Evaluation of cattle farmers' knowledge, attitudes, and practices regarding antimicrobial use and antimicrobial resistance in Rwanda.

The misuse of antimicrobials in livestock may lead to the emergence and spread of resistant pathogens harmful to human, animal, and environmental health. Therefore, determining the behavior and practices of farmers regarding antimicrobial use (AMU) and antimicrobial resistance (AMR) is crucial for addressing the growing threat of AMR. This cross-sectional study was conducted in the Eastern Province of Rwanda on 441 participants using a structured questionnaire to determine the knowledge, attitudes, and practices (KAP) towards AMU and AMR. Frequency distributions, chi-square test of association and logistic regression model were used to analyze the data. This study showed poor biosecurity measures at the farm level with various antimicrobials used here; 83.9% of participants obtained them from friends and neighbors and 61.9% used them for growth promotion. Our assessment revealed a low level of KAP towards AMR among cattle farmers from the study districts. Our data showed that at a 69% cutoff, only 52.6% of farmers had correct knowledge, whereas 56% had good attitudes (47% cutoff). Finally, 52.8% had correct practices toward AMR based on a calculated cutoff of 50%. Positive attitudes, correct knowledge, and practices regarding AMU and AMR were associated with higher educational levels. Sex was correlated with knowledge and attitudes, whereas farm location was associated with attitudes and practices. Farmers expressed a need for more access to veterinary services and AMR-related training for themselves, the community animal health workers, and veterinarians. This study highlighted the low levels of KAP associated with using antimicrobials, which may lead to the misuse of antimicrobials and the spread of AMR. It is imperative to develop and implement cross-cutting measures to minimize antibiotic usage and reduce the risk of antibiotic resistance.

Factors Influencing Smallholder Farmers’ Preference for Veterinary Service Providers in Zimbabwe

Animal diseases pose significant challenges to livestock production in Zimbabwe's smallholder sector. This study analyzed the variables influencing smallholder farmers' preferences for veterinary service providers. Data from a mixed-method approach, including a questionnaire (N=382), focus group discussions (N=8), interviews (N=16), and observations, were analyzed using descriptive statistics and multivariate probit regression. The findings revealed that access to veterinary services is complex and context-dependent, influenced by factors such as experiences, age, proximity to the provider, communication, remittances, satisfaction, repeat treatments, socioeconomic status, historical dynamics, and access to subsidized drugs. Government veterinary services, private sector entities, and Community Animal Health Workers played critical roles in the provision of veterinary services. Better coordination among the different service provides could enable provision of cost-effective services. The study highlights the multifaceted nature of smallholder farmers' decision-making, emphasizing the importance of situational factors and collaboration among service providers to meet their diverse needs effectively. These insights inform policymakers and stakeholders in developing strategies to enhance veterinary services in Zimbabwe's smallholder communities, ultimately improving livestock productivity and welfare.

Prevalence of cattle ixodid ticks and acaricides efficacy evaluation in Amibara district of Afar Region, Ethiopia.

A cross sectional and randomized controlled trial study was conducted starting from July 2021 to July 2022 to determine the prevalence of ixodid ticks, and evaluate the efficacy of commonly used acaricides (amitraz 12.5% and diazinon 60%) in vitro and in vivo on cattle ticks in Amibara district. A total of 372 cattle were visited randomly from six kebeles of the district which were selected based on their livestock population. A total of 4330 adult ticks were collected and identified to the species level with stereomicroscope. For the invitro acaricide efficacy test, 90 engorged female ticks were collected from infested herds and grouped into three, each group having ten engorged ticks; two groups for the two test acaricides and the third groups were control to evaluate these acaricides in the laboratory. All the groups were replicated three times and incubated for seven days with similar temperature and humidity. Thirty-six infested cattle were selected and again grouped into three randomly, 12 each for the invivo test. The first groups of animals were sprayed with amitraz, the second with diazinon and the third groups were left untreated. Ticks were counted and recorded before, day 3, day 7, day 14 and day 21 of spraying. A total of 360 (96.7%) of the visited cattle were infested with ticks. Amblyomma. Rhipicephallus, Hyalomma and Bophillus were the genera of ticks identified with a prevalence of 44.9%, 41.4%, 7.5% and 6.2% respectively. A total of 15 species of ixodid ticks were identified from which Rhipicephallus pulchellus (39.86%) was dominant followed by Amblyomma lepidum (26.65%) and Amblyomma gemma (14.36%). Diazinon 60% EC and amitraz 12.5% were significantly inhibited the egg laying ability of engorged ticks' in vitro with percent inhibition of 100% and 99.1% respectively. On live animal, both acaricides showed statistically significant difference from the control group (p- value <0.05) with maximum 97.37% (amitraz) and 93.33% (diazinon) at day 7 and minimum 73.3% (amitraz) and 73.7% (diazinon) efficacy. However, there was no statistically significant difference on egg laying inhibition and tick count reduction between the two acaricides (p-value >0.05). Therefore, awareness should be created about the high prevalence as well as the application, dosage and dilution of the acaricides to pastoralists, community animal health workers and para veterinarians in the study area. Cattle owners, veterinarians and concerned government officials should address infested herds with manufacturer recommended dosage of these acaricides to control the tick infestation.

