Constraints in animal health service delivery and sustainable improvement alternatives in North Gondar, Ethiopia.

Poor livestock health services remain one of the main constraints to livestock production in many developing countries, including Ethiopia. A study was carried out in 11 districts of North Gondar, from December 2011 to September 2012, with the objective of identifying the existing status and constraints of animal health service delivery, and thus recommending possible alternatives for its sustainable improvement. Data were collected by using pre-tested questionnaires and focus group discussion. Findings revealed that 46.34% of the responding farmers had taken their animals to government veterinary clinics after initially trying treatments with local medication. More than 90.00% of the clinical cases were diagnosed solely on clinical signs or even history alone. The antibacterial drugs found in veterinary clinics were procaine penicillin (with or without streptomycin), oxytetracycline and sulphonamides, whilst albendazole, tetramisole and ivermectin were the only anthelmintics. A thermometer was the only clinical aid available in all clinics, whilst only nine (45.00%) clinics had a refrigerator. In the private sector, almost 95.00% were retail veterinary pharmacies and only 41.20% fulfilled the requirement criteria set. Professionals working in the government indicated the following problems: lack of incentives (70.00%), poor management and lack of awareness (60.00%) and inadequate budget (40.00%). For farmers, the most frequent problems were failure of private practitioners to adhere to ethical procedures (74.00%) and lack of knowledge of animal diseases and physical distance from the service centre (50.00%). Of all responding farmers, 58.54% preferred the government service, 21.14% liked both services equally and 20.33% preferred the private service. Farmers' indiscriminate use of drugs from the black market (23.00%) was also mentioned as a problem by private practitioners. Sustainable improvement of animal health service delivery needs increased awareness for all stakeholders and a well-regulated private service in order to mitigate the constraints apparent in the government service.

Description of the pig production systems, biosecurity practices and herd health providers in two provinces with high swine density in the Philippines

A cross-sectional study was conducted between October 2011 and March 2012 in two major pig producing provinces in the Philippines. Four hundred and seventy one pig farms slaughtering finisher pigs at government operated abattoirs participated in this study. The objectives of this study were to group: (a) smallholder (S) and commercial (C) production systems into patterns according to their herd health providers (HHPs), and obtain descriptive information about the grouped S and C production systems; and (b) identify key HHPs within each production system using social network analysis. On-farm veterinarians, private consultants, pharmaceutical company representatives, government veterinarians, livestock and agricultural technicians, and agricultural supply stores were found to be actively interacting with pig farmers. Four clusters were identified based on production system and their choice of HHPs. Differences in management and biosecurity practices were found between S and C clusters. Private HHPs provided a service to larger C and some larger S farms, and have little or no interaction with the other HHPs. Government HHPs provided herd health service mainly to S farms and small C farms. Agricultural supply stores were identified as a dominant solitary HHP and provided herd health services to the majority of farmers. Increased knowledge of the routine management and biosecurity practices of S and C farmers and the key HHPs that are likely to be associated with those practices would be of value as this information could be used to inform a risk-based approach to disease surveillance and control.

Cattle movements and trypanosomes: restocking efforts and the spread of Trypanosoma brucei rhodesiense sleeping sickness in post-conflict Uganda

