Insufficient feed supply is a major limiting factor for milk production in the tropics. The
aim of this study was to assess the effects of feeding level on live-weight and performance
of Zebu (Boran) and crossbred (Boran

Forty-eight heifers of two genotypes, Boran (Bos indicus) and Holstein×Boran, were allocated to three feeding levels equivalent to 1.0, 1.2 and 1.4 times calculated metabolisable energy requirements for maintenance (MEm). The experiment started at the onset of reproductive activity, when the Bora...

To study the efficiency of compensatory growth following different levels of feed restriction, 25 Borana bulls were blocked by weight and randomly allocated to five dietary treatments of ad libitum feeding for the entire period (control), maintenance feeding for 91 days (maintenance), 15 per cent...

Body measurements and slaughter weight of body component (carcass and edible non-carcass) of 63 zebu oxen were used in this trial. Out of these 9 of them were slaughtered at the initial stage of the experiment. The remaining 54 oxen were allocated to various levels of feeding or plane of nutritio...

Draft oxen have been used extensively by smallholders in many crop-livestock mixed production systems. In these system, crop production is totally dependent on oxen power. Other livestock have also been used for draft purposes depending on locality and circumstances. However, improved efficiency ...

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...
