The experiment was carried out with 20 intact Holstein male calves, 75 days old, with mean live weight of 76 kg, submitted to the same nursing system before starting the experiment. The objective was to evaluate the relative size of internal organs and viscera of these animals fed diets containing 45, 60, 75 and 90% of concentrate. Diets were composed of coastcross hay, ground corn grain, soybean meal and mineral mixture. The experimental design was a randomized blocks, with four […]

The objective of this work was to estimate the efficiency of metabolizable energy utilization (ME) for weight gain, and the requirements of metabolizable energy and total digestible nutrients in F1 Simental x Nellore bulls fed diets containing different concentrate levels. Twenty-nine animals averaging 17 of age and initial live weight of 354 kg were used. Five animals were slaughtered in the beginning of the experiment, as a reference, and the remainders were full fed and allotted to a completely randomized […]