Operationalizing a community-based One Health surveillance and response in Adadle district of Ethiopia

Abstract Surveillance of human and animal health is often carried out separately worldwide, which leads to the under-reporting of zoonotic and emerging diseases. Early cross-information between wildlife, domestic animal and public health sectors may reduce both exposure and cost of outbreaks. We have assessed the feasibility of a One Health Surveillance and Response System (OHSRS) in the Adadle district of Ethiopia in the Somali Region (SRS), with regard to integration into the existing regional surveillance-response system in the Somali Region of Ethiopia (SRS). To meet the objectives of a surveillance-response system, we established a One Health Surveillance and Response Unit (OHSRU) at the district level. Community Animal Health Workers, Community Health Workers (CHWs), and both human and animal health district staff and regional experts were trained together on the OHSRS. An inception workshop was held with all relevant stakeholders. To ensure the active engagement of communities in the surveillance response system, a Community-Based Emergency Fund (CBEF) and CAHW cost recovery mechanisms were established. All public and animal health staff of different administration levels were linked together. Human and animal health information was collected and shared effectively among sectors. This approach helped bridging the physical separation between the public and animal health sectors in disease surveillance in the Adadle district. Joint interventions, such as disease outbreak investigations and community awareness were initiated by the OHSRU. We demonstrated that the OHSR was successfully operationalized in Adadle districts and contributed to improving the early detection and response of zoonotic diseases. However, technical barriers, cost-effectiveness, legality of data and ethical safeguarding, along with political commitment should be addressed to effectively operationalize the OHSR in the whole region. Designing the OHSR through the existing surveillance system, engaging communities and other relevant sectors using a participatory process is an important contribution to a sustainable OHSR. One Health Impact Statement In this research work, the public and animal health sectors collaborated in data collection and initiated joint interventions. By integrating the surveillance operational costs for disease outbreak investigation and cost of public health associated with zoonotic diseases can be reduced as One Health surveillance and response lead to early detection and response to zoonotic diseases. As one health is collaborative efforts multispectral, multidisciplinary and transdisciplinary, i.e. involvement of all relevant sectors including community members and different disciplines in the launching workshop of surveillance system helped to define and agree the role of each sectors or partner’s in the One Health approach. This played a curtail role in the success of the approach. Lessons learned from this work can be used for further improvement in One Health approach in different settings.

Study on Prevalence of Ixodid Ticks of Goats and Acaricide Utilization Practices of Herd Owners in Benatsemay District, South Omo Zone, South-Western Ethiopia.

IntroductionTicks are major health problems of goats that contribute to a significant economic loss in Ethiopia.MethodsA cross-sectional study using a systematic random sampling technique was conducted to determine the prevalence, potential risk factors of hard ticks (Acarina: Ixodidae) of goats, and the acaricide utilization practice of herd owners in the Benatsemay district.ResultsOut of 285 examined goats, 85.26% of goats were found infested by Rhipicephalus and Amblyomma tick genera. The body condition score of goats was the only factor that was significantly (p < 0.05) associated with tick infestations. The frequently identified tick species were Rhipicephalus pulchellus (14.38%), Rh. decoloratus (11.22%), A. cohaerens (5.26%) and A. variegatum (4.21%), and mixed infestation (38.59%). Herd owner’s questionnaire survey revealed that 100% of interviewees responded that tick infestations were frequently encountered throughout the year and prevailed on aged goats (90%) and dry season (60%). Concurrent usage of ethnomedicinal plants and conventional acaricides were dominant practices to control tick infestation as responded by 60% of interviewees. Among the conventional acaricides, Diazinon and Ivermectin were the most practiced acaricides as replied by 90% of the respondents. Moreover, community animal health workers (CAHWs) (43.33%) and owners themselves (33.33%) were primarily responsible for acaricide application to tick-infested animals. About 66.67% of the livestock owner’s responses also disclosed that diazinon was the most effective acaricide followed by ivermectin (16.67%) and amitraz (6.67%). Finally, 56.57% of the respondents replied that acaricidal drugs from private veterinary drug shops were overpriced than the same acaricides from government veterinary clinics.ConclusionIn this study, there was a high prevalence of hard ticks in goats, and irrational application of acaricides was noted in the Benatsemay district; thus, appropriate tick control measures should be taken to minimize tick burden through using acaricides.

