Livestock keeping is critical for many of the poor in the developing world, often contributing to multiple livelihood objectives and offering pathways out of poverty. Livestock keeping also affects an indispensable asset of the poor, their human capital, through its impact on their own nutrition and health. This paper outlines the linkages between livestock keeping and the physical well-being of the poor, and examines a number of commonly held beliefs that misrepresent livestock development issues related to these linkages. These beliefs limit the scope of intervention programs to promote livestock and limit their potential contribution to poverty reduction. Recognition of the complexity of the role livestock play in household decision-making and of the opportunities foregone due to these misconceptions can enhance the ability of livestock to contribute to human well-being in the developing world.

Increasingly, value chain approaches are integrated with multi-stakeholder processes to facilitate inclusive innovation and value chain upgrading of smallholders. This pathway to smallholder integration into agri-food markets has received limited analysis. This article analyses this integration through a case study of an ongoing smallholder dairy development programme in Tanzania. Value chain upgrading and innovation systems perspectives were combined in an analytical framework to interpret the findings, which show that multi-stakeholder processes enhance horizontal and vertical coordination but limit process and product upgrading. The main conclusion is that, although such processes may catalyze smallholder market inclusion, their effects are largely bounded by existing value chain structures (e.g. production system, fragmented markets), timeframe and how prevailing institutional constraints are addressed, which may constrain the intentions of such collaboration action. This calls attention to the starting points of value chain interventions and the socio-political dynamics that are part of multi-stakeholder processes.De plus en plus, on intègre l'approche de la chaîne de valeur à celle de l'étude des processus de diverses parties prenantes, afin de faciliter l'innovation inclusive et l'amélioration de la chaîne de valeur des petits cultivateurs. Le trajet d'intégration des petits agriculteurs aux marchés agroalimentaires n'a pas été très analysé. Cet article examine cette intégration à travers une étude de cas, celui d'une petite exploitation agricole et laitière, faisant partie d'un programme de développement en Tanzanie. Au sein d'un cadre analytique d'interprétation des résultats, on a intégré les perspectives d'amélioration de la chaîne de valeur et des systèmes d'innovation. On a vu que les processus impliquant divers parties prenantes renforcent la coordination horizontale et verticale, mais au même temps ils limitent la valorisation des produits et des procès. La conclusion principale est que même si ces processus servent de catalyseurs a l'intégration des petits cultivateurs au marché, leurs effets sont délimites par la structure existante de la chaîne de valeur (par exemple, le système de production, la fragmentation des marchés), par la période considéré, et par comment les contraintes institutionnelles sont abordés, puisqu'elles peuvent limiter les intentions de ces actions collaboratives. D'ici on veut porter l'attention sur le point de départ des interventions sur les chaînes de valeur, et aussi sur les dynamiques sociopolitiques qui font partie des processus avec diverses parties prenantes.

BackgroundHelminth infections in small ruminants are serious problems in the developing world, particularly where nutrition and sanitation are poor. This study investigated the burden and risk factors of gastrointestinal nematode parasite infections in sheep and goats kept in smallholder mixed farms in the Kenyan Central Highlands. Three hundred and seven small ruminants were sampled from 66 smallholder mixed farms in agro-ecological zones 1 (humid) and 3 (semi-humid) in the Kenyan Central highlands. The farms were visited once a month for eight months during which a health and production survey questionnaire was administered. Fecal samples were collected at each visit from each animal. Fecal egg counts (FEC) were performed using the modified McMaster technique. Associations between potential risk factors and FEC were assessed using 3-level Poisson models fit in SAS using GLIMMIX macro. Correlations among repeated observations were adjusted for using three different correlation structures.ResultsA rise in FEC was observed two months after the onset of rains. Farmer education, age category, de-worming during the preceding month and grazing system were significant predictors of FEC. Additionally, there were significant interactions between grazing system and both de-worming and age category implying that the effect of grazing system is dependent on both de-worming status and age category; and that the effect of de-worming depends on the grazing system. The most important predictors of FEC in the study area were grazing system, de-worming status and education of the farmers.ConclusionSince several factors were important predictors of FEC, controlling gastrointestinal helminths of small ruminants in these resource-poor smallholder mixed farms requires a sustainable integrated helminth control strategy that includes adoption of zero-grazing and more farmer education probably through extension services. Achieving improved helminth controls in these resource-poor farming systems offers an opportunity to increase small ruminant productivity and hence has a potential of improving the livelihood of the resource-poor farmers.

Concerns about food safety are increasing in developing countries where urbanization and changing life styles are associated with greater dependence on marketed foods. Ensuring the safety of animal products supplied from smallholder and pastoral systems in these countries presents a great challenge. The risk of consumer exposure to marketed milk containing antimicrobial residues was investigated by testing 986 samples of unpasteurized milk collected in dry and wet seasons from market agents along milk supply chains in and around Mwanza and Dar es Salaam in Tanzania during 1999 and 2000 and estimating the frequency of consuming such milk. With the Charm-AIM screening test kit, antimicrobial residues were detected in 36% of marketed milk samples, suggesting an average risk of about 11 exposures per month for a daily consumer of milk. The higher prevalence levels of the residues were not significantly different by site or season, as had been hypothesized. Recommendations to address this problem are (i) creation of awareness among policy makers, who are currently unaware of the milk safety problem, and development of potential interventions to address the problem, (ii) testing for the residues at milk collection centers, and (iii) further investigation of milk production practices used by the predominantly smallholder producers and market agents. Risks should be characterized and estimated to provide a basis for designing appropriate extension messages and effective management strategies for protecting the health of consumers without unnecessarily jeopardizing the livelihood benefits derived from dairying by producers and market agents.
