摘要

本研究旨在评估饲粮氯化胆碱对白来航蛋种鸡生产性能和血清生化指标的影响。选取240只48周龄白来航蛋种鸡，随机分成4组，每组5个重复，每个重复12只蛋种鸡。饲喂玉米-豆粕型基础饲粮，氯化胆碱添加水平分别是450、750、1 050和1 650 mg/kg，试验期13周。结果表明：1）各组蛋种鸡产蛋率差异不显著（P>0.05），450 mg/kg氯化胆碱组蛋种鸡成活率最低，与其他添加组有显著差异（P<0.05）。2）各组除蛋黄颜色（P<0.05），其他蛋品质指标差异不显著（P>0.05），750 mg/kg氯化胆碱组的鸡蛋蛋黄颜色最深；各组鸡蛋储存期差异不显著（P>0.05）。3）750 g/kg氯化胆碱组的蛋种鸡受精蛋孵化率最高，显著高于其他各组（P<0.05）。4）750 mg/kg氯化胆碱组的血清白蛋白含量显著高于其余各组（P<0.05），750 mg/kg氯化胆碱组的血清尿素氮、尿酸和甘油三酯含量显著低于450 mg/kg氯化胆碱组（P<0.05）。研究提示，适宜的氯化胆碱添加水平（750 mg/kg）可提高蛋种鸡产蛋后期的成活率和受精蛋孵化率，降低血清尿素氮、尿酸和甘油三酯含量。

Abstract

This study was aimed to evaluate the effects of choline chloride on performance and serum biochemical 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 other 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 chloride 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.

Key words： choline chloride; white Leghorn breeding hens; hatchability; livability; urea nitrogen; urea acid; triglyceride
