Synergies between veterinarians and para-professionals in the public and private sectors: organisational and institutional relationships that facilitate the process of privatising animal health services in developing countries

The delivery of veterinary services in most developing countries was, until recently, considered to be the responsibility of the public sector. However, over the past four decades, economic constraints and the imposition of structural adjustment policies (SAPs) have led to a gradual decline in public sector investment in real terms and thus a reduction in the quality and quantity of services available to livestock keepers. Many governments acknowledged that they were no longer able to provide services that were essentially of a 'private good' nature and introduced radical policy changes which sought to introduce the concepts of a market orientated approach towards agriculture and livestock production in particular. The role of government, in the future, would be to provide a reduced range of essential 'public good' services and to create a favourable environment in which the private sector could become established as a provider of 'private good' services and at the same time act as a partner in carrying out certain public functions under contract or 'sanitary mandates'. In almost all developing countries, however, these policy changes were not accompanied by appropriate development strategies. The reasons for this are complex. Firstly, SAPs may be considered to have been foisted upon governments by donors and are thus perceived by many policy-makers as the cause of financial problems, rather than a solution to them. Secondly, most animal health senior policy-makers in the public sector have been trained as veterinarians and lack the required management skills to plan change effectively. Furthermore, as regards clinical veterinary service delivery, especially in rural or more remote areas, the solution fostered by donor investment, which involves deregulation and the deployment of privately operating para-professionals, is often perceived as a threat to the veterinary profession and might result in limiting access to international markets for the trade of livestock and livestock products. An informal delivery system has gained a foothold in many developing countries in the absence of a well-planned strategy for the privatisation of animal health services. Most governments would now acknowledge that this presents a greater risk than the deployment of well-regulated and effectively supervised para-professionals. This paper explores some of the principal challenges facing policy-makers in their efforts to bridge the transition from full state provision of animal health services to the formation of a partnership with the private sector. Governments and donors need to take active steps to facilitate the process of privatisation of animal health services, especially those targeting the poorer rural subsistence and pastoralist farming systems. This would entail an initial investment in developing the necessary management skills at all levels in the delivery system. Thereafter, further investment would be required to allow the changes to be managed using tools such as the strategic planning cycle. Should sufficient resources be made available to allow the full participation of all stakeholders in the delivery of animal health services, appropriate institutions and effective organisational relationships addressing all the more important issues will have to be identified. The paper then proceeds to describe how different livestock production systems determine the level of demand for animal health services. If these services are to be provided on a financially sustainable basis, they must be tailored to meet actual rather than perceived demand. Identifying an appropriate model for animal health service delivery thus requires careful analysis of the production system to be targeted. Governments and donors can play a useful role in providing resources for this type of study as well as for appropriate market studies, business planning, training and access to soft loans. Finally, as regards regulation, as the law stands today, many activities currently practised by para-professionals are classified as 'acts of veterinary medicine or surgery' and may only legally be performed by qualified and registered veterinarians. The concept of 'principal' and 'subsidiary' legislation provides the necessary flexibility in the regulation of the delivery of animal health services to accommodate the rapid changes taking place in this environment today. Deregulation involves the delegation of responsibility for the performance of a defined range of veterinary interventions to para-professionals under the 'supervision' or 'direction' of a registered veterinarian. The author illustrates how the experiences of a number of projects in Tanzania were used to propose a definition of 'supervision' in law. The definition offers an opportunity to overcome the fear of compromising standards of delivery of animal health services through the deployment of para-professionals. In addition, such functioning provides employment opportunities for private veterinarians in rural areas where access to formal primary animal health services would otherwise be denied and may contribute to the process of quality assurance of national veterinary services in developing countries.

Foot and mouth disease in Zambia: a review of the aetiology and epidemiology and recommendations for possible control

In Zambia, foot and mouth disease (FMD) has been caused by all three of the South African Territories serotypes (SAT 1, 2 and 3) and by European types O and A. Three areas of the country which have experienced repeated occurrences of the disease are considered high-risk areas. The three areas are as follows: the southern border area between Zambia and Zimbabwe, Botswana and Namibia, the Kafue Flats and the northern border with Tanzania in the Nakonde and Mbala districts. The transfer mechanism of the virus is poorly understood but the African buffalo (Syncerus caffer) is considered to be the natural host, acting as a reservoir of infection for the SAT types of the virus. Cattle are known to be carriers of the virus for up to two and a half years and individual semi-domesticated buffalo have been reported to act as carriers for up to five years. In wild herds of buffalo, the virus has been recorded for periods of up to twenty-five years. Current control measures include mass vaccination of cattle in high-risk areas and restrictions on the movement of cattle from areas in which contact exists with buffalo. New protocols should be developed for the prevention and control of FMD, including the enforcement of livestock movement control, improved disease surveillance and reporting, and the monitoring of FMD virus in carrier cattle and buffalo. These measures will contribute towards building the confidence of the regulatory bodies of importing countries in the region.

Seroepidemiological studies of bovine babesiosis on Pemba Island, Tanzania

Serological evidence of infection with Babesia bovis and Babesia bigemina at a number of sites in Pemba was obtained using an enzyme-linked immunosorbent assay (ELISA) capable of detecting the appropriate parasite-specific antibody. Overall, 96% of animals were found to be positive for B. bovis, 88% were positive for B. bigemina and 88% were positive for both Babesia species. Antibody to B. bovis and B. bigemina was detected early in life in a number of calves born on Pemba, and was considered to be of maternal origin. The amount of maternal antibody in the serum of individual animals fell throughout the first 3 months of life. Later in life, antibody levels increased, probably in response to Babesia infection from natural tick challenge. These results suggest that infection with both Babesia parasites is widespread throughout Pemba and that both parasites probably exist in an enzootically stable situation.

Identification of Babesia bovis and Cowdria ruminantium on the island of Unguja, Zanzibar

Babesia bovis and Cowdria ruminantium were identified for the first time in cattle on Unguja Island, Zanzibar. B bovis is common and widespread, although clinical disease had not been diagnosed previously. The vector of heartwater, Amblyomma variegatum, is found throughout Unguja but C ruminantium appears to be more localised in distribution than B bovis.
