Socioeconomic assessment of the relevance of a community-based goat breeding project in smallholding systems.

In the last decade, community-based animal breeding programs have gained attention for the genetic improvement of small ruminants in the tropics. Nevertheless, implementing such programs remains challenged by the issue of smallholders' participation. To shed light on this issue of participation, a goat genetic improvement project has been assessed for its socioeconomic relevance through participatory methods, taking account of goat multifunctionality. We quantified the gross margins per flock and per animal as indicators of viability. We assessed then the correspondence between the goat functions defined through a proportional piling tool with the relative share of these functions in the gross revenue. For that purpose, 160 smallholders were surveyed and 77 among them were monitored for one year. A cluster analysis of factors linked to the dynamic of goat farming identified three groups of farmers. The first group gathered farmers with the smallest goat flocks, who were goat oriented in the future. Their sustainable participation in goat breeding project was impeded by the excessive sales of goats. The second group involved farmers with the highest farm size, who planned to buy cattle to replace part of their goats. The third group included farmers who were members of the project with the largest goat flocks. This group emphasized the importance of goat for their future but showed weak abilities to manage large flocks. The gross margin per animal was the highest in the third group. The relative importance of goat functions as defined through participatory tools did not correspond to the relative share of these functions in the composition of the gross revenue from goats. Participatory tools and economic calculation then appear as complementary to understand farmers' priorities. Consolidating breeders' associations and supporting farmers to diversify their sources of income are two ways proposed here to ensure an enabling environment to goat husbandry and farmers' well-being.

Analysing innovations among cattle smallholders to evaluate the adequacy of breeding programs.

Many breeding programs have been implemented in developing countries, many of which have been unsuccessful. To better understand the failure of these breeding programs, it is proposed to analyze their adequacy with innovations that are actually adopted by smallholders. The proposed methodology takes account of these innovations, the reasons for their adoption and the objectives of livestock keeping. The N'Dama cattle-breeding program in Senegal was used as a case study. Surveys were carried out among 54 farmers: 27 breeders who participated in this program, 17 of whom recently resigned, and 27 breeders who have never participated. Feeding was the most frequently cited area of innovation, followed by infrastructure. Genetics, animal health and reproduction held the third rank. Milk production appeared as an important objective of breeders, although the context remains one of strong multifunctionality. Principal component analysis highlighted three categories of breeders according to the innovations they adopted: institutional, modernizing, and integrating innovators. The groups of institutional and modernizing innovators dominate, gathering each 41% of the farmers. In the first category, breeders have organized themselves in an association and use N'Dama sires, livestock aiming at an insurance objective. In the second category, artificial insemination with exotic breeds and other technical innovations (cowshed, vaccination, urea treatment of straw) are used to improve production of milk and meat. The third group is termed 'integrating innovators,' since their innovations aim at integrating livestock and crop production. Gathering 18% of the sampled breeders, this group presents intermediate features between the two previous groups, using animals as draught power and for manure production. These results indicate that a process of intensification is at play and that the genetic improvement through the selection of N'Dama cattle for production criteria does not meet the breeders' demand. However, the N'Dama's adaptive traits justify its use as part of the breeding strategy of farmers, either in pure-breeding or in crossbreeding. The study thus tends to show the interactive link between genetic improvement and other innovations. It suggests that the success of a breeding program depends on its adequate positioning within the set of innovations adopted by breeders and proposes a method to inform breeding programs accordingly.

The use of antibiotics in cattle in North-East Benin: pharmaceutical inventory and risk practices of cattle breeders.

