The paper reviews the evidence of genetic resistance to endoparasites both within and between breeds of sheep and goats and assesses the possibilities of breeding for increased resistance. In light of this evidence, ILCA has developed a Pan-African research programme to investigate and characteri...

About 30% of all farm animal breeds worldwide are at risk of extinction. To prevent this irreversible erosion of genetic diversity, the limited funds available for conservation need to be allocated in the most efficient way. Applying the diversity concept of Weitzman [Quart. J. Econ. CVII (1992) ...

A comparative study on the response of four indigenous cattle breeds of Ethiopia, namely Abigar, Horro, Sheko and Gurage, to natural challenge of trypanosomosis in the Tolley–Gullele area of the Ghibe valley has been undertaken from August 2000 until August 2004. Fifty female yearlings each of Ho...

The genetic variation in 10 indigenous Caucasian sheep breeds was studied with 14 micro-satellite loci in order to determine the genetic diversity among and between the breeds. Five breeds from Asia, five breeds from Europe and one breed from Africa, were included in order to study any relationsh...

Agriculture is the largest contributor to the economies of many African countries, generating more than half of the annual Gross Domestic Product (GDP) for many of these countries. The livelihoods of most rural and low-income communities in these countries are to a large extent based on agricultu...

In this study we compare revealed and stated-preference approaches to value traits of cattle in Kenya. The premise is that much can be learnt about non-market values of indigenous animal genetic resources (AnGR) from the use of multi-attribute stated-preference methods, if these compare well with...

Body weight (LW), condition score (BCS), tail length on inner side of tail (TL), tail volume measured by water displacement (TV) and tail circumference (TC), width (TW) as well as thickness at the base (TT) were measured in live Menz (n=303) and Horro (n=151) sheep to determine their possible use...
