The effect of five dietary concentrate levels on the gastrintestinal contents and internal organs weight of Nellore bulls was evaluated. Twenty-five animals averaging 330 kg and 20 months of age were allotted to a completely randomized design, with five treatments constituted by different dietary concentrate levels in dry matter (25.0, 37.5, 50.0, 62.5, and 75.0%). The animals, when reached the pre-established slaughter weight of 450 kg, were slaughtered and the organs and viscera weights were recorded. Regression equations were fitted […]