This study's aim is to inventory antibiotics used in cattle in North-East Benin and assess risk practices that could be the cause of both food chain contamination by antibiotic residues and selection of antibiotic-resistant bacteria in animals and humans. A survey was conducted among 98 cattle breeders in the districts of Banikoara, Kandi, Bembereke, and Kalale in North Benin. Semi-structured interviews were conducted, covering breeder status, breeding system, and antibiotic use. Multiple correspondence analysis and hierarchical classification analysis were conducted to establish a breeder typology. Breeders mainly belonged to the Fulani ethnic group (71.4 ± 8.9%) and almost all of them received "no formal education" (96.9 ± 3.4%). Cattle herds were mainly composed of a single breed, the Borgou (76.4 ± 8.1%) or the Fulani Zebu (16.0 ± 7.0%). Some herds were mixed. Antibiotics groups used in cattle breeding were tetracyclines, beta-lactams, sulfonamides, aminoglycosides, and macrolides, used by respectively 100%, 69.4 ± 9.1%, 56.1 ± 9.8%, 44.9 ± 9.8%, and 34.7 ± 9.4% of breeders. These drugs were purchased in local markets (59.0 ± 15.4%) and veterinary pharmacy (41.0 ± 15.4%). They were mainly used against respiratory diseases, lameness, mastitis, omphalitis and neonatal enteritis, and skin diseases. Only 49.0 ± 9.9% of breeders seek veterinary services to treat animals and 92.9 ± 5.1% of them did not respect antibiotic withdrawal times. These practices suggest that both contamination of bovine meat with antibiotic residues and selection of resistant bacteria are to be expected, resulting in adverse health effects on consumers.

Assessing the diversity of preferences of suburban smallholder sheep keepers for breeding rams in Ouagadougou, Burkina Faso.

Urbanisation in developing countries entails deep changes in the livestock sector and the management of animal genetic resources (AnGR). Sheep breeding around Ouagadougou (Burkina Faso) illustrates these changes and the need to coordinate genetic improvement in general and the use of crossbreeding in particular. For this, it is important to understand breeders' choices and improvement strategy, to accompany them within a national plan for AnGR management. In a context of missing market for breeding rams, a stated choice experiment was conducted with 137 farmers, together with a characterisation of herd management practices. This survey analyses farmers' preferences for breeding rams, estimating their willingness to pay (WTP) for different traits (attributes). Their practices were characterised by a high reliance on natural pastures (82% of farmers) and a minority of crossbreeding (23%). The highest WTP was observed for disease resistance. However, the subgroup of farmers practicing crossbreeding showed a tolerance to high susceptibility. A strong preference for the white colour was revealed. Although significant, the influence of sheep body size on decision-making showed a lesser importance, again with a distinct behaviour in the subgroup practicing crossbreeding. These results illustrate the need to take account of the diversity of goals and preferences among smallholder sheep keepers to gain their adhesion to a coordinated genetic improvement framework.

Market organization and animal genetic resource management: a revealed preference analysis of sheep pricing.

Farm animal genetic resources are threatened worldwide. Participation in markets, while representing a crucial way out of poverty for many smallholders, affects genetic management choices with associated sustainability concerns. This paper proposes a contextualized study of the interactions between markets and animal genetic resources management, in the case of sheep markets in Ouagadougou, Burkina Faso. It focusses on the organization of marketing chains and the valuation of genetic characteristics by value chain actors. Marketing chain characterization was tackled through semi-structured interviews with 25 exporters and 15 butchers, both specialized in sheep. Moreover, revealed preference methods were applied to analyse the impact of animals' attributes on market pricing. Data were collected from 338 transactions during three different periods: Eid al-Adha, Christmas and New Year period, and a neutral period. The neutral period is understood as a period not close to any event likely to influence the demand for sheep. The results show that physical characteristics such as live weight, height at withers and coat colour have a strong influence on the animals' prices. Live weight has also had an increasing marginal impact on price. The different markets (local butcher, feasts, export market, sacrifices) represent distinct demands for genetic characteristics, entailing interesting consequences for animal genetic resource management. Any breeding programme should therefore take this diversity into account to allow this sector to contribute better to a sustainable development of the country.

Cultural Practices Shaping Zoonotic Diseases Surveillance: The Case of Highly Pathogenic Avian Influenza and Thailand Native Chicken Farmers.

