The objective of this trial was to evaluate the non-integrant body components of the carcass from young bulls slaughtered at 14-16 months of age, fed different concentrate levels in the diet. The animals were feedlot finished until reaching 400 kg of body weight. Sixteen bulls were randomly distributed into four treatments: 22; 40; 59 or 79% concentrate in the diet. The initial average age and weight were 9.3 months and 192.4 kg, respectively. The empty body weight (EBW) and carcass […]

The objective of this trial was to evaluate the components of non integrate body components of carcass 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 3.18 […]

The objective of this experiment was to study the effects of feeding whole goat milk or fermented cow colostrum supplemented or not with soy oil and with or without the growth promoter Zeranol on performance of kid goats. Twenty-four Alpine kid goats assigned to a completely randomized design in a 3 x 2 factorial arrangement were used in this trial. The following variables were investigated: weight gain, intakes of dry matter and concentrate, feed conversion, and organ sizes. Significant differences […]
