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...

Associations among chemical properties, in vitro digestibility and ruminal degradability characteristics of herbaceous legumes, browse species and oilseed cakes were studied using correlation analysis based on a total of 50 feedstuff samples. Chemical properties were poorly related to in vitro or...

Milk yield, milk composition and body weight change of crossbred dairy cows (Holstein Friesian X Zebu) were studied in the urban and peri-urban dairy production systems in the Addis Ababa milk shed between December 1997 and November 1998. Ninety-seven cows, with parities above two and at the begi...

The effect of dietary protein supplementation on the resistance of lambs to endoparasites was examined in Horro and Menz lambs artificially infected with Haemonchus contortus. The experimental design involved 2 breeds, 2 infection treatments (infected Vs non-infected) and 3 nutrition treatments. ...
