary Medicine College- Basra University from the third and fourth stages who succeeded to the fourth and fifth stages. One hundred and two students participated in the performance evaluation, 47 students from the fourth stage and 55 from the third stage. Totally, there were 100 multiple questions presented to the participants. The questions included 13 aspects of veterinary sciences disciplines. The results of this study revealed that the evaluation of the competency of veterinary students in the fourth stage was higher compared to the third stage by comparing the percentage of correct answers for both groups (65.86 and 60.95) respectively. In addition, the two groups recorded high percentage in physiology correct answers and low percentage in animal hygiene for the fourth year students and infectious diseases for the third year.

With continuous rapid expansion of the human population there is escalating demand for resources, including human and veterinary pharmaceuticals. This has lead to rapid development of global pharmaceutical industry and with that increase in issues caused by pharmaceutical products. In recent years a great concern has been expressed over the occurrence and persistence of pharmaceutical products in the environment and their potential impact on environment. Owing to this the new branch of science called environmental pharmacology has sprouted. Environmental pharmacology deals with dispersion and impact of pharmaceutical products on environment. Solutions need to be suggested to save this only liveable planet from ill effects of these pharmaceutical products. This has given birth to the science of Ecopharmacovigilance (EPV).

Hospitals (medical & veterinary) and slaughterhouse effluents were the most contaminating effluents and need to be paid more attention due to pathogenic bacteria related to animal and public health concern. Two bacterial isolates such as E. coli and Salmonella from six medical hospitals, five veterinary hospitals and five slaughter houses were isolated to find out the antibiotic resistance pattern by using disc diffusion method. The antibiotic resistance patterns of identified isolates showed that Ampicillin, Ciprofloxacin, Enrofloxacin, Pefloxacin, Colistin, Erythromycin, Oxytetracycline were 100%, Doxycycline was 83%, Gentamycin was 50% and Neomycin was 33% resistance to medical isolates and Ampicillin, Enrofloxacin, Pefloxacin and Erythromycin were 100%, Ciprofloxacin was 40%, Colistin was 60%, Doxycycline was 80%, Gentamycin was 20%; Neomycin and Oxytetracycline 80% resistance to veterinary hospital isolates and Ampicillin, Enrofloxacin, Ciprofloxacin, Pefloxacin, Colistin, Oxytetracycline, Gentamycin, Doxycycline and Erythromycin were 100% and Neomycin was 40% resistance to slaughter houses isolates of E. coli. The level of resistance of Salmonella positive isolates was found Ampicillin, Enrofloxacin, Pefloxacin, Gentamycin and Erythromycin to 100%, Ciprofloxacin was 67%, Oxytetracycline was 33% but Colistin and Neomycin was found sensitive to the isolates from both medical and veterinary hospital. Results indicated that hospitals and slaughter houses waste effluent has multiple-antibiotic resistance against E. coli and Salmonella.International Journal of Natural Sciences (2015), 5(2) 52-58

Pharmacovigilance deals with the study of adverse drug reactions. It provides information from which to detect adverse update of drugs. The environmental impact of drugs is a rapidly evolving problem. Withdrawal of diclofenac from veterinary practice and various other such exampleshaving direct impact on the environment led to the development ofa newdiscipline which may be called as “pharmacoenvironmentology”. Evaluation of the potential environment risks posed by the medical product is thus needed. This impact should be assessed, and on a case by case basis, special arrangements to limit it should be envisaged.International Journal of Human and Health Sciences Vol. 04 No. 01 January’20 Page : 19-25

The One Environmental Health research approach, a subspecialty of the One Health initiative, focuses on toxic chemicals. Distinct disciplines work together to give a holistic perspective of a health concern through discrete disciplines, including, but not limited to, public health and the medical and veterinary sciences. In this article, we illustrate the concept of One Environmental Health with two case studies. One case study focuses on alligators and contributions to the field of endocrine disruption. The other case study focuses on whales and contributions to understanding carcinogenic metals. Both studies illustrate how the health of sentinel organisms has the potential to inform about the health of humans and the ecosystem.

