| Abstract: | 1. Two feeding experiments were conducted to determine the crude protein requirement of laying Japanese quail. Birds were fed to provide 293 kJ ME and 2, 3, 4, 5, 6 or 7 g protein/d. 2. As protein intake increased from 2 to 5 g egg production increased. 3. Quadratic relationships between protein intake and egg production and protein intake and egg weight were derived. 4. To maintain a production of 90 eggs/100 bird d and an egg weight of 9.3 g required 4.9 g protein and approximately 264 kJ ME/d. |
