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...

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...
