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...

The paper gives an example of the use of survival analysis to examine time to conception for a breed by nutrition factorial experiment and the relationship between time to conception and body weight. The example is made complicated by confounding between the treatments and the weight of animals a...

Although the importance of bull reproduction in enhancing genetic progress and influencing cow herd fertility has long been recognized in many parts of the world, there has been very little attention paid to bulls in Ethiopia. Proper management of young bulls aims to improve growth rate so that t...

Based on the promising results obtained from on-station, the cow traction study was further taken to on-farm for verification under the Ethiopian smallholder farmers management conditions. The study was undertaken in Holetta area between 1992 and 1996 by involving 14 farmers. Mean dairy milk yiel...
