Effects of Choline Chloride on Performance and Serum Biochemical Indexes of White Leghorn Breeding Hens in Late of Peak Production
摘要
Abstract
This study was aimed to evaluate the effects of choline chloride on performance and serum biochemi-cal indexes of white Leghorn breeding hens in late of peak production. A total of 240 white Leghorn breeding hens,48-week-old,were randomly divided into 4 groups with 5 replicates in each group and 12 breeding hens in each replicate. Hens in the four groups were fed corn-soybean basal diets supplemented with 450,750, 1 050 and 1 650 mg/kg choline chloride,respectively. The experiment lasted for 13 weeks. The research showed as follows:1)no significant difference of laying rate was found among all groups( P>0.05),and the livability of the 450 mg/kg choline chloride group was the lowest,which had a significant difference from oth-er groups( P<0.01). 2)Except the yolk color( P<0.05),no significant differences of egg quality were found among all groups(P>0.05). Yolk color of the 750 mg/kg choline chloride group was the highest. Choline chloride added level could not improve the ability of storing eggs( P>0.05). 3)The 750 mg/kg choline chlo-ride group had the highest fertile hatchability than other groups( P<0.05). 4)The 750 mg/kg choline chloride group had the highest serum albumin content than other groups( P<0.05). Serum urea nitrogen,urea acid and triglyceride contents of the 750 mg/kg choline chloride group were significantly lower than those of the 450 mg/kg choline chloride group( P<0.05). The research implies that the appropriate choline chloride added level(750 mg/kg)can improve the livability and fertile egg hatchability,reduce serum urea nitrogen,urea acid and triglyceride contents of breeding hens in late of peak production.关键词