BackgroundThe northwards spread of acute T. b. rhodesiense sleeping sickness in Uganda has been linked to cattle movements associated with restocking following the end to military conflict in 2006. This study examined the number of cattle traded from T. b. rhodesiense endemic districts, the prevalence of the parasite in cattle being traded and the level of trypanocidal treatment at livestock markets.MethodsBetween 2008 and 2009 interviews were carried out with government veterinarians from 20 districts in Uganda, 18 restocking organisations and numerous livestock traders and veterinarians. Direct observations, a review of movement permit records (2006 to 2008) and blood sampling of cattle (n = 1758) for detection of parasites were also conducted at 10 livestock markets in T. b. rhodesiense endemic districts.ResultsRecords available from 8 out of 47 identified markets showed that 39.5% (5,238/13,267) of the inter-district cattle trade between mid-2006 and mid-2008 involved movement from endemic areas to pathogen-free districts. PCR analysis showed a prevalence of 17.5% T. brucei s.l. (n = 307/1758 [95% CI: 15.7-19.2]) and 1.5% T. b. rhodesiense (n = 26/1758 [95% CI: 0.9-2.0]) from these same markets. In a two-year period, between late-2006 to late-2008, an estimated 72,321 to 86,785 cattle (57, 857 by 18 restocking organisations and 10,214 to 24,679 by private traders) were imported into seven pathogen-free northern districts, including districts that were endemic for T. b. gambiense. Between 281 and 1,302 of these cattle were likely to have carried T. b. rhodesiense. While governmental organisations predominantly adhered to trypanocidal treatment, most Non-Governmental Organisations (NGOs) and private traders did not. Inadequate market infrastructure, poor awareness, the need for payment for drug treatments, and the difficulty in enforcing a policy of treatment at point of sale contributed to non-compliance.ConclusionWith increasing private trade, preventing the spread of Rhodesian sleeping sickness in Uganda requires government support to ensure mandatory trypanocidal treatment at livestock markets, investment in market infrastructure and possible drug subsidy. Mapping the northern reaches of T. b. rhodesiense in livestock and preparation of risk assessments for cattle trading could mitigate future outbreaks.

Challenges to quality testing for bovine tuberculosis in Ireland; perspectives from major stakeholders

Within the national bovine tuberculosis (bTB) eradication programme in Ireland, concern has been expressed about the quality of testing by veterinarians. However, there is little published evidence supporting this concern,...

Dog bite histories and response to incidents in canine rabies-enzootic KwaZulu-Natal, South Africa.

The objective of this paper is to report evaluated observations from survey records captured through a cross-sectional observational study regarding canine populations and dog owners in rabies enzootic KwaZulu-Natal province, South Africa. Our aim was to evaluate respondent knowledge of canine rabies and response to dog bite incidents towards improved rabies control. Six communities consisting of three land use types were randomly sampled from September 2009 to January 2011, using a cluster design. A total of 1992 household records were analyzed using descriptive statistics and regression modeling to evaluate source of rabies knowledge, experiences with dog bites, and factors affecting treatment received within respective households that occurred within the 365 day period prior to the surveys. 86% of the population surveyed had heard of rabies. Non-dog owners were 1.6 times more likely to have heard of rabies than dog owners; however, fear of rabies was not a reason for not owning a dog. Government veterinary services were reported most frequently as respondent source of rabies knowledge. Nearly 13% of households had a member bitten by a dog within the year prior to the surveys with 82% of the victims visiting a clinic as a response to the bite. 35% of these clinic visitors received at least one rabies vaccination. Regression modeling determined that the only response variable that significantly reflected the likelihood of a patient receiving rabies vaccination or not was the term for the area surveyed. Overall the survey showed that most respondents have heard of dog associated rabies and seek medical assistance at a clinic in response to a dog bite regardless of offending dog identification. An in-depth study involving factors associated within area clinics may highlight the area dependency for patients receiving rabies post exposure prophylaxis shown by this model.

Factors influencing choice of veterinary service provider by pastoralist in Kenya

This study analyzed the determinants for choice of animal health providers in a semiarid pastoral area with an aim of identifying specific attributes that could be targeted for intervention to enhance pastoralist access to quality veterinary services. The data were collected through administration of semi-structured questionnaires to 350 randomly selected household heads in different locations in Narok County of Kenya. Most of these respondents had no formal education (66.9%), and most households were headed by men (88.9%). The men were in control of sales (84.2%), purchases (83.7%), and treatment of sick cattle (70.3%), while women were responsible for milking (83.8%). Animal health services were delivered by drug stockists (87.76%) and government veterinarians (12.24%). The time spent while seeking animal health services and transport cost were specific attributes with impact on the probability of choice for service providers. Although distance covered to the preferred service provider was a significant attribute, it was inversely related to the probability of choice. The other factors including herd sizes, age and sex of household head, cost incurred per visit, level of education of household head, and the number of visits did not have significant impact on choices. These findings support commercialization of veterinary services in marginalized areas where the delivery of essential animal health services such as disease control programs are often viewed as a public good. In order to enhance delivery of veterinary services in these areas, it is proposed that public and private means are investigated to support qualified veterinarians and to strengthen the activities of untrained personnel operating drug outlets.

