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...

Long-term response to feeding level in lactational performance of Boran (Bos indicus) and Boran X Holstein cows
This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...

Evidence for different nutrient partitioning in Boran (Bos indicus) and Boran x Holstein cows when re-allocated from low to high or from high to low feeding level
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...
