The world's domestic animal breeds represent an important resource for economic development and livelihood security. Extensive genetic diversity in these breeds allows the existence of livestock in all but the most extreme environments globally, providing a range of products and functions. Unfort...

We used a partial-budget analysis to evaluate profitability of different management strategies of three genotypes of sheep in a 2 × 2 × 3 factorial experiment conducted at Debre Berhan research station in the central highlands of Ethiopia. This involved two anthelmintic-treatment levels (treated ...

Hybridization between yak Poephagus grunniens and taurine Bos taurus or indicine B. indicus cattle has been widely practiced throughout the yak geographical range, and gene flow is expected to have occurred between these species. To assess the impact of cattle admixture on domestic yak, we examin...

Presents results of a study carried out to analyse growth traits of the Dorper sheep. Data on 969 lambs collected over a 10-year period (1978 to 1987) at Magogo, Kenya were used in the study. Lamb traits studied were weights from birth to yearling and absolute growth rates between adjacent stages...

The effects of non-genetic factors on responses to gastrointestinal nematode infections were examined in artificially infected indigenous Horro and Menz lambs in the central highlands of Ethiopia. The experiment involved lambs of two sexes, infection and monitoring regimens (3 levels), dam parity...

Four cattle breeds indigenous to western and south-western Ethiopia - Abigar, Gurage, Horro and Sheko - were included in a study of the perceptions of smallholder cattle keepers regarding cattle management, production levels and constraints for production. A semi-structured questionnaire was used...

The accelerating demands of a growing human population and the pressures of economic development are affecting the security and survival of many indigenous African breeds. Until now, these breeds have been a stable part of their particular ecosystems for hundreds of years. There is an increasing ...