In 2005, the new legislation for pharmaceuticals came into effect. Since then environmental risk assessments are required for all new marketing authorisation applications. The German Federal Environment Agency has been assessing the environmental impact of 136 veterinary and 134 human pharmaceuticals. The authorisation of pharmaceuticals has shown that the authorisation of some groups of substances have to be combined with risk mitigation measures. Environmental risks may also arise from those pharmaceuticals which were authorised before the environmental risk assessment was added to the requirements of authorisation. Four examples of “existing” pharmaceuticals, i.e. diclofenac, ethinyl estradiol, ivermectin, and florfenicol are highlighted in this article. Risk management options for veterinary and human pharmaceuticals are discussed.

High throughput sequencing (HTS) creates an opportunity for comprehensive genomic studies. It can be applied in veterinary science, bacteriology and virology, diagnostics of animal diseases, food safety, examinations of the composition of environmental samples, and even in veterinary vaccinology. Thus HTS a wide-ranging method that can be applied in different areas of the One Health approach. In particular, the whole genome sequencing (WGS) of bacteria is routinely used in food hygiene and outbreak investigations for phylogenetic analysis of pathogenic bacteria isolated from various sources across timeline, molecular characterisation of bacteria, plasmids, antibiotic resistance and identification of virulence factors. Metagenomics can be used to characterize the composition of microbiota in environmental samples. It makes it possible to obtain a taxonomic identification of bacteria, fungi or plants present in a metasample. It can also be used for the monitoring and epidemiological tracing of viruses, such as SARS-CoV-2. The transcriptomic approach makes it possible to study the expression of genes associated with various infections and diseases. HTS is a highly versatile method, but the selection of the proper application is crucial to obtain expected outcomes. The paper presents some HTS approaches and examples of research in veterinary science.

The increasing need for animal protein has exerted pressures on the current animal production system. One of the alternatives found by producers to improve animal performance has been the use of veterinary drugs, especially antibiotics. However, its indiscriminate use can be a risk to the environmental balance of the producing locations since Brazil has approximately 42 million pigs. With this herd, pig farming represents a great potential for generating environmental impacts. As an alternative use of the large volume of liquid pig manure generated, many producers have been using this slurry in the soil as a bio fertilizer. Residues of veterinary drugs are capable of accumulation with environmental matrices and leach into water resources. In this sense, it is mandatory to dedicate more efforts on the study of techniques and processes for the treatment of organic effluents contaminated by veterinary drugs. Low-cost and environmentally friendly alternative treatment systems are necessary, in order to minimize the entry of these contaminants into the environment. Therefore, the composting process, defined as aerobic microbial decomposition process of organic matter, can be an alternative for treating the effluents contaminated by veterinary drugs. This review to aims to create awareness in the academic community regarding the veterinary drug residues and their contamination potential in different environmental matrices, as well as evaluating the composting process as a technique to minimize the impacts of the swine activity waste on the environment.

