Abstract

This experiment was conducted to evaluate the effects of daidzein on laying and reproductive performance of broiler breeders. Two hundred and forty 43-week-old broiler breeders S2 hens with similar body weight and laying rate were randomly divided into 4 groups with 6 replicates per group and 10 hens per replicate, which were fed basal diet added with daidzein 0 (control group), 5, 10 and 20 mg/kg, respectively. Twenty health S2 cocks were selected for semen collection. And use artificial insemination of mixed semen in experimental chickens. The experimental period lasted for 15 weeks. The results showed as follows:compared with the control group, 1) diet added with daidzein had no significant effects on the body weight gain, feed intake and mortality of S2 broiler breeders (P>0.05). 2) Diet added with daidzein had significant effects on laying rate (P<0.05). Laying rate of 10 mg/kg group was increased by 4.1% (P<0.05), daily egg mass was increased by 3.5% (P<0.05), and 10 mg/kg group was the best group. The ratio of feed to egg of 5 and 10 mg/kg groups was decreased by 8.0% and 11.2% (P<0.05), respectively. 3) Fertilized rate, hatchability and health chicken rate of 10 mg/kg group were increased by 13.1%, 20.5% and 5.8% (P<0.05), respectively. Therefore, the diet added with daidzein can significantly improve the laying and reproductive performance of broiler breeders, particularly for the diet added 10 mg/kg daidzein.