Veterinary Healthcare Provision and Quality of Reported Data on Antimicrobial Use in the Treatment of Livestock in Sierra Leone, 2016-2019.

Antimicrobials help in the prevention and treatment of infections and are crucial for animal production, but overuse can result in antimicrobial resistance. Hence, understanding data quality on livestock antimicrobial use is essential. We assessed frequency of reporting, completeness, and concordance of reported data and availability of human resources and infrastructure in 14 districts in Sierra Leone. This was a cross-sectional study involving a review of district and sub-district animal treatment forms submitted from January 2016 to August 2019. Out of the 14 districts, only 3 had filled forms available for review: A total of 6 (0.97% of 616 expected) district forms and 79 (1.15% of 6840 expected) sub-district forms. Data between district and sub-district treatment forms were fully discordant. Hence, completeness of data could not be assessed. All districts had livestock officers (barring one) and livestock assistants but no veterinarians. The gap in community animal health workers ranged from 14 to 100% per district. No districts had a functional computer or internet access. Reporting was non-existent in 11 districts and poor in the other 3. Resources are urgently needed to address critical gaps in human resources and capacity and computer and Internet connectivity to develop critical One Health surveillance functions at the national and sub-national levels.

Biosecurity in endemic foot and mouth disease settings: a case study of foot and mouth disease vaccination in South-East Asia.

Foot and mouth disease (FMD) is a highly contagious viral infection affecting cloven-hoofed animals including cattle, buffalo, sheep, goats and pigs. The disease is endemic in several parts of Asia, as well as most of Africa and the Middle East. In 1997, the World Organisation for Animal Health (OIE) established the South-East Asia Foot and Mouth Disease Campaign with the aim of increasing livestock sector productivity and economic output through the control and eradication of FMD in South-East Asia. Large-scale vaccination of livestock against FMD has in the past led to the successful eradication (or control) of the disease, for example in the Philippines. However, despite the benefit associated with large-scale vaccination, biosecurity risks can be created by vaccination teams moving between locations. It is therefore recommended that biosecurity measures are used by vaccination teams to prevent inadvertent disease spread. The majority of existing guidelines are focused on high-risk situations such as exotic animal disease outbreaks in developed countries, or agents posing a risk to human health. This paper describes the development of novel biosecurity guidelines for vaccination teams in South-East Asia. To achieve this, available literature was scanned followed by in-country workshops and field-testing of draft materials. Entry and exit procedures are laid out within the context of five core rules that follow the biosecurity principles of situational awareness, segregation, cleaning and disinfection. Guidelines and accompanying fact sheets were translated into local languages and included in a comprehensive vaccination training programme for all vaccination teams undertaking cattle FMD vaccination programmes in the New Zealand OIE FMD control project target countries (Myanmar and Laos). The material developed has wide practical relevance to veterinarians, traditional healers and village or community animal health workers, who all pose a heightened risk of spreading infectious agents.

Genetic Parameters for Growth and Kid Survival of Indigenous Goat under Smallholding System of Burundi.