Many parts of the world, and especially developing countries, are experiencing severe water shortage problems. This is causing increased use of untreated or partially-treated wastewater for irrigation. Consequently, many pollutants such as surfactants, present in wastewaters, could influence fate and transport of agricultural chemicals in soils. Therefore, a field lysimeter study was undertaken to investigate the effect of non-ionic surfactant, Brij 35, on the fate and transport of two commonly used antibiotics, oxytetracycline (OTC) and monensin (MON), and an herbicide, metribuzin. Twenty seven PVC lysimeters, 1.0 m long x 0.45 m diameter, were packed with a sandy soil to a bulk density of 1.35 Mg m-3. Cattle manure, containing these compounds, was applied at the surface of the lysimeters at the recommended rate of 10 t/ha. Three types of wastewaters, i.e., good, poor, and very poor, were simulated by using three aqueous Brij 35 concentrations of 0, 0.5 and 5.0 g L 1, respectively, and applied to lysimeters, in triplicate, for each compound. Over a 90-day period, soil and leachate samples were collected and analyzed. Sorption experiments were also conducted for all compounds in the laboratory in the presence and absence of surfactant. Overall, the OTC and monensin mobility in the lysimeter study significantly increased in the presence of the surfactant (p<0.01). The maximum OTC concentration in the leachate was 102.72 µg L-1 for the surfactant concentration of 0.5 g L-1, which was higher than both control and the high surfactant concentration treatment. Unlike OTC, monensin leaching increased significantly with increasing surfactant concentration (p<0.01), and the maximum detected concentration in the leachate was 5.83 µg L-1 for the surfactant concentration of 5.0 g L-1. The laboratory study also showed that the sorption coefficient of OTC significantly reduced in the presence of the surfactant (p<0.05); it changed from 23.55 mL g-1 in the aqueous medium to 19.49, 12.49 and 14.53 mL g-1, respectively, in the presence of the surfactant at concentrations of 0.25, 2.5 and 5 g L-1. It may, however, be noted that the sorption coefficient was higher for the highest surfactant concentration used. However, in the case of monensin, the sorption coefficient reduced significantly (p<0.01) from 120.22 mL g-1 in the aqueous medium to 112.20, 100 and 63.09 mL g-1 with surfactant concentrations of 0.25, 2.5 and 5 g L-1, respectively. Herbicide movement may also be affected by surfactants; therefore, the mobility of a commonly-used herbicide, metribuzin, was investigated. In the presence of the surfactant, a significant increase in metribuzin movement (p<0.05) in the soil profile was observed. The highest metribuzin concentration in the leachate was 84.80 µg L-1 for the 5.0 g L-1 surfactant treatment. However, no significant differences on mobility were observed for the two treatments with differing surfactant concentrations. The laboratory sorption study showed that the sorption coefficient of metribuzin significantly decreased with increasing surfactant concentration (p<0.05). It can be concluded that nonionic surfactants may increase the mobility of agricultural pollutants, including antibiotics and herbicides, in soil. Therefore, irrigation with poor quality water can potentially cause ground water contamination.
Plusieurs régions du monde, particulièrement celles en voie de développement, souffrent d'une pénurie d'eau. Afin de composer avec l'augmentation de la demande en produits alimentaires et la pauvreté au sein d'une population croissante, des eaux usées partiellement- ou non-traitées servent souvent a l'irrigation. Il en survient que plusieurs polluants, incluant des agents de surface, peuvent être présents dans ces eaux d'irrigation et influencer le devenir et le transport de pesticides et antibiotiques dans les sols agricoles. Une étude lysimétrique au champ visa à évaluer l'effet de l'agent de surface non-ionique, Brij 35, sur le devenir et le transport de deux antibiotiques, l'oxytétracycline (OTC) et le monensin (MON), ainsi qu'un herbicide le metribuzin. Vingt-sept lysimètres en PVC, hauteur 1.0 m  diamètre intérieur 0.45 m, furent remplis d'un sol sablonneux à une densité apparente de 1.35 Mg m-3. Du fumier de vache, contenant les composés sous étude fut épandu à la surface des lysimètres au taux recommandé de 10 Mg ha-1. Pour chaque polluant, chacun des trois lysimètres répliquats fut arrosé d'une des trios solutions aqueuses de l'agent de surface Brij 35 (0, 0.5 ou 5 g L 1), représentant une qualité d'eau d'irrigation 'bonne,' 'mauvaise' ou 'très mauvaise'. Sur une durée de 90 jours, des échantillons de sol et de lixiviat furent obtenus et analysés. Des expériences en laboratoire additionnelles furent conduites en réacteur pour évaluer le potentiel de sorption des composés à l'étude. La présence de l'agent de surface non-ionique Brij 35 diminua de façon significative (p<0.05) le coefficient de sorption de l'OTC, soit de 23.55 ml g-1 en milieu aqueux, à 19.49, 12.49 et 14.53, respectivement, en la présence de 0.25, 2.5 et 5 g L-1 de Brij 35. La mobilité de l'OTC fut significativement moindre en présence de 0.5 g L-1 vs. 5.0 g L 1 de Brij 35. La concentration maximale en OTC du lixiviat fut de 102.72 µg L-1. Le coefficient de sorption du MON diminua de façon significative (p<0.05) de 120.22 mL g-1 en milieu aqueux, à 112.20, 100 et 63.09 mL g-1, respectivement, en présences de 0.25, 2.5 et 5 g L-1 de Brij 35. Si la demi-vie (t½) du MON fut de 5.72 jours en eau du robinet, elle augmenta à 9.62 et 11 jours, respectivement, en presence de 0.5 et 5.0 g L-1 Brij 35. La concentration maximale de MON détecté dans le lixiviat fut de 5.83 µg L-1. Dans le laboratoire, la sorption/désorption de l'OTC fut comparé à celle du sulfachloropyidazine (SCP) en présence et en absence d'un agent de surface non-ionique. En contraste à l'OTC, la présence d'un agent de surface augmenta de façon significative le potential de sorption du SCP au sol, tel qu'en témoigne le coefficient de sorption coefficient (KF) pour le SCP qui augmenta de 19.95 mL g-1 en absence de Brij 35, à 95.49 mL g-1 et 66.06 mL g-1 en présence de Brij 35 à des concentrations de 2.5 g L-1 et 5 g L-1, respectivement. Le coefficient de désorption de l'OTC en l'absence d'agent de surface fut de 61.58 mL g-1, tandis qu'en présence de 2.5 g L-1 Brij 35 elle diminua à 50.35 mL g-1. Comparativement, pour le SCP, les valeurs correspondantes furent de 1.24 and 1.38 mL g-1. Un phénomène d'hystérèse dans le cas du SCP en présence vs. absence de Brij 35 indiqua le bas potentiel de lixiviation du SCP en présence d'un agent de surface. Cependant, l'OTC se montra facilement désorbée en présence de Brij 35 en forme micellaire. Vu les inquiétudes quant a l'utilisation constante d'herbicides dans la production agricole actuelle, le potentiel d'une mobilité accrue de l'herbicide métribuzine en présence d'agents de surface s'avéra digne d'attention. La métribuzine présenta une mobilité accrue et une moindre affinité de sorption au sol et t½ en présence de micelles de Brij35 comparé à en leur absence. Les agents de surface ont augmenté la mobilité en sol des polluants étudiés. L'irrigation avec des eaux de mauvaise qualité peut donc poser un risque de contamination des eaux souterraines.

