چکیده

the present research was conducted to estimate the dietary lysine (lys) requirement of growing female quail base on performance and carcass constitutes at 24 to 42 d of age. a dose-response diet mainly based on corn, corn gluten and soybean meal was used. lys content was minimized in dose-response diet (10 g/kg) while assuring the minimum levels of all other essential amino acids in a manner that would meet or exceed recommendation. this experiment was carried out in a complete randomized design arrangement with 6 dietary lys level; 10.0, 11.5, 13.0, 14.5, 16.0 and 17.5 g/kg, from 21 to 42 d of age. each treatment was consisted of 5 floor pens as replicate with 50 quail chicks. as a result of this study increasing dietary lys level, body weight, body weight gain and feed conversion ratio improved significantly (p
