Effects of menotropin on laying performance and egg qualitative characters in Japanese quail (Couturnix japonica)

In this research Evaluate 96 Japanese quail female 9 month age (in egg drop production period) in 40 days. These birds grouped in 3 experimental groups contain human menotropin gonadotropin (HMG) injection in 0, 180 and 360 mg/kg body weight bird in day during 10 days in breast muscle, With 4 replicates and 8 birds in each replicate. This bird divided by randomized completely block design. During injection and post injection periods, calculated laying performance and qualitative characters after collecting data in each period. Results shown both doses from HMG significantly increased egg weight, albumin percent, egg content weight, egg production percent and decrease feed conversion ratio in both periods (P