Ovariohysterectomy and castration are common surgical procedures in small animal practice that can result in clinically significant postoperative pain. One way of controlling postoperative pain is administration of a single analgesic or a combination of different classes of analgesics prior to the onset of noxious stimuli. A constraint to the perioperative use of traditional opioids and non-steroidal anti-inflammatory drugs (NSAIDs) is their undesirable side effects. In this series of experiments, the preventive (pre-emptive) analgesic efficacy of two popular human analgesics, tramadol (an ?atypical? opioid) and parecoxib (a NSAID with selective COX-2 inhibition) was evaluated in dogs. Initially, the efficacy and renal safety of parecoxib, tramadol and a combination of parecoxib, tramadol and pindolol (a -adrenoceptor blocker and 5-HT1A/1B antagonist) were screened in anaesthetised healthy dogs. These analgesics increased the dogs? nociceptive threshold to mechanical stimuli, without causing significant alterations in the dogs? glomerular filtration rate (GFR) estimated by plasma iohexol clearance. Subsequently, the efficacy of tramadol was compared with morphine, in dogs undergoing ovariohysterectomy or castration. The Glasgow composite measure pain scale-short form score (CMPS-SF) and changes in intraoperative electroencephalogram (EEG) responses were used to assess the efficacy of analgesics. Of the three treatment groups (preoperative morphine, 0.5 mg kg-1; preoperative tramadol, 3 mg kg-1; a ?combination? of preoperative low-dose morphine, 0.1 mg kg-1, and postoperative tramadol 3 mg kg-1), dogs given the ?combination? had significantly lower pain scores after ovariohysterectomy. In castrated dogs, preoperative tramadol (3 mg kg-1) and morphine (0.5 mg kg-1) were tested and no significant difference in the CMPS-SF score were observed between them. Changes in EEG variables were not specific between the treatment groups in ovariohysterectomised dogs. Finally, the efficacy of test drugs was evaluated against acute noxious electrical stimulation in anaesthetised dogs, using EEG. Median frequency of the EEG, a reliable indicator of nociception, increased significantly in tramadol and parecoxib groups, compared to morphine, after electrical stimulation. These studies demonstrated that tramadol and parecoxib can produce analgesia in dogs with insignificant side effects. The efficacy of tramadol appears to vary with the type of noxious stimulus. A complete prevention of noxious input by administration of analgesics pre- and post-operatively could have important clinical applications.