Veterinarian challenges to providing a multi-agency response to farm animal welfare problems in Ireland: responding to the human factor.

In 2012, the authors undertook a study of the challenges facing government and private veterinarians in responding to the human element of farm animal welfare incidents (i.e. the personal problems and difficulties of farmers that can result in farm animal neglect). This paper reports their findings and examines the role of veterinarians in responding to the difficulties of farmers. It also looks at their experiences of attempting to build a multi-agency approach involving veterinary and human support services. This paper builds on a study whereby the authors considered how social, health and attitudinal factors, as well as mental health problems, contribute to farm animal welfare incidents in Ireland. An early warning system involving relevant agencies is in place to identify and prevent farm animal welfare problems before they become critical. The literature provides examples of private veterinarians combining with support services where there are indicators of animal and human abuse. Yet there are no research examples of government or private veterinarians linking with support services to resolve farm animal welfare cases where there are social, health, and/or mental health difficulties with the herd owner. Four focus groups were conducted with government veterinarians (n = 18) and three with private veterinarians (n = 12). Government veterinarians made contact with support services to seek advice on how best to respond to the human element of farm animal welfare incidents, and/or to seek support for the herd owner. Contact between government and private veterinarians was driven by the former. Communication between agencies was influenced by individual efforts and personal contacts. Formal structures and guidelines, perceived professional capabilities in determining herd owner needs, and client confidentiality concerns among support services and private veterinarians were less influential. The fear of losing clients and the financial implications of this were also cited by private veterinarians. Family, neighbours and local support groups assisted in reaching an on-farm solution. The paper concludes with the requirements for a multi-agency approach in Ireland: the provision of tailored information and guidelines targeting government and private veterinarians and support services, and a comprehensive structure for relationship-building, planning, and cross-reporting between all the relevant agencies.

Anthelmintic utilisation practices and prevalence of gastrointestinal helminth infections in sheep kept in the urban and peri-urban areas of Bishoftu Town

Assessment of the anthelmintic (AH) utilisation practices and estimation of the prevalence of gastrointestinal helminth infections in sheep were carried out from November 2010 to April 2011 in urban and peri-urban areas of Bishoftu Town, central Ethiopia. A structured questionnaire was employed to assess the AH utilisation practices in sheep of 310 owners/households, while floatation and sedimentation techniques were used to study the prevalence of helminth infections. Faecal examinations revealed that 53.9 % of sheep harboured gastrointestinal helminth infections with a high frequency due to strongyles (77.3 %). The questionnaire survey revealed that sources of AH for sheep were government and private veterinary clinics for 98.5 % of urban and 65.4 % peri-urban respondents. In peri-urban areas, AH were also purchased from open markets and illegal dealers. Albendazole was the most common (75.5 %) drug used in sheep followed by ivermectin (18.7 %) and tetramisole (5.8 %). The criteria for selecting AH were: prescription by veterinarians (51.6 %), efficacy (31.9 %), price (12.3 %) and arbitrary reasons (4.2 %). Treatment frequency was minimal with 51.3, 32.3 and 15.8 % of the owners treating their sheep once, twice and less than once per year, respectively. Treatments mainly depended on manifestations of general (45.8 %) and digestive (23.3 %) symptoms. Irrespective of the body weight of the sheep, albendazole was the only drug reported to be given at half bolus/sheep (14.1 %). Owing to this practice, albendazole faces the risk of reduced efficacy or AH resistance due to its wide spread utilisation, handling by untrained personnel and suspected underdosage, which altogether support the perception of sheep owners on its lower effect on the performance of treated sheep.

