| Abstract: | 1. The effects of including copra meals from different sources in nutritionally-balanced broiler chick diets were compared. A meal screw press-expelled twice to contain 75 g residual lipid/kg produced a lower growth rate than a meal pressed once to contain 220 g lipid/kg. 2. Chicks fed copra meal at 400 g/kg diet had a higher growth rate on a diet formulated to contain 12.4 g lysine/kg and 8.3 g methionine+cystine/kg than on a diet containing 13.5 and 9.0 g/kg of the respective amino acids; however, in a second experiment performance of chicks was unaffected when the low amino acid, low-oil copra meal-based diet was supplemented with synthetic amino acids. |