1. The aim of this research was to determine appropriate microbial indicator systems for use in monitoring the occurrence and source of faecal contamination in aquatic environments. Particular emphasis has been placed on the identification of indicators which might enable faecal contamination of human origin to be distinguished from that of non-human derivation. Two lines of investigation have been pursued; the use of alternative microbial indicator systems for water quality monitoring, and the development of diagnostic molecular methods for identifying the origin of faecal organisms. 2. Field and treatment plant studies were undertaken to investigate the utility of three indicator systems for monitoring water quality impacts in the coastal area surrounding the discharge from Auckland's North Shore City wastewater treatment plant. F-specific bacteriophage (F-phage) and ratios of F-phage to enterococci and faecal coliforms were examined over a twelve month period in which indicator levels at various stages of the wastewater treatment process were measured. These indicators and levels of Clostridium perfringens spores in sediment were measured in four outfall impact studies. 3. F-phage levels in effluent from the treatment plant (median=2.5 x 102 cfu/l00 ml) were too low to enable their use as source-specific tracers of effluent dispersion. However, higher F-phage levels in raw sewage (median=6.2 x l05 cfu/l00 ml) suggested that phage may be an appropriate indicator of raw sewage contamination in the receiving environment. F-phage was detected in coastal waters remote from the sewage outfall, providing presumptive evidence of sewage contamination entering the sea from sources other than the outfall discharge itself. 4. F-phage/enterococci and F-phage/faecal coliform ratios that were determined for sewage and treated effluent derived from the North Shore plant proved to be highly variable and were therefore unreliable for determining the source faecal contamination. 5. The concentration of Clostridium perfringens spores in sediments did not provide a useful means for tracing the distribution of faecal contaminants in the coastal system because the spore levels were found to be similar throughout the study area. This widespread occurrence of C. perfringens spores prevented identification of defined impact zones for any of the potential sources of faecal contaminants examined. 6. Randomly Amplified Polymorphic DNA (RAPD) analysis was used to investigate whether genetic markers could be identified for Escherichia coli isolates derived from different sources. RAPD profiling was found to be a highly discriminative method able to subtype E. coli strains present in both sewage and in the wastewater stream of a mechanical wood-pulping operation. In the pulp mill effluent, RAPD analysis indicated the presence of a restricted range of E. coli strains compared to the range found in the water intake and sewage effluent discharges. The results obtained provide presumptive evidence for the multiplication of E. coli strains within the wastewater stream. 7. Comparison of RAPD profiles derived from a range of human and environmental E. coli isolates led to the identification of a 1.6-kb marker. present in a subset of human isolates, but found only infrequently in isolates from animal origin. Primers based on sequence information obtained from this region of the genome yielded a direct PCR assay for the 'human' marker. The reliability and utility of the assay was improved when fluorescently-labelled primers and an automated DNA detection system was employed for the analysis of the amplified PCR products. 8. The diagnostic polymorphism was localised to the region immediately downstream of the gene encoding the glycine decarboxylase P-protein (gcvP). Comparison of DNA sequences from this region in 'marker-positive' and 'marker-negative' E. coli isolates revealed an abrupt loss of homology immediately downstream of the transcription termination point of the gcvP gene. The region of non-homology extends for at least 130 base pairs beyond the gcvP transcription terminator. Sequences spanning this region in marker-negative isolates exhibited a high level homology with that determined for E. coli K-12. The origin of the sequence for the same region in marker-positive isolates was unable to be identified. 9. The utility of the marker for environmental monitoring was investigated in a field study of a rural stream receiving bacterial contamination of both human and animal origin. The marker was consistently detected both in isolates derived from sewage effluents and in those found immediately downstream from sewage inputs-despite the presence of a high background of E. coli of animal origin. However the utility of the marker as a sewage-specific tracer was limited by the relatively low numbers of marker-positive d. coli in sewage effluents (approximately 8%). 10. In summary, the work described in this thesis has confirmed the need for multiple indicator systems in water quality monitoring and has identified appropriate areas for further research. The most promising area for future research is in the development of molecular tools which might provide both a better understanding of genetic variation in indicator organisms and enable methods to be developed for the detection of host-specific strains. Location of other polymorphisms likely to be present in the E. coli genome should enable further host-specific markers to be identified which could complement the 'human' marker identified in this study.

