This investigation was carried out to determine body composition of protein, fat, and energy as well as nutritional requirements of protein and energy for maintenance and weight gain of Morada Nova Lambs. Thirty lambs averaging 15 kg of initial body weight (BW) were used in this trial. To determine the body composition using the comparative slaughter approach six lambs were slaughtered at 15 kg (reference animals), six at 20 kg (intermediary slaughter), and the remaining were distributed in one of […]
