In this study, it was evaluated the productive performance of nine Zebu × Holstein crossbred calves in comparison with nine Holsteins calves for veal production. All animals were maintained in the similar environmental conditions, management and feeding, with individual measurement of dry matter intake. The evaluation measurements of the development of animal, as feed conversion ratio make possible to compare between the treatments, using a completely randomized design. The Zebu × Holstein calves showed higher values of hearth girth growth […]

The objective of the experiment was to evaluate the carcass quantitative characteristics of feedlot finished steers, slaughtered at 13-14 months of age. Sixteen calves with nine months of age and average initial weight of 220 kg, being eight Aberdeen Angus – AA and eight Hereford – HE, were used. The animals were submitted to two levels of energy, 3.07 or 3.18 Mcal/kg of DM. The complete randomized experimental design was used, with a 2 x 2 factorial arrangement (two breeds […]
