日粮能量、蛋白质水平对种公鸡繁殖性能的影响
Effects of dietary metabolized energy and protein levels on reproduction performance of Beijing-You chickens during the late reproductive period
摘要
Abstract
This experiment was conducted to study the effects of dietary metabolized energy （ME） and crude protein （CP） levels on reproduction performance of Beijing-You chickens during the late reproductive period. Ninety-nine 50- week-old Beijing-You breeder cocks were randomly assigned to 9 treatments with11 cocks in each treatment . Three levels of dietary ME （11.30,11.72,12.14 MJ/kg ） and CP （12% ,14% ,16%） were assigned to the 9 treatments by 3 × 3 factorial experimental design. The results showed that the growth and reproductive performance were not significantly affected by CP level （ P~0.05）, but sperm motility tended to be improved with lower dietary CP level. The feed intake and sperm motility rate in 12.14 MJ/kg ME level were significantly higher than that of the other groups （ P〈 0.05）. The deformity rate of treatment 9 was significantly higher than the others. This result was verified by the incubation tests. Fertilization rate, hatching rate and healthy chick rate of the treatment 8 with 12.14 MJ/kg ME and 14% CP was the most optimized. 12% CP and 11.72 MJ/kg ME level were suggested for the diet of late reproductive period of Beijing-You chicken. Other local varieties which have similar characteristics can refer to.关键词
