Effects of management alternatives on stover quality and productivity]Determinants of ruminant nutritional quality of pearl millet [Pennisetum glaucum (L.) R.Br.] stover: I. Effects of management alternatives on stover quality and productivity

he small amount of on-farm research that has been carried out with fodder trees in Africa has mainly involved exotic species selected by researchers rather than farmers. In this study, farmers who had participated in a pre-planting survey chose, during feedback meetings, seedlings of indigenous, ...

Contrasting herbage diets were fed to lambs to evaluate their effect on subsequent development of Trichostrongylus colubriformis larvae in faeces and on pasture. The diets had either no condensed tannin (CT), lucerne (Medicago sativa cv. Otaio), white clover (Trifolium repens cv. Tahora), or had ...

The study was conducted to determine the economical performance of cross chicken (RIR x FAY). For this purpose four different recipes/ration R1 , R2 , R3 and R4 were offered to the chicken. The laying and hatching performance of these birds were observed for two months of the conduct of experimen...

Post-weaning growth performance was studied for 342 steers out of Africander cows and by Africander, Brahman. Charolais, Hereford and Simmental sires. In a system of intensive fattening, the latter three Bos taurus sire-breed progeny-groups performed strikingly better than the former two Bos indi...

Objectives: To identify management and operational functions, recommended by feed-company personnel and swine producers, that have the potential to decrease the risk of pathogens being transmitted among swine farms through movement of feed trucks. Materials and methods: Focus groups and key-info...

Production performance of indigenous beef breeds of southern Africa were investigated. Discussions and data on calving rate, calf mortality, weaning and birth weights, adult live weights, carcass yield, and feed conversion efficiency; in comparison to crossbreds of Friesian and Hereford cattle in...

Mycotoxins affect poultry production by being present in the feed and directly causing a negative impact on bird performance. Carry-over rates of mycotoxins in animal products are, in general, small (except for aflatoxins in milk and eggs) therefore representing a small source of mycotoxins for h...
