Abstract

This experiment was conducted to investigate the effects of different levels of selenomethionine on reproductive performance in Daheng broiler breeders. A total of five hundred Daheng broiler breeders hens at age of 32 weeks were randomly allocated into 5 groups with 5 replicates per group and 20 hens per replicate. The control group was fed a basal diet, the experimental groups were fed the basal diet supplemented with 0.10,0.25,0.40 and 0.55 mg/kg selenium coming from selenomethionine, respectively. The experiment lasted for 6 weeks. The results showed as follows: 1) fertility of the incubated eggs in control group was significantly lower than that in 0.40 (P<0.05), 0.10 (P<0.01) and 0.25 mg/kg selenium groups (P<0.01). Hatchability of the incubated eggs in control group was significantly lower than that in all selenium groups (P<0.01). Hatchability of the fertilized eggs in control group and 0.40 mg/kg selenium group was significantly lower than that in 0.10 mg/kg selenium group (P<0.05). 2) Plasma progesterone level of the 0.10 mg/kg selenium group was significantly higher than that in the control group and 0.40 mg/kg selenium group (P<0.05). Egg Haugh unit in 0.10 mg/kg selenium group was significantly higher than that in 0.55 mg/kg selenium group (P<0.05). 3) There was no significant difference of the laying performance, level of plasma estradiol, egg shape index, eggshell thickness and strength of breeding eggs among all the groups (P>0.05). It is concluded that there is no significant influence on laying performance in Daheng broiler breeders when adding 0.10 to 0.55 mg/kg selenium coming from selenomethionine to the basal diet which contains 0.12 mg/kg selenium, and it can significantly improve the incubation performance of the breeding eggs in Daheng broiler breeders when adding 0.10 to 0.25 mg/kg selenium coming from selenomethionine.
