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...

Five mathematical models were evaluated for their ability to describe ruminal degradability profiles of protein sources composed of herbaceous legumes, browse species and oilseed cakes. Degradability constants of dry matter, organic matter, nitrogen and neutral detergent fiber of the feeds were t...
