This study characterises farmer’s preferences for breeding rams and tackles their willingness to contribute to the wool sheep Koundoum conservation programme through their quantified appreciation of the main phenotypic features of the sheep breed in the region. In Tillabéri region, i.e. the Koundoum sheep’s area of origin, the proportional piling tool is first used in 11 focus group discussions of breeders to determine the main selection criteria of breeding rams. The multi-attribute analysis me

The carcass weight and the breast meat production of broiler chickens could be effectively stimulated by dietary factors, such as by reducing dietary crude protein content with essential amino acid supplementation and by applying butyrate as a feed additive. These nutritional strategies seem to be the proper tools to increase carcass yield and to improve meat quality of broilers, contributing to more efficient and healthy poultry meat production.

The research was carried out on cows fed with a conventional or green fodder diet in order to determine the physicochemical characteristics and mineral content in milk. The data show similar results except for the fat content, which is higher in milk coming from cows fed with hydroponic barley. Minerals were in the range reported elsewhere. The hydroponic fodder system seems to be an ideal solution in places where it is not possible to grow fresh fodder or where pasture grazing is nonexistent.

Sheep milk production and ingredients are influenced by genetic and environmental factors. In this study, we implemented selection signature analysis to identify candidate genes related to ovine milk traits. The results revealed six selection signature regions showing signs of being selected (P < 0.001) located in chromosomes 1, 2, 3, 6, 13 and 18. In addition, 38 QTLs related to sheep milk performance were identified in selection signature regions, which contain 334 candidate genes.