Effectiveness of current passive zoonotic disease surveillance systems is limited by the under-reporting of disease outbreaks in the domestic animal population. Evaluating the acceptability of passive surveillance and its economic, social and cultural determinants appears a critical step for improving it. A participatory rural appraisal was implemented in a rural subdistrict of Thailand. Focus group interviews were used to identify sanitary risks perceived by native chicken farmers and describe the structure of their value chain. Qualitative individual interviews with a large diversity of actors enabled to identify perceived costs and benefits associated with the reporting of HPAI suspicions to sanitary authorities. Besides, flows of information on HPAI suspected cases were assessed using network analysis, based on data collected through individual questionnaires. Results show that the presence of cockfighting activities in the area negatively affected the willingness of all chicken farmers and other actors to report suspected HPAI cases. The high financial and affective value of fighting cocks contradicted the HPAI control policy based on mass culling. However, the importance of product quality in the native chicken meat value chain and the free veterinary services and products delivered by veterinary officers had a positive impact on suspected case reporting. Besides, cockfighting practitioners had a significantly higher centrality than other actors in the information network and they facilitated the spatial diffusion of information. Social ties built in cockfighting activities and the shared purpose of protecting valuable cocks were at the basis of the diffusion of information and the informal collective management of diseases. Building bridges with this informal network would greatly improve the effectiveness of passive surveillance.

Financial Impacts of Priority Swine Diseases to Pig Farmers in Red River and Mekong River Delta, Vietnam.

A study was conducted between May 2013 and August 2014 in three provinces of Vietnam to investigate financial impacts of swine diseases in pig holdings in 2010-2013. The aim of the study was to quantify the costs of swine diseases at producer level in order to understand swine disease priority for monitoring at local level. Financial impacts of porcine reproductive and respiratory syndrome (PRRS), foot and mouth disease (FMD), and epidemic diarrhoea were assessed for 162 pig holders in two Red River Delta provinces and in one Mekong River Delta province, using data on pig production and swine disease outbreaks at farms. Losses incurred by swine diseases were estimated, including direct losses due to mortality (100% market value of pig before disease onset) and morbidity (abortion, delay of finishing stage), and indirect losses due to control costs (treatment, improving biosecurity and emergency vaccination) and revenue foregone (lower price in case of emergency selling). Financial impacts of swine diseases were expressed as percentage of gross margin of pig holding. The gross margin varied between pig farming groups (P < 0.0001) in the following order: large farm (USD 18 846), fattening farm (USD 7014) and smallholder (USD 2350). The losses per pig holding due to PRRS were the highest: 41% of gross margin for large farm, 38% for fattening farm and 63% for smallholder. Cost incurred by FMD was lower with 19%, 25% and 32% of gross margin of pig holding in large farm, fattening farm and smallholder, respectively. The cost of epidemic diarrhoea was the lowest compared to losses due to PRRS and FMD and accounted for around 10% of gross margin of pig holding in the three pig farming groups. These estimates provided critical elements on swine disease priorities to better inform surveillance and control at both national and local level.

The Perceived Value of Passive Animal Health Surveillance: The Case of Highly Pathogenic Avian Influenza in Vietnam.

Economic evaluations are critical for the assessment of the efficiency and sustainability of animal health surveillance systems and the improvement of their efficiency. Methods identifying and quantifying costs and benefits incurred by public and private actors of passive surveillance systems (i.e. actors of veterinary authorities and private actors who may report clinical signs) are needed. This study presents the evaluation of perceived costs and benefits of highly pathogenic avian influenza (HPAI) passive surveillance in Vietnam. Surveys based on participatory epidemiology methods were conducted in three provinces in Vietnam to collect data on costs and benefits resulting from the reporting of HPAI suspicions to veterinary authorities. A quantitative tool based on stated preference methods and participatory techniques was developed and applied to assess the non-monetary costs and benefits. The study showed that poultry farmers are facing several options regarding the management of HPAI suspicions, besides reporting the following: treatment, sale or destruction of animals. The option of reporting was associated with uncertain outcome and transaction costs. Besides, actors anticipated the release of health information to cause a drop of markets prices. This cost was relevant at all levels, including farmers, veterinary authorities and private actors of the upstream sector (feed, chicks and medicine supply). One benefit associated with passive surveillance was the intervention of public services to clean farms and the environment to limit the disease spread. Private actors of the poultry sector valued information on HPAI suspicions (perceived as a non-monetary benefit) which was mainly obtained from other private actors and media.

