Analyses trends in genetic and environemntal components of performance, to estimate levels of inbreeding and to quantify its effects on performance in order to identify which of these factors is responsible for the decline in performance at the Stud. Presents an evaluation of long-term breeding p...

A dynamic performance model was integrated with a model that optimised culling and insemination policies in dairy herds using dynamic programming. The performance model estimated daily feed intake, milk yield and body weight change of dairy cows on the basis of availability and quality of feed an...

Trypanosomosis is one of the major constraints on animal production in areas of Africa which have the greatest potential for significant increases in domestic livestock populations and livestock productivity. While the eradication of trypanosomosis from the entire continent is an unrealistic goal...

Three experiments were conducted in successive years using 32, 53 and 74 crossbred suckler cows respectively, in a semi-arid area close to Nairobi, Kenya. The cows were mated seasonally to calve approximately 1 month before the rainy season (March to May). A 2 X 2 factorial experimental design wi...

Three experiments were conducted in successive years using 32, 53 and 74 calves of crossbred suckler cows in a semi-arid area close to Nairobi, Kenya. A 2 X 2 factorial experimental design was used with milking and supplementation (2 kg concentrate/head per day) as the main treatments. The effect...
