The objetive in this experiment was to evaluate carcass and beef quantitative and qualitative characterstics from young bulls, slaughtered at 14-16 months of age and fed diets containing different concentrate levels. It was used sixteen Charolais- Nellore crossbreed non-castrated young bulls and fed diets containing 22; 40; 59 or 79% of concentrate. The animals were complete randomly distributed, with four replicates per diet. Initial age and body weight of the animals were 9.32 months and 192.44 kg, respectively. The animals […]

The objective of this trial was to evaluate the carcass physical composition and meat qualitative characteristics of males of two categories, steers (slaughtered at 22.8 months old) and young steers (slaughtered at 15.2 months old), from two genetic groups, 5/8 Charolais (CH) 3/8 Nellore (NE) and 5/8NE 3/8CH, and to evaluate the relationship among the variables studied. The animals were fedlot finished until reaching 430 kg. The diet, roughage:concentrate ratio of 60:40 (dry matter basis), contained 10.25% crude protein and […]
