This study was conducted to develop equations to predict chemical composition of head, limbs, hide and blood in cattle. A database containing 335 animals from 10 trials, with 221 Nellore, 38 Nellore-Simmental and 76 Nellore-Angus (96 steers, 118 heifers and 121 bulls) animals was used. Models were constructed to estimate water, ether extract (EE), crude protein (CP), ash and macrominerals (calcium, phosphorus, magnesium, sodium and potassium) in the non-carcass parts of cattle. A stepwise procedure was conducted to determine the […]

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 […]

Thirty two Holstein black and white type bull calves averaging 75 days of age and initial 78 kg LW, divided into two slaughter groups (group 1: 16 animals slaughtered with 190 ± 10 kg LW and group 2: 16 animals slaughtered with 300 ± 10 kg LW) were allotted to a completely randomized design to evaluate the effects of crescent dietary levels of concentrate on the quantitative traits of the non integrate body parts of the animal carcass and the […]