Simple SummaryGoats play a key multifunctional role in food security and poverty alleviation for small farmers in many less developed countries. Unfortunately, the productivity level of these goats is low. Among the alternatives proposed to overcome this situation, one is to establish a phenotypic breeding program with the support of community breeding organizations. In this study, genetic parameters were estimated for the growth, conformation, and survival of 1538 young goats raised by small farmers in Burundi organized in farmer field schools. Overall, the results suggest that phenotypic selection of growth and conformation traits would be possible if data recording and animal management were improved. On the other hand, efforts to improve survival should focus on improving the environmental conditions in which kids are raised. The role of community breeding organizations and animal health workers is therefore essential to disseminate breeding techniques and methods that optimize animal production and health.The goal of this study was to estimate genetic parameters for the growth, conformation, and survival of goat kids raised in smallholder farming systems in Burundi. To do this, measurements were taken on live weight, thoracic perimeter, length, and height at birth (n = 1538 animals), at 3 months (n = 1270 animals), at 6 months (n = 992 animals), at 9 months (n = 787 animals), and at 12 months (n = 705 animals). Kids were born between 2016 and 2019, from 645 dams and 106 bucks. Three bivariate animal models were used to estimate genetic parameters of body weight and conformation measurements as potential indicators of this weight. According to the measure, heritability was estimated between 15 and 17% and genetic correlations between 65 and 79%. An accelerated failure time animal model was used to estimate the heritability of survival for kids under one year, adjusted for birth weight. Goat survival was significantly prolonged by 0.64 days per kilogram of birth weight. The estimated heritability for this trait was 2%. Overall, these results suggest that a selection program could be implemented to improve animal growth, either directly on weight or indirectly on conformational traits. At the same time, efforts need to be made to improve rearing conditions to increase the survival of kids.

Identification of Peste des Petits Ruminants Transmission Hotspots in the Karamoja Subregion of Uganda for Targeting of Eradication Interventions.

This paper describes an assessment of the patterns of peste des petits ruminants virus circulation in the Karamoja subregion of Uganda conducted to identify the communities that maintain the virus and inform the development of a targeted vaccination strategy. Participatory epidemiological methods were used to develop an operational hypothesis for the patterns of PPR in Karamoja that was subsequently validated through outbreak investigation and genomics. The participatory epidemiological assessment included risk mapping with livestock owners, community animal health workers and veterinarians and indicated there were two critical foci of virus transmission on the Uganda-Kenya border. One was located in two adjacent subcounties of Kotido and Kaabong Districts in northern Karamoja and the other in Loroo subcounty of Amudat District in southern Karamoja. Participants reported that these were locations where outbreaks were usually first observed in Karamoja and subsequently spread to other areas. Following the participatory assessment, surveillance activities were implemented across the Karamoja subregion in 2018. Three outbreak were detected, investigated and sampled. Two outbreaks were located in the northern and one on the southern focus of transmission. No Outbreaks were diagnosed in Karamoja outside of these foci during 2018. Genomics indicated different clusters of viruses were associated with the northern and southern foci that were more closely related to other East African isolates than to each other. This indicates these are two separate systems of virus circulation which should be explicitly addressed in eradication as separate cross-border systems that require integrated cross-border interventions.

Effective promotion of artificial insemination (AI) by private providers in pastoral areas requires stakeholders’ opinion in shaping the direction of their adoption. A structured questionnaire was administered to 384 pastoralists in Kajiado and Narok counties, Kenya to elicit data on willingness to pay for AI services. Double bounded contingent valuation methodology was adapted in computing their willingness to pay for AI services. Results revealed that 90% of farmers were aware of AI of which 51.7 and 50.5% were willing to pay for the services in Kajiado and Narok counties respectively, for an average of Kenya Shillings 1, 853, reflecting a premium of 23.6% placed on AI by pastoralists with reference to the base price of Kenya Shillings (KES) 1,500 offered for exotic breeds in Kenyan highlands. Awareness, herd size and access to extension services significantly increase farmers’ willingness to pay unlike farm income. The study recommends utilization of existing extension networks of community animal health workers to ensure relevant information about AI is disseminated among pastoralists and perform free AI trials on lead pastoralists’ animals to earn others’ confidence. Key words: Artificial insemination, willingness to pay, pastoralists, adoption, contingency valuation, awareness, Maasai.

Participatory evaluation of delivery of animal health care services by community animal health workers in Karamoja region of Uganda.

AimAn evaluation exercise was carried out to assess the performance of Community Animal Health Workers (CAHWs) in the delivery of animal health care services in Karamoja region, identify capacity gaps and recommend remedial measures.Materials & methodsParticipatory methods were used to design data collection tools. Questionnaires were administered to 204 CAHWs, 215 farmers and 7 District Veterinary Officers (DVOs) to collect quantitative data. Seven DVOs and 1 Non Government Organization (NGO) representative were interviewed as key informants and one focus group discussion was conducted with a farmer group in Nakapiripirit to collect qualitative data. Questionnaire data was analyzed using SPSS version 19. Key messages from interviews and the focus group discussion were recorded in a notebook and reported verbatim.Results70% of the farmers revealed that CAHWs are the most readily available animal health care service providers in their respective villages. CAHWs were instrumental in treatment of sick animals, disease surveillance, control of external parasites, animal production, vaccination, reporting, animal identification, and performing minor surgeries. Regarding their overall performance 88.8%(191/215) of the farmers said they were impressed. The main challenges faced by the CAHWs were inadequate facilitation, lack of tools and equipments, unwillingness of government to integrate them into the formal extension system, poor information flow, limited technical capacity to diagnose diseases, unwillingness of farmers to pay for services and sustainability issues.Conclusions and recommendationsCAHWs remain the main source of animal health care services in Karamoja region and their services are largely satisfactory. The technical deficits identified require continuous capacity building programs, close supervision and technical backstopping. For sustainability of animal health care services in the region continuous training and strategic deployment of paraprofessionals that are formally recognised by the traditional civil service to gradually replace CAHWs is recommended.