This study investigated whether behavioural and cognitive dysfunction caused by mucopolysaccharidosis (MPS) IIIA can be detected early in affected dogs’ lives, and to describe the behaviours of these dogs. No other scientific papers have been published on this topic and the population of dogs examined in this study are the only MPS IIIA affected dog colony available worldwide for study. Three main tests were performed on the population of MPS IIIA affected dogs. Physical behavioural assessment tests were performed at six and eight weeks of age and from twenty weeks of age a cognitive function task was taught and then tested to measure the dogs’ performance. A previously validated questionnaire, the canine behavioural assessment and research questionnaire (C-BARQ), was completed at three, six and twelve months of age. The researchers in these studies were blinded to the MPS IIIA status of the dogs examined. The behaviours shown by the MPS IIIA puppies at six and eight weeks of age were not significantly different from the behaviours of the unaffected puppies. This finding supported the research of other MPS IIIA studies and suggests that clinical behavioural changes do not occur at such a young age. The behaviours shown by the MPS IIIA affected puppies appeared to be normal puppy behaviours similar to those described in previous research on puppies. The C-BARQ measured the behaviours shown by the MPS IIIA affected and unaffected dogs. Most of the MPS IIIA affected dogs’ behaviours were not significantly different from the unaffected dogs’ behaviours, but MPS IIIA affected dogs did retrieve significantly more than unaffected dogs at three months of age, and were less distractible at twelve months of age. It would be worth investigating these findings further to decide whether it suggests a subtle alteration in brain functioning. The cognitive function test showed a significant decrease in the success of the MPS IIIA affected dogs in the final maze test. This is the first study on dogs affected with MPS IIIA to find a decline in cognitive function before the occurrence of cerebellar clinical signs and this new knowledge may lead to future developments measuring therapy response and disease progression. The T-shaped maze testing may be valuable in future research on cognitive function in dogs with other diseases such as epilepsy. Thus this thesis provides valuable information on canine MPS IIIA and provides a foundation for future disease investigations.

Maud Island (Te Hoiere - "a long paddle or mighty pull") is a moderately sized island of 309 hectares, located in the Pelorus Sound (41°, 02 'S, 173° 54 'E) Marlborough, at the north-east end of the South Island of New Zealand. It has a long history of human modification and impacts since its colonisation by Maori and early Europeans. The vegetation of Maud Island has been studied in the 1980's and again in the early 1990's. The objectives of this study were to (1) describe how the vascular plant communities vary in species composition across Maud Island, (2) determine which environmental factors are important predictors of the variation in species composition of Maud Island plant communities, and (3) describe the pattern of succession of the plant communities on Maud Island over the last twenty years. In this 2001 study, I comprehensively sampled the vegetation on Maud Island using a Reconnaissance Description Procedure in a total of 158 plots across the island and compared these results to previous descriptions. I also retook photos at permanent photo points to provide a visual comparison of vegetation change. In total, 219 plant species were identified; 177 species occurred within the plots and 42 additional species were observed while walking around the coastline and walking tracks. Six dominant plant species occurred in over 70% of the plots. They were Pteridium esculentum, Pseudopanax arboreus, Hebe stricta var. stricta, Melicytus ramiflorus, Ozothamnus leptophylla and Coprosma robusta. Two-Way Indicator Species Analysis resulted in the description of eight different plant communities on the island. Detrended correspondence analysis showed a high degree of turnover in species composition among these communities. Canonical correspondence analysis showed that slope and moisture were particularly important predictors of variation in plant species composition. The environmental factors that best predicted to variation communities were slope, moisture, and a gradient in historical disturbance. Comparisons of present and past vegetation maps and photos (ground and aerial) showed, in terms of the successional pathways of the vegetation on Maud Island, that over time, the vegetation is reverting from short stature grassland and scrub to predominantly forest scrub and young secondary forest.

