Thirty-six Angus ´ Nelore crossbred young bulls averaging 8 month of age and 240 kg BW and fed diets with high moisture corn or sorghum during 172 days were allotted to two experimental treatments (where the main energy source of total diet was composed by high moisture corn – HMC or sorghum – HMS) to evaluate the differences on carcass and meat quality of young cattle. The experiment was analyzed as a completely randomized design. There were similarity for average […]

The differences on performance of young cattle fed diets with high moisture corn or sorghum were evaluated in two treatments, where the main energy source of the total diet was composed of high moisture corn (HMC) or sorghum (HMS). Ninety Angus ´ Nelore crossbred young bulls, averaging 8 month of age and 240 kg BW and fed during 172 days were allotted to two experimental treatments as a completely randomized design. No treatment effect on average daily gain, total weight […]

This research aimed to estimate the maintenance requirements of net energy (NEm) and metabolizable energy (MEm), and the changes in body and gain composition of confined adults non-pregnant and non-lactant beef cows. Thirty six cows were used, 12 were Nellore (NEL), 12 F1 Brown Swiss-Nellore (BSN) and 12 F1 Red Angus-Nellore (RAN). The comparative slaughter method was utilized to estimate the changes of animal body chemical composition during the experimental period. Four animals from each breed group were randomly allocated […]

The direct effect of Red Angus (), computed as deviation from the direct effect of Nellore (), and the effects of individual () and maternal () heterozygosity, resulting from crossing these breeds were estimated. The multiple regression method was used to analyze birth weight (PNT), weaning weight (PDS), yearling weight (P12M), and for the daily weight gain from birth to weaning time (GMD_ND) and from weaning to 12 months (GMD_DA). A total of 410 calves from the groups of Nellore, […]