Community-based tsetse fly control significantly reduces fly density and trypanosomosis prevalence in Metekel Zone, Northwest, Ethiopia.

African animal trypanosomosis is a great obstacle to livestock production where tsetse flies play a major role. Metekel zone is among the tsetse-infested areas. Community-based tsetse fly and trypanosomosis control using targets was conducted from June 2011 to May 2012 in Metekel zone, Ethiopia, to decrease trypanosomosis and tsetse fly. Cloth screen targets were developed, impregnated with 0.1% deltamethrin, and deployed alongside rivers by the research team together with the community animal health workers. Monthly parasitological and entomological data were collected, processed, and compared with similar data collected before control. Overall average tsetse fly (Glossina tachinoides) density decreased from 1.13 to 0.18fly/trap/day after control. The density was decreased in all sites with no significant difference among the sites. However, higher decrements were observed in the dry and late dry seasons by more than 12 and 6 times, respectively. The reduction in overall apparent prevalence of trypanosomosis caused by Trypanosoma congolense, Trypanosoma brucei, and Trypanosoma vivax from 12.14% before to 3.61% after control coincides with the tsetse fly reduction. In all the study sites, significant reduction was observed before and after control. The highest decrement was observed in the late dry season when the apparent prevalence was reduced from 7.89 to 1.17% before and after control, respectively. As this approach is simple, cost-effective, and appropriate for riverine tsetse species, we recommend to be scaled up to other similar places.

Providing animal health services to the poor in Northern Ghana: rethinking the role of community animal health workers?

The Community Animal Health Workers (CAHWs) system has been promoted as an alternative solution to providing animal health services in marginal areas. Yet, access to quality animal health services still remains a fundamental problem for livestock dependent communities. This paper uses the concepts of accessibility, affordability, and transaction costs to examine the perceptions of livestock keepers about the various animal health service providers. The empirical analysis is based on a survey of 120 livestock-keeping households in the Tolon-Kumbungu and Savelugu-Nanton districts in the Northern Region of Ghana. A multinomial logit model was used to determine the factors that influence households' choice of alternative animal health service providers. The results show that the government para-vets are the most preferred type of animal health service providers while CAHWs are the least preferred. Reasons for this observation include high transaction costs and low performance resulting from limited training. In areas with few or no government para-vets, farmers have resorted to self-treatment or to selling sick animals for consumption, which has undesirable health implications. These practices also result in significant financial losses for farmers. This paper finds that the CAHWs' system is insufficient for providing quality animal health services to the rural poor in marginal areas. Therefore, market-smart alternative solutions requiring strong public sector engagement to support livestock farmers in marginal areas and setting minimum training standards for animal health service providers merit policy consideration.

Seroprevalence and sero-conversion after vaccination against Peste des Petits Ruminants in sheep and goats from Awash Fentale District, Afar, Ethiopia

A cross-sectional epidemiological study followed by vaccination and postvaccinal serum antibody assessment against Peste des Petits Ruminants (PPR) in small ruminant population of Awash Fentale District, Afar, Ethiopia, was conducted from September 2006 to June 2007 with the aim of investigating seroprevalence and post-vaccination sero-conversion rate. A total of 1239 sera collected from sheep and goats which were not vaccinated, were screened by using nucleoprotein-based competitive enzyme-linked immunosorbent assay (c-ELISA). Only 21 (1.70%) animals were found to be positive. Following the base-line seroprevalence study, small ruminants in the area were vaccinated using the attenuated homologous PPR virus (Nigeria 75/1) strain vaccine, produced at National Veterinary Institute (NVI) in Debre-Zeit, Ethiopia. A total of 1096 small ruminants were resampled from the vaccinated population fourteen days after vaccination. The postvaccination sero-conversion rate in the population was found to be 61.13%, indicating a relatively weak herd immunity. The main reason for the low sero-conversion could be the thermolabile nature of the vaccine, since no statistically significant difference was observed between small ruminants vaccinated by Veterinary Professionals and Community Animal Health Workers (CAHWs), using Chi-squared test at 95% CI ( P > 0.05). This signifies the need for thermostable vaccine that could potentially increase the herd immunity in addition to that being administered by CAHWs independently. The current finding indicated that CAHWs could participate in vaccination campaigns in such areas as Afar, where there are few veterinarians despite of the huge livestock populations, as means of pastoralists’ livelihood.

