Slaughter data from 304 Menz and 153 Horro rams were analysed to determine between breeds differences in yields of carcass and edible non-carcass components, with the primary aim of creating awareness in the way animal evaluations for meat production may be modified to incorporate local cultures....

Slaughter data from 304 Menz and 153 Horro ram lambs were analyzed to determine between breed differences in yields of carcass and edible non-carcass components. Average age at slaughter was 515 days. Total edible non-carcass component yield (ENCC) was obtained as the sum of weights of blood, lun...

With some 180 million head. comprising more than 150 different breeds or populations of taurine Bos taurus, indicine B. indicus and intermediate origin, the African continent is home to an enormous reservoir of cattle biodiversity. Recent archaeological findings are providing new insights into th...

Data on 969 lambs collected over a 10-year period (1978 to 1987) on Dorper sheep at Ol'Magogo were used in this study. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages of growth. Heritability estimates from paternal half-sib analysis were: ...

A selection programme (PNSO) was set up in 1983 in Cote d'Ivoire to increase growth and liveweight of the indigenous Djallonke sheep, using open nucleus breeding system. Selection was based on male individual weight at 80, 180 and 365 days of age. 10,417 records on 80 day weights (WT80) of lambs ...

The Menz and Horro highland sheep breeds are being evaluated at the ILCA Debre Birhan research station in Ethiopia for between-and within-breed genetic variation for resistance to internal parasites. The experimental design involves mating, for each breed, 150 ewes with 10 rams to lamb at the beg...
