Approximately 320 East African Zebu cows over 36 months of age were monitored monthly from 1986 to 1992 in nine village herds in an area of high trypanosomiasis risk in southwest Ethiopia where there was resistance to all available trypanocidal drugs. Cows were individually treated with diminazen...

Data on reproductive performance of Zebu and Friesian X Zebu crossbred cows reared under small-scale dairy farms were analysed and the effects of genotype, parity, body condition score (BCS), season, and year of calving were examined for a total of 246 calvings. Uterine involution was completed e...

Plasma progesterone profiles were used to monitor post-partum reproductive activity in 12 Small East African Zebu (Bos indicus) cows allocated to either supplementary or no supplementary feeding (control) with continious or restricted (twice daily) suckling regimes. Intact bulls were used for bre...

The effect of boar genotype on the reproductive performance of local sows was investigated. Large White (LW) and local Mukota boars were mated to 20 sows over 3 parities and the performance of the sows and litters were compared up to weaning. Data on the gestation length, number of piglets born a...

This overview aims at browsing the scene of action for research on the resistance of small ruminant to endoparasites in sub-Saharan Africa. After recalling the main sheep and goat breeds, it describes the geographic distribution of these populations in the continent, mentions the farming systems ...

This study arose from the need to develop strategies that optimize the use of available feed resources from natural range fallow and crop residues in combination with the fodder bank innovation. The paper discusses the interactive effects of feeding both forage legume and urea molasses supplement...
