Feeding and Growth of Japanese Quail (coturnix C. Japonica) Chicks with Unpredictable Food
We investigated the effect of unpredictable feeding times on feeding activity and body mass gain in fast growing Japanese quail (Cotumix c. japonica) from 7 to 31 d of age. Quail chicks were subjected to a long day length (18L:6D) with ad libitum food during (1) 17.5 h of the light period, starting 0.5 h after lights-on (group A, n = 14), (2) 6 h of the light period, starting 0.5 h after lights...

متن کاملEnzyme on Japanese Quail (Coturnix japonica) Performance
An experiment was conducted to study the eff ect of phytase enzyme (Natuphos 500) supplementation in Japanese quail (Coturnix japonica) (3 to 45 days of age) on body weight, carcass performance, percentage of tibia bone ash and tibia phosphorus. Data were analyzed as a completely randomized design arranged with fi ve levels (150, 300, 600, 1200 and 2400 FTU/Kg) of phytase enzyme as treatments 1...
