The study was conducted to evaluate the reproduction efficiency of zebu and crossbred cows measured by the inter-estrus and inter-service intervals using data from Bako Agricultural Research Center. The overall mean inter-estrus and inter-service intervals were 44.3 t 0.85 and 49.1 t 1.24 days, r...

The zebu cattle "breeds" of eastern and southern Africa are broadly classified into "large" and "small" types. Boran, Karamajong and Sudanese Zebu are examples of the former, while those of the latter include Angoni, Nkedi and Nandi. The habitat of the large zebu is drier than that of the small t...

Many efforts to increase milk and meat production by importing temperate breeds into the tropics are constrained by the breeds' lack of adaptation to tropical diseases, biologic and present management stresses. Moreover, feeding regimes developed for temperate breeds also do not suit animals indi...

The milk and meat productivity of Ethiopia's 27 million cattle is still low for the human population of 53 million, which grows at 2.9 percent yr and is expected to surpass 65 million at the end of this century. The present cattle population includes 40 percent (10.8 million) cows of breeding age...
