Retrospective studies were conducted in Kafta-Humera and Wukro areas of Tigray region of Ethiopia. A retrospective study was carried out on 12 herds consisting 2144 Begait cattle from pastoral and agro-pastoral areas to assess herd composition and calf-crop. To evaluate the reproductive performan...

Breed additive and non-additive effects, and genetic parameters of milk fat, protein, solids not fat (SNF) and total solids (TS) percents, were estimated in Ethiopian Boran cattle and their crosses with Friesian in central Ethiopia. Ethiopian Boran cattle were consistently superior (P<0.01) to th...

This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...

Five tropically adapted buck breeds extensively managed in Ethiopia were studied to determine possible effects of breed and age on body size and testicular traits. In all, 177 bucks were selected following stratified random sampling, and evaluated in three age groups: <14 months (young), 14-19.5 ...