Amphibians are suffering extinctions and range contractions globally. This is caused by numerous factors and most of them are related to human activities. The overall aim of this thesis was to make a significant contribution to the conservation of the endemic amphibian Leiopelma hochstetteri through research. This was achieved by focusing in two of the main conservation issues for this species, the need for standardised and robust monitoring techniques to detect trends and changes in populations, and the determination of the prevalence of chytridiomycosis, caused by the amphibian chytrid fungus (Batrachochytrium dendrobatidis). Two populations of the Auckland Region were selected for this study, one on the mainland (Waitakere Ranges) and the only known offshore island population of this species (Great Barrier Island). For both study sites different monitoring methods were used to obtain some population parameters. Site occupancy models of MacKenzie et al. (2002) gave reliable site-specific estimations of occupancy and detection probability using covariate information and presence-absence data collected from 50 sites in the Waitakere Ranges and four repeated visits during 2008. Elevation and distance searched were found to have an important effect on occupancy levels, while time taken to search the site was important variable determining detection probabilities. Also, parameters were estimated for three age classes separately. Statistical models were used to infer abundance from occupancy analysis, and results were compared with the distribution of relative abundances obtained from repeated transect counts and an established sight/re-sight criterion. In addition, the use of surrogate measures for relative abundance was explored. Detection probability and the distance to first frog found were found to have a significant correlation with relative abundance. These measures can be used to infer relative abundance in future site occupancy surveys. Two surveys and a pilot site occupancy survey were conducted on Great Barrier Island, and presence of frogs was confirmed atthe northern block, and in a small seepage in the central block. No new locations were found. Waitakere Ranges and Great Barrier Is. populations were tested for the presence of chytridiomycosis, and all frogs sampled tested negative (n = 124) which means that if present chytridiomycosis prevalence is lower than 5% with a 95% confidence interval. This and previous evidence suggests that L. hochstetteri may be resistant or immune to the disease. However, to confirm this additional studies are needed.

There is an extensive debate on the potential environmental impact of dairy farms and in particular the effect of dairy farms on the nitrogen cycle and the effect that this has on ecosystems. Within New Zealand and in particular in the South Island, the expansion of dairying and the adoption of new dairy systems has led to this becoming an increasingly important issue, locally through its effect on water quality and the environment and nationally and internationally through the production of green house gases. Increases in nitrogen usage at the expense of clover nitrogen fixation, irrigation, stocking rate and the introduction of dairy cows onto light free draining soils previously the preserve of arable or sheep farming has led to concern as to the effect intensive pastoral dairying may have on the nitrogen dynamics of the farm and the environment. This study is designed to assess how changes in grazing management in particular changes in pre-grazing and post-grazing residuals alter the clover/ryegrass balance on the farm and the effect that this has on the farm’s nitrogen dynamics. The effects of qualitative changes in grazing management on pasture composition are well established but little is known of the effect of quantitative changes in pasture management on composition, in particular the effect of grazing residuals. There are a number of detailed models of the physiological processes in the energy and nutrient cycling in plants, animals and the soil. There are a smaller number of whole farm models that through integration and simplification of component models attempt to represent the flux of nutrients though a dairy farm. None of these whole farm models is currently able to model the nitrogen flux through a dairy farm at a sufficient level of resolution to capture differences in pasture composition as these occur spatially, temporally and in response to grazing management. This project sought to better understand the nitrogen dynamics on a dairy farm by constructing and then linking component models – a pasture composition and growth model, a cow model, an excretal return model, a soil model and a water balance model – within a whole farm management schedule. The formal null hypothesis is that the mechanistic, mathematical model constructed for this PhD cannot capture and explain the full range of the changes in soil water content, soil nitrogen status, pasture production and composition and animal production, following the alteration in management of the dairy farm between 2002 and 2004. Individual component models were constructed by the author using the computer software package (Matlab) and validated against data extracted from the literature. The models were then converted into one simulation package using C-sharp as the source code language by Elizabeth Post, Senior Computer Scientist at Lincoln Ventures Ltd, Lincoln, New Zealand and the author. This model was then used to investigate the nitrogen dynamics of a dairy farm: the relationship with pasture composition and whether small changes in pasture residuals make a difference to pasture composition and nitrogen dynamics. Two different simulations were run based on the management practice of Lincoln University Dairy farm (LUDF) over two dairy seasons (2002-03 and 2003-04) and validated against the data recorded on this farm. In 2002-03, 50 cows were over wintered and 580 cows were subsequently milked on 200ha. Post grazing residuals where maintained at 1600-1750KgDM/ha. In 2003-04, 125 cows were overwintered and 635 cows were milked on 200ha with post grazing residuals maintained at 1400KgDm/ha. All models operate on a daily time step. Within the pasture model composition is described by 9 state variables describing different components of the pasture and pasture growth is modelled mechanistically from a calculation of component photosynthesis. A further 9 state variables describe the nitrogen composition of the pasture components. The soil model is a variable two layer, mechanistic representation, parametised for the shallow, stony soils of LUDF. Soil water status is an input for the pasture model while water uptake by the growing plants affects the soil water balance within the soil model. Animal intake and production are modelled mechanistically with model cows described in terms of their age, genetic merit, body weight, breed, pregnancy status, conception date and body condition score. Each cow type produces a different quantity of urinary and faecal excretion which varies with dry matter intake, milk yield and the sodium and potassium status of the pasture. Excretal nitrogen composition is predicted within a separate model which calculates daily nitrogen excretion in faeces, urine and milk. Excretions are deposited randomly over the grazed area and account is taken of overlapping excretions that are created on the same day and overlaps that occur with older excretal patches deposited in previous grazing rounds. Each excretal patch has its own associated pasture, water and soil model reflecting the differences in nitrogen status between patches. Grazing preference is expressed within the model between different classes of excretal patch and between excretal patches and the base pasture and between clover and grass. Supplementary silage is conserved and fed according to the management schedule of LUDF. Cows calve, become pregnant and are dried off within the model according to the relevant records from LUDF. Cows are deemed to arrive on the farm on the day of calving and to leave on the day that drying off is finished (a 5 day procedure within the model), except for those cows that are overwintering which remain on the farm. The soil model has multiple nitrogen/carbon pools and is dynamically linked to all the other models. External nitrogen losses from the system are modelled as volatilisation, leaching and denitrification, with pasture nitrogen uptake from the soil model and fixation by clover from the atmosphere. Both the individual component models and the final assembled composite model were successful in matching the available data in terms of pasture and animal production, pasture composition, soil water balance and nitrogen status and external losses. The model indicates that the low residual, high stocking rate farm returns more excreta to the soil. However, this is countered by a reduction in the amount of dead material returned to the paddock and this reduces the relative size of the pool of nitrogen in the dead organic matter. This produces a relative lack of substrate for the soil microbes which are thus unable to exploit all of the nitrogen in the available pool. Soil ammonium and nitrate pools are also increased from the increase in faecal and urinary return so precipitating an immobilising flux from these larger pools to the smaller pool of nitrogen available to the soil microbes. However, the relative inability of the soil bacteria to fully exploit this means that the production of soil organic live matter and the resulting mineralising flux from the dead organic matter pool through the available pool to the ammonium and nitrate pools is reduced. The larger ammonium and nitrate pools will also be associated with increased external losses from the system as denitrification, leaching and volatilisation are increased. The increase in the clover percentage within the sward in 2003-04 led to greater nitrogen fixation and the model suggests that some of the extra nitrogen is effectively captured by the animals in increased production. However, the reduction in the return of dead matter coupled with an increase in excretal return and the consequent increase in the mineral nitrogen pools within the soil lead to greater losses of nitrogen from the soil.

