Article Synopsis
- The study investigates the energy and protein needs of non-descript breed hair lambs raised in Brazil's semiarid conditions by using a comparative slaughter method with 60 lambs across three sex classes.
- The net energy requirement for maintenance was found to be uniform across sex classes, while specific formulas for net energy and protein requirements for weight gain were established and showed significant relationships with the lambs’ body weight.
- Results indicate that as the body weight of the lambs increases, their net energy requirement for growth rises and net protein requirement for growth decreases.
The effect of different feeding levels (ad libitum, 25 and 50 % restriction) and genotypes (½ Boer × ½ nondescript breed goats, Canindé, and Moxotó) on carcass quantitative characteristics and non-carcass components (NCC) were evaluated. Forty-five intact male goats were distributed in a 3 × 3 factorial design with five replicates. There was no effect of genotype on carcass weights and yields and retail cuts weights and yields (P > 0.
