Hybridization between wild and domestic bovine species occurs worldwide either spontaneously or by organized crossing. We have analysed hybridization of banteng (Bos javanicus) and zebu (Bos indicus) in south-east Asian cattle using mitochondrial DNA (PCR-RFLP and sequencing), AFLP, satellite fr...

We report for the first time, and for the whole of sub-Saharan Africa, the geographical distribution and the frequency of an indicine and a taurine Y specific allele amongst African cattle breeds. A total of 984 males from 69 indigenous African populations from 22 countries were analysed at the m...

A conceptual framework for evaluating cross-breeding programmes in sub-Saharan Africa is developed based on a Kenyan case study. It depicts livestock production as a system where farm animals, plants, land and water are interlinked in particular ways and are also interlinked with the environment....

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...

Results from 80 Reports in the literature on crossbreeding in the tropics were summarised to study the relationship between dairy performance and proportion of exotic genes. Grades higher than 1/2 exotic did not perform any worse than the Fl in all traits, except calving interval which was longer...
