| Popis: | 1. Calcium and phosphorus requirements of growing female Japanese quail during 4 and 5 weeks of age were estimated in a 4 × 3 factorial experiment comprising 5, 7, 9 and 11 g calcium and 5, 6 and 7 g phosphorus/kg diet. 2. Responses in weight gain, bone ash, food intake and food : gain ratio showed no significant differences due to varying dietary calcium and phosphorus concentrations. 3. It appears that growing Japanese quail require not more than 5 g calcium and not more than 5 g phosphorus (2 g available phosphorus)/kg diet (398 mg calcium and 398 mg phosphorus or 159 mg available phosphorus MJ ME). |
