蛋氨酸硒对大恒肉种鸡繁殖性能的影响
Effects of Selenomethionine on Reproductive Performance in Daheng Broiler Breeders
摘要
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.关键词
