Abstract
This experiment was conducted using 204 day-old Japanese quail chicks to evaluate the effect of different levels of dietary choline on growth performance and carcass characteristics. The experimental diets consisted of 4 levels of choline: 1000, 1500, 2000 and 2500 mg/kg diet. Each dietary treatment was assigned to 3 replicate groups of 17 chicks and the experiment lasted 35 days. Live body weight and body weight gain was significantly (P< 0.01) increased with increasing choline level from 1000 to 2000 mg/kg diet at all different ages, except body weight gain was not affect by dietary choline levels during 21-42 days of age. Feed consumption and feed conversion ratio were affected by the different levels of choline at the different ages (P<0.05), vs. feed conversion ratio was not significantly affect by dietary choline levels during 21-42 days of age. In conclusion, the obtained results showed that the diet containing 2000 mg/kg choline diet is recommended for feeding growing Japanese quail during the fattening period (7 to 42 days of age).
