“…The very high proportion of milk consumed, 73-78%, would be related to the ethnic group present, the Fulani, whose dietary habits are based on the consumption of milk and derived products. Diop et al (2009) also reported a signi cant proportion of milk consumed by the Fulani (35.4%), which is lower than our results. We agree with these authors that the amount of milk used is a function of the ethnic group, marketing opportunities and the amount of milk available from the herd.…”

The insu ciency and variability of pasture production is a determining factor in milk production, particularly in the Sahelian zone. The objective of this study was to characterize dairy production systems and their relationship with crops to meet livestock needs. It consisted of surveys of 120 farmers in four communes in the Séno province. The results show three groups of dairy farmers that are essentially differentiated by the main activity and the sex of the farmers as well as the size of the cattle herd on the farm. The rst group is made of male agropastoralists, with herds averaging 12 cattle. Group 2 consists of male agropastoralists with an average of 22 cattle. Group 3 consists of female pastoralists (96.15%), with a herd size of about 19 head. The cows are fed on pasture and supplemented with crop residues with cotton cake, which is more important in group 2, where more farmers have hayloft for fodder conservation and manure pits compared to the other two groups. Crop residues are used primarily as feed in all groups from January to May. This supplementation allows the maintenance of milk production in the dry season and group 2, with more dairy cows, records more milk milked (6.5 and 3.8 l) and consumed in wet and dry seasons compared to the other two groups. The results suggest that the farmers in the area have low technical level and need capacity building in agropastoral elds to improve their production.

“…L'évolution de la production de lait des Girolando s'explique par la maitrise des techniques d'élevages de cette race nouvellement introduite au Bénin en provenance du Brésil et par leur adaptation progressive dans leur nouveau biotope. Dans les campements peulhs de la zone sylvopastorale du Sénégal, les vaches Zébu Gobra ont donné en moyenne 0,87 litre de lait en 1997 et une valeur moyenne de 1 litre de lait par jour en 2000 (Diop et al, 2009). En milieu rural au Niger, le zébu Azawak a produit en moyenne 1,7 kg de lait par jour en 2000 et 1,82 kg de lait en 2001 (Oumarou, 2004).…”

RÉSUMÉLe faible niveau de production de lait du bétail et la non maîtrise des facteurs qui agissent généralement sur cette production, sont les principaux goulots d'étranglement pour la sécurité alimentaire dans le domaine du lait et des produits laitiers en Afrique de l'Ouest. Ces facteurs sont d'ordres génétique et non génétique et méritent d'être élucidés dans le cadre de l'amélioration de la production du lait des vaches. Cet article passe en revue les effets des principaux facteurs non génétiques (stade de lactation, rang de mise bas, saison de mise bas, alimentation, etc.) et génétiques (race, sélection, croisement, etc.) sur la production de lait des races bovines en Afrique de l'Ouest. La contribution de la biotechnologie animale à la diffusion du progrès génétique a été également abordée. Cette synthèse ressort au préalable l'origine, l'aire de distribution géographique et les performances des principales races bovines exploitées pour la production de lait en Afrique de l'Ouest. © 2016 International Formulae Group.

Performances of milk production of West Africa cattle breeds ABSTRACTThe low level of livestock milk production and the uncontrol of factors that generally affect the production are the main handicaps of food security in the milk products field in West Africa. These factors are genetic and non-genetic orders and should be understood in the context of cows' milk production improvement. This scientific paper examines the effects of the main non-genetic factors (stage of lactation, rank calving, calving season, feeding etc) and genetic (breed, selection, crossing, etc). The animal biotechnology contribution for genetic progress spreading has been tackled. This synthesis first spring origin, geographic range and performance of the main breeds used for milk production in West Africa.

“…It can affect the woody vegetation by damaging adult trees or regeneration. Livestock has significantly increased since the beginning of the 20th century [69], though the censuses are rare and difficult in this pastoral area. Miehe et al [28] estimated the cattle to 9000 heads and sheep and goats to 18,000 heads within an area of 15 km around Widou Thiengoly.…”

The persistence of the woody vegetation of the Sahelian savannas, and their supported ecosystem functions, have been questioned since the great drought of 1970s–1980s. To assess the resilience of this vegetation to drought and grazing, we undertook a trait-based approach using field inventory, historical survey databases, and traits data literature. Using a hierarchical clustering approach, we gathered the species present from 1970 to 2015 into functional groups according to their effect traits related to primary productivity and biogeochemical cycles. First, we studied the evolution of functional redundancy (FRe) and response diversity (RDiv) of the functional effect groups to drought and grazing, two indicators of resilience, since the 1970s. Second, we looked at the spatial variation of these two indices in 2015, according to local topography. FRe and RDiv of 80% of the functional groups examined declined since 1970, endangering the persistence of the studied functions. Local topography strongly influenced current FRe and RDiv, with depressions presenting higher values. Finally, by examining species’ abundances, their regeneration, and the functional group to which they belong, we determined some key species that could benefit from protection to ensure the persistence of the ecosystem functions supported by the woody vegetation. This study has expanded knowledge about the savanna’s response to pressures and has shown how a functional traits-based approach could be an effective tool to guide the management of tropical savannas.
