Reports the feeding preferences of Glossina species at sites of the African Trypanotolerant Livestock Network. Estimates tsetse challenge and relates the results with trypanosome prevalence in cattle. Examines the relationship between tsetse challenge using linear regression analysis. Also examin...

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...

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...
Describes the information and documentation services at ILCA headquarters in relation to information dissemination and the service by ILCA on data analyses and interpretation for national research organizations. Gives examples of importand breed groups.
Postpartum body weight dynamics of zebu and crossbred cows in relation to postpartum reproduction was studied using data from the Bako Agricultural Research Centre. Body weight at calving, first postpartum oestrus, first service and conception were analysed using the General Linear Model which in...

The effect. of genotype (50% 75% and 87.50, levels of milk (2 and 3 1/day) and types of housing (Barn and Hutch) were examined using 38 Boran x Friesians crossbred calves (Bos Taurus x Bos indicus). Calves were offered supplement diet (180 g/kg CP and 100g/kg roughage) and were weaned until their...