Continuing education in the prevention and control of HPAI: a case study on Indonesia

Highly Pathogenic Avian Influenza (HPAI) subtype H5N1 is now endemic in large parts of Indonesia and this situation has revealed, among other constraints, a lack of human resource capacity in many institutions especially in terms of understanding of, and experience in, the control of poultry diseases. Cost-efficient prevention and control of HPAI must be built on a sustainable poultry health programme that incorporates collaborative research and development activities involving the public and private sectors. The programme should provide appropriate education, communication and services to: all poultry producers, workers and traders; community animal health workers; field veterinarians, livestock officers and extension workers; and senior-decision makers at national, provincial and district levels. Lessons learnt in the production of effective education and communication materials that are readily accessible to each target audience are described.

Veterinary paraprofessionals and community animal health workers in Tanzania

To address the economic hardships of the 1980‟s, Tanzania under pressure from its development partners both bilateral and multilateral embarked on structural adjustment program. In the case of veterinary services delivery systems reforms were advocated founded on privatisation and liberalisation. The government abruptly withdrew from providing clinical services, retrenched a substantial number of paraprofessionals and their training sponsorship was withdrawn. The gap created has not been bridged by the private sector which to date is limited to a few major urbanised foci. Rural producers have been the mostly affected by these reforms. The response has been to try and create a new cadre in the delivery of veterinary services and a reduced emphasis on the role of paraprofessionals. The roles of this new cadre commonly referred to as the community based animal health workers (CAHWs) and paraprofessionals are reviewed. We conclude that before any new cadre is introduced in the delivery system, technical and socio-economic sustainability issues should be researched. Furthermore we advocate that the role of paraprofessionals in the private sector and rural areas should be re-examined.

Community‐based Animal Health Care

Livestock contribute to the livelihoods of around 70% of the world's poor. Heifer International provides high quality livestock, training, and related support to communities to assist with food security and to improve livelihoods. Heifer provides training and extension services so families can provide improved animal housing, management, breeding, nutrition, and veterinary health. Heifer conducts training programs for para-vets or Community Animal Health Workers (CAHWs) in areas where local professional veterinary care is not available. Beneficiaries get animal health and husbandry services through trained technicians who are selected from within the community and trained in improved local practices, using basic selection guidelines. The selected community men and women get hands-on training based on the principle of community-based animal health care, using participatory principles in the farmers' fields. Basic tasks of CAHWs in the Heifer-supported project are described. Heifer International is providing sustainable solutions to the well-being of the livestock where it works.

Liens entre agents non professionnels et Services vétérinaires officiels en Afrique au Sud du Sahara

Para-professional agents known as auxiliaries, or community animal health workers, provide low-cost basic veterinary services to communities of livestock producers. A 2003 survey of 16 Sub-Saharan African countries, carried out as part of the Pan-African Programme for the Control of Epizootics, showed that in the majority of cases, the official Veterinary Services have no (or very few) links with the auxiliaries, although they are well aware of their existence and in some cases the auxiliaries have been trained by officials of the Veterinary Services. However, there are isolated cases of countries establishing more formal links, for example, recognising the status of an auxiliary, recognising auxiliaries with no definition of a status, attaching auxiliaries to Veterinary Service staff, establishing agreements for the provision of auxiliary services through livestock producer associations, harmonising auxiliary training programmes, issuing professional auxiliary cards, and setting up a consultation framework on the issue of auxiliaries. Unlike private veterinarians, agents of the official services do not generally perceive auxiliaries as competitors, and sometimes collaboration develops at this level. The authors propose several measures to improve links between the official Veterinary Services and auxiliaries, as follows: the fields of competence of auxiliaries should be defined and their curriculum harmonised, the status of auxiliaries should be recognised, a monitoring and assessment mechanism should be established at senior level in the Veterinary Services, training for livestock producers should be improved.