ANATOMICAL STUDY OF THE TONGUE OF INDIGENOUS COW (BOS INDICUS) IN BANGLADESH WITH SPECIAL EMPHASIS ON PAPILLAE DISTRIBUTION

The present study was conducted on the tongue of six apparently healthy indigenous (Bos indicus) cows of different age and sex and they were collected from local market at Dinajpur district and this research work was conducted in the Department of Anatomy and Histology, Dinajpur Government Veterinary College, Dinajpur during the research period from the month of July 2003 to April 2004. After proper euthanasia, the animals were killed and then the tongues of these animals were dissected out from the carcasses and fixed in 10% neutral buffered formalin solution. In the present study it was observed that the tongue of indigenous cow (Bos indicus) of Bangladesh has three parts: the root, body and an apex. The dorsum linguae was specially more pronounced in its centre and was occupied by numerous types of masticatory and gustatory papillae. The fine rasp-like filiform papillae were more numerous and directed caudally throughout the dorsum and packed closely in front of the fossa linguae throughout the tip, whereas, the club shaped fungi form papillae were irregularly distributed all over the dorsum among the filiform papillae. The broad headed lentil shaped lenticular papillae was also found in the rostral two-thirds of the dorsum but better developed along the mid-line of the tongue. The large conical papillae of the tongue of Bos indicus occurred in the rostral two-thirds of the dorsum with a higher concentration in the middle portion of the tongue, however, the small ones occurred through out the torus. The vallate papillae of the tongue of Bos indicus were 12-20 in number on either side and dispersed in two irregular rows (25-40) in total along the caudolateral two-thirds of the dorsum. The mucosa of the root of the tongue of Bos indicus did not show any specific papillae but it was rather smooth due to diffused lymphoid tissue distribution (lingual tonsil).

HAEMATOLOGICAL PICTURES IN CLINICALLY AFFECTED DOGS

Haematological examination was carried out on 23 clinically affected dogs with various diseases or conditions at Teaching Veterinary Hospital of Chittagong Government Veterinary College for a period of 5 months from July to November 2003. On haematolo-ical examination, total erythrocyte count, haemoglobin concentration and packed cell volume were recorded to be normal in dog irrespective of types of breed except anaemia. Decreased haematological values (TEC 2.1-2.5 million / cmm, Hb 3.4-5 g% and PCV 12-13%) were recorded in anaemic cases. The elevated erythrocyte sedimentation rate was recorded in maximum cases of dog. However, higher leukocyte count (19-26.7 thousand / cmm) was recorded in dermatitis, mammary tumor, abscess and leptospirosis of dogs. On differential leucocyte count, lymphocytes and eosinophils were counted higher while neutrophils were counted lower in dermatitis of German Shepherd and local breeds. Alarming lower percentage of lymphocytes (12-13%) and higher percentage of neutrophil (70-72%) and monocyte (9-10%) were registerd in leptospirosis. On the other hand, lymphocytes count in fever (40-58%), conjunctivitis (54%) and fracture (46%) were higher while lower percentage of neutrophil was recorded as 35-54%, 36% and 52% respectively in Shamoyed breed.

The Recognition Lecture is an annual honor awarded by the Association of American Veterinary Medical Colleges (AAVMC) to an individual whose leadership and vision have made significant contributions to academic veterinary medicine and the veterinary profession. In 2011, this prestigious honor was awarded to Dr. Peter Eyre, Dean Emeritus of the Virginia-Maryland Regional College of Veterinary Medicine (VMRCVM). Dr. Eyre is a fierce advocate for veterinary medical education, with a clear vision of its value in ensuring that veterinarians are well positioned to meet societal needs. Dr. Eyre possesses an international perspective regarding the challenges and problems facing veterinary medical education and has a keen eye for getting to the heart of these challenges. He is known to ask hard questions and propose difficult choices. Dr. Eyre received his undergraduate veterinary degree (BVMS), bachelor of science degree, and PhD from the University of Edinburgh. He was Lecturer in Pharmacology at the Royal (Dick) School of Veterinary Studies for seven years before joining the faculty of the University of Guelph's Ontario Veterinary College, where he was Chair of the Department of Biomedical Sciences and Associate Director of the Canadian Centre for Toxicology. Dr. Eyre was appointed Dean of the VMRCVM in 1985, where he established the Center for Government and Corporate Veterinary Medicine in 1989. After retiring in 2003, he was named Interim Dean of the University of Calgary's new veterinary school. Among his many awards are the Norden Distinguished Teacher Award and the Sigma Psi Excellence in Research Award. In 2008 the American Veterinary Medical Association (AVMA) honored him with the President's Award, and in 2010 the University of Edinburgh awarded him the honorary degree of Doctor of Veterinary Medicine and Surgery. The Peter Eyre Student Leadership Award at the VMRCVM and the Peter Eyre Prize in Pharmacology at the University of Guelph are both named in his honor. He is a past president of the AAVMC, a fellow and former board member of the American Academy of Veterinary Pharmacology and Therapeutics, and a former member of the AVMA Legislative Advisory Committee. In the following article, Dr. Eyre offers his insights on the current debate about the future of veterinary medical education.

