Ensuring that locally adopted breeds are a functional part of production systems is the most national and sustainable way to conserve animal genetic resources. This can only be possible if sustainable breeding strategies for such animals are developed which take into account their economically im...
A total of 1443 records of preweaning traits of calves in a dairy herd in coastal lowland Kenya were used to estimate crossbreeding parameters in a regression analysis. In this herd, the Ayrshire (A), Brown Swiss (B) and Sahiwal (S) breeds have been used in a 3-breed rotation crossbreeding system...
An individual animal model was fitted to data from a crossbred herd in the lowland coastal tropics of Kenya to estimated breed cross means for a total of 25 genotypes having different proportions of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) genes. These means were then regressed...
The study reports the effect of incorporating risk in the derivation of economic values for traits of the breeding goal of Small East African goats under the pastoral production system. A model previously used to derive conventional economic values was revised ...
