Where VRI is a function of basal roughage quality (nitrogen and fibre (NDF) contents, rumen dry matter degradability), CF basal is the correction factor for other attributes of the roughage (cropping and processing methods and forms of offer), CF sup is the correction factor for supplement attrib...

Studies the broad groups of cattle in Africa in relation to the main ecological zones. Indicates the possibilities for bringing about changes through application of animal breeding techniques. Reviews past cattle breeding research in Africa. Summarises ILCA's work with national research organisat...
The classification of bovine immunoglobulins is similar to that of nonruminant mammals, namely IgM, IgA, IgG<sub>1, IgG<sub>2 and IgE. There are minimal differences between IgG<sub>1 and IgG<sub>2 in complement fixation, ability to mediate passive cutaneous anaphylaxis, phagocytosis of coated er...

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...

Microsatellite loci are the markers of choice in pedigree analysis and population genetics studies. In closely related species, cross-species amplification of loci may be used instead of the cloning of loci. Previously, successful cross-species amplification of a set of cattle (Bos taurus) micros...

Bovine trypanosomiasis caused by pathogenic trypanosomes, and cyclically transmitted by tsetse flies, is considered to be a major disease constraint to livestock production in sub-Saharan Africa, preventing full use of the land to feed the rapidly increasing human population. Privatisation of vet...

Quantifies some of the benefits to range resource use and human food supply from multiple species stocking in African livestock systems. Gives examples of the use of range resources by camels, cattle, goats and sheep in terms of the percentages of total time spent on feeding. Presents productivit...