The article presents a brief retrospective of the experience of teaching the educational discipline "Zooculture" to students of the Veterinary and Biological Faculty of the Moscow Veterinary Academy (FSBEI V MGAVMiB - MBA named after K.I. Scriabin). This subject is extremely relevant in the system of higher veterinary and biological education, since it comprehensively examines the issues of animal cultivation in modern conditions of anthropogenic transformation of the environment. The theoretical basis of the course currently taught at the Faculty of Veterinary Biology is the work of scientists of the Academy Gabuzov O.S., Lebedev I.G., Alpatov V.V., Pimenov N.V., Lomskov M.A. The information of the educational discipline "Zooculture" contributes to the deepening of knowledge in the unified system of integrated veterinary and biological education and is consistent with classical and applied disciplines studied both before the beginning of the development of the considered educational course, and after. Also, in addition to analyzing the experience of teaching the discipline "Zooculture", the authors of the article indicate possible prospects for the development of the course under consideration, based primarily on modern genetic engineering methods of biotechnological science. Thus, "Zooculture", being an interdisciplinary educational course, combines theoretical knowledge of such biological disciplines as, for example, "Ecology and rational nature management", "Zoology", "General Biology" with relevant practical methods and skills of applied disciplines of veterinary and biological profile ("Fundamentals of Veterinary Medicine", "Genetics", "Model animals in biotechnology", "Applied immunology", etc.).