Quantifying Experts’ Uncertainty About the Future Cost of Exotic Diseases

Since the foot-and-mouth disease outbreak of 2001 in the United Kingdom, there has been debate about the sharing, between government and industry, both the costs of livestock disease outbreaks and responsibility for the decisions that give rise to them. As part of a consultation into the formation of a new body to manage livestock diseases, government veterinarians and economists produced estimates of the average annual costs for a number of exotic infectious diseases. In this article, we demonstrate how the government experts were helped to quantify their uncertainties about the cost estimates using formal expert elicitation techniques. This has enabled the decisionmakers to have a greater appreciation of government experts' uncertainty in this policy area.

Veterinary education in South Africa : the classes of 1938 and 1939 : historical article

Concise descriptions are given of the life histories of the 10 members of the classes of 1938 and 1939. All of them initially joined the government service, Hugo, Steenekamp and Schatz spending their entire careers in the South African Veterinary (Field) Services. Mansvelt, the first recipient of the much-coveted Theiler medal, was the 2nd veterinarian to be appointed Director of Veterinary Services, a position specially created for the 'Field' in 1962. Having first established a successful private practice, Hofmeyr was appointed as the 1st full-time Professor of Surgery of the Onderstepoort Faculty in 1958 and its 1st full-time Dean in 1976. Albertyn opted for a career in public health, becoming director of 1 of the largest local municipal abattoirs. Turner spent virtually his entire career in private practice and was eventually joined by Brown who had served in the British Colonial Veterinary Service for many years. Fick was a government veterinarian for his entire career, first in South Africa, then in the British Colonial Service (for 13 years) and finally returning to South Africa. Like Hugo, Muller filled a senior position in Veterinary (Field) Services before he opted for a farming career.

Carriage of methicillin‐resistant Staphylococcus aureus by veterinarians in Australia

To estimate the prevalence of carriage of methicillin-resistant Staphylococcus aureus (MRSA) among Australian veterinarians. Individuals attending veterinary conferences in Australia in 2009 were recruited to provide nasal swabs and complete a questionnaire about their professional activities. Swabs were processed by standard methods for detecting MRSA and questionnaire responses were used to group veterinarians according to their areas of major work emphasis (species and practice type). Prevalence was estimated for each of these grouping and contingency tables and regression tree analysis used to explain the variation in MRSA carriage. Among the 771 respondents 'industry and government veterinarians' (controls) had the lowest prevalence of MRSA carriage at 0.9%. Veterinarians with horses as a major area of work emphasis had a prevalence of 11.8% (13-fold that of controls) and those whose only major emphasis was horses had a prevalence of 21.4% (23-fold that of controls). Veterinarians with dogs and cats as a major activity had a 4.9% prevalence (5-fold that of controls). Prevalence rates for other major activities (pigs, dairy and beef cattle, avian and wildlife) were also increased, but were estimated from smaller numbers of respondents. Regression tree analysis clearly isolated equine veterinarians and dog and cat practitioners as groups at increased risk of carriage of MRSA. Carriage of MRSA is a notable occupational health issue for veterinarians in clinical practice in Australia, particularly those who work with horses.

Essential veterinary education in the governance of public Veterinary Services

A comprehensive understanding of the national and international governance of animal health and Veterinary Services must be part of the professional culture of all veterinarians. This includes, in particular, understanding the scope of public (government or national) Veterinary Services within the meaning of the World Organisation for Animal Health standards, the societal importance of the missions of such public Veterinary Services, the history of their structure, and their involvement in animal health, animal welfare, essential protein supply, etc. The quality standards of a national Veterinary Service must be placed within the context of the actual situation in a specific country. Knowing the key elements of international governance implies studying the new global context of animal health services, the international organisations competent to supervise them, and the legal and economic aspects of this arena. In addition, special training is recommended for veterinarians recruited by public Veterinary Services.