When private actors matter: Information-sharing network and surveillance of Highly Pathogenic Avian Influenza in Vietnam.

The effectiveness of animal health surveillance systems depends on their capacity to gather sanitary information from the animal production sector. In order to assess this capacity we analyzed the flow of sanitary information regarding Highly Pathogenic Avian Influenza (HPAI) suspicions in poultry in Vietnam. Participatory methods were applied to assess the type of actors and likelihood of information sharing between actors in case of HPAI suspicion in poultry. While the reporting of HPAI suspicions is mandatory, private actors had more access to information than public actors. Actors of the upstream sector (medicine and feed sellers) played a key role in the diffusion of information. The central role of these actors and the influence of the information flow on the adoption by poultry production stakeholders of behaviors limiting (e.g. prevention measures) or promoting disease transmission (e.g. increased animal movements) should be accounted for in the design of surveillance and control programs.

A Systematic Scoping Study of the Socio-Economic Impact of Rift Valley Fever: Research Gaps and Needs.

Rift Valley fever (RVF) is a severe mosquito-borne disease affecting humans and domestic ruminants. RVF virus has been reported in most African countries, as well as in the Arabic Peninsula. This paper reviews the different types of socio-economic impact induced by RVF disease and the attempts to evaluate them. Of the 52 papers selected for this review, 13 types of socio-economic impact were identified according to the sector impacted, the level and temporal scale of the impact. RVF has a dramatic impact on producers and livestock industries, affecting public and animal health, food security and the livelihood of the pastoralist communities. RVF also has an impact on international trade and other agro-industries. The risk of introducing RVF into disease-free countries via the importation of an infected animal or mosquito is real, and the consequent restriction of access to export markets may induce dramatic economic consequences for national and local economies. Despite the important threat of RVF, few studies have been conducted to assess the socio-economic impact of the disease. The 17 studies identified for quantitative analysis in this review relied only on partial cost analysis, with limited reference to mid- and long-term impact, public health or risk mitigation measures. However, the estimated impacts were high (ranging from $5 to $470 million USD losses). To reduce the impact of RVF, early detection and rapid response should be implemented. Comprehensive disease impact studies are required to provide decision-makers with science-based information on the best intervention measure to implement ensuring efficient resource allocation. Through the analysis of RVF socio-economic impact, this scoping study proposes insights into the mechanisms underpinning its often-underestimated importance. This study highlights the need for comparative socio-economic studies to help decision-makers with their choices related to RVF disease management.

Tuareg ethnoveterinary treatments of camel diseases in Agadez area (Niger).

For generations, nomadic herders have been learning to manage herd health, particularly in dromedaries because of their great value. Owing to the unavailability of veterinary services, camel herders in remote areas have been developing their own pharmacopoeia and veterinary techniques. The bleeding of sick animals is a common treatment, as Tuareg herders believe that 'tainted blood' (izni) is the cause of many conditions. Several surgical techniques are also used, such as excision of calcified sublingual cord. The remedies mentioned in this survey are derived from Maerua crassifolia, Boscia senegalensis, Acacia raddiana, Cucumis prophetarum, Calotropis procera, Ricinus communis, Citrullus colocynthis, green tea, millet, tobacco and onions. Artificial elements are also used for treatment of animals: Powders collected from batteries, various haircare or skincare creams, crushed glass, insecticides or motor oil belong to their pharmacopoeia. This broadmindedness allows the introduction of modern veterinary medicine. Factors such as the lack of real production objectives constitute limits to this progress, however.
