In an experiment lasting from 1.5 years before, first calving until third parturition, 24 purebred indigenous Bos indicus (Boran) cows and 24 Boran crosses will; Holstein (proportionately 0.50 and 0 75 Holstein blood level) were given a diet composed of Bermuda grass hay and wheat bran (0 65: 0 3...

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...

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...

This paper Reports on both the individual and combined effects of age at first caving (AFC) and live weight at first calving (LWFC) for crossbred heifers (Friesian x Zebu) on first lactation Milk yield. Optimal health and nutrition management was followed. Fifty one heifers were allocated to youn...