Molecular genetic analysis of populations of Wohlfahrt’s wound myiasis fly, Wohlfahrtia magnifica, in outbreak populations from Greece and Morocco

Wohlfahrt's wound myiasis fly, Wohlfahrtia magnifica (Schiner) (Diptera: Sarcophagidae), is the most important cause of traumatic myiasis in the southern Palaearctic region. Larval stages are obligate parasites and the wounds caused by infestations are very similar to those caused by Old and New World screwworm flies. During the last decade, W. magnifica appears to have expanded its range to parts of northern and central Morocco, and to Crete, Greece. Specimens of W. magnifica were collected in Morocco and Crete either as larvae (preserved in 80% ethanol) or as adults (dry-pinned). Comparison specimens were collected in Spain, Hungary and mainland Greece. A DNA fragment containing the 3' 715 base pairs of the mitochondrial cytochrome b gene was amplified by polymerase chain reaction from each of 132 larvae or adults of W. magnifica and the amplicons were directly sequenced and analysed phylogeographically. Twelve cytochrome b haplotypes were detected. All haplotypes from Morocco belonged to a lineage that included specimens from the Iberian peninsula, and restricted mixing of central and northern populations in Morocco was demonstrated. Cytochrome b haplotyping combined with an analysis of larval size provided clear evidence of multiple infestations of hosts in all geographical areas, with one quarter of wounds containing larvae from two to at least four females. More than 80% of specimens from Crete contained a haplotype predominating in mainland Greece and Hungary. Our survey indicated that wohlfahrtiosis was more widespread in northern and central Morocco than previously recorded by government veterinarians. However, the prevalence of wohlfahrtiosis was low (< 1%). The high genetic diversity of Moroccan populations is consistent with longterm endemicity, rather than recent introduction. Crete showed a higher prevalence of wohlfahrtiosis (< or = 15%) and less genetic diversity of W. magnifica, which is consistent with a recent introduction. The western and eastern Mediterranean lineages may have been isolated in different Pleistocene ice-age refugia, from which there has been limited post-glacial dispersal.

The laboratory network in Australia and New Zealand – an evolving system

This paper discusses the network of government, private and university veterinary laboratories in Australia and New Zealand and how it is adapting and evolving to meet the challenges it faces. It includes the mechanisms for standardisation of procedures, quality assurance, and the role of national reference laboratories hosted by state government laboratories. It also highlights the crisis in supply of veterinary diagnosticians, especially the declining numbers of veterinary pathologists. Recent positive changes include the setting up of the National Animal Health Laboratory Strategy and an initiative to empower State and Territory government laboratories to test for exotic diseases. The ideal outcome for Australia and New Zealand is a laboratory service that remains the gold standard around the world.

Analysis of Pan-European attitudes to the eradication and control of bovine viral diarrhoea

At present, national-level policies concerning the eradication and control of bovine viral diarrhoea (BVD) differ widely across Europe. Some Scandinavian countries have enacted strong regulatory frameworks to eradicate the disease,...

Rural veterinary services in Western Australia: Part A. Government veterinary services

To determine the status of rural veterinary services in Western Australia. Two questionnaires were mailed to eligible, registered veterinary surgeons in Western Australia in 2006. The first was mailed to government veterinarians and the second to private practitioners in rural practice. Part A presents the replies from government veterinary officers and Part B the replies from rural practitioners. Replies were transferred to Microsoft Excel for analysis. Sixty-seven per cent of government veterinary officers responded to the questionnaire. Eighty per cent of these had been in the service for 20 years or more and their average age was 54. Work with sheep and beef cattle occupied 75% of their time, with dairy cattle receiving 10% and pigs and poultry less than 10%. The majority of respondents reported changes in the attitude of farmers to the service as a result of rural recessions and the decision to make a direct charge for government veterinary services. Although most respondents thought that the government veterinary service would continue in the future there were differences of opinion as to what form that would take. Government veterinary services in Western Australia are undergoing major changes, with the service decreasing in size and scope. Recently the Department of Agriculture has been renamed the Department of Agriculture and Food and it is likely that the role of its veterinary officers will change accordingly.
