Three experiments were conducted in successive years on crossbred suckler cows on a farm 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). The effects of milking once daily and supplementation (2 kg/h...

In a field study in Kenya, 55 plots in a Pennisetum purpureum sward were cut in rotation to give a 55-d regrowth cycle. After cutting, each plot was weeded and given 6.3 kg N + 4.5 kg P/ha. The daily DM production varied from 25 (dry season) to 178 kg DM/ha (rainy season). The mean DM yield after...

To evaluate the Weitzman approach for assessing alternative conservation strategies for breed ( population ) diversity, we used genetic distance measures between 49 African cattle breeds divided into two groups of 26 taurine ( Bos taurus ) and sanga ( Bos taurus×Bos indicus ) breeds and 23 zebu ...

The indirect MAP 1B ELISA based on the recombinant MAP 1B fragment of the immunodominant MAP 1 protein of Ehrlichia ruminantium is considered to be the most sensitive and specific assay for the serodiagnosis of heartwater. In this study, we evaluated its reliability in detecting exposure to E....
Because major histocompatibility complex (MHC) genes play a major role in the development of acquired immune responses, it is essential to obtain comparative information on their organisation, expression and possible functional dichotomies in different species. In human, three classical, polymorp...
We describe the development of a polymerase chain reaction (PCR)-based approach for analysis of genetic diversity at the DQA loci in African Bos indicus and Bos Taurus cattle. This approach, equally effective in European and Asian cattle breeds, detects the presence or absence of DAQ1 and most du...
