摘要:

本研究旨在探究日粮中添加溶菌酶对产蛋后期蛋鸡生产性能、脏器质量、血清生化指标及脂代谢指标的影响,选取50周龄的健康海兰褐蛋鸡,随机分为4组,每组设3个重复,每个重复12羽蛋鸡。对照组饲喂基础日粮,试验组分别在基础日粮中添加300、500和700 mg·kg-1溶菌酶。预试期14 d,正式试验期30 d。结果表明,与对照组相比,添加300和500 mg·kg-1溶菌酶在54周龄和55周龄时显著(p<0.05)提高蛋鸡产蛋率,同时,添加300 mg·kg-1溶菌酶的平均蛋重在55周龄时也显著高于对照组。日粮添加溶菌酶对蛋鸡脏器质量、血清生化指标、脂代谢指标无显著影响。综上所述,日粮中添加溶菌酶能够提高蛋鸡的生产性能,连续添加28 d后效果显著。300 mg·kg-1的溶菌酶添加量为本试验的最优剂量。

Abstract:

The aim of this study is to investigate the effects of basal diet supplemented with lysozyme on the production performance,viscus weight,serum biochemical indicators,and lipid metabolism indicators of laying hens in the late stage of egg production. Healthy Hyline brown laying hens were randomly divided into four groups at 50 weeks of age,with three replicates in each group and 12 hens in each replicate. Control group was fed with the basal diet,and the experimental groups were fed with the basal diet supplemented with 300,500 and 700 mg·kg-1 lysozyme,respectively. The pre-trial period lasted for 14 days,and the experimental period lasted for 30 days. The results showed that compared with the control group,the supplementation of 300 and 500 mg·kg-1 lysozyme significantly(p<0.05)increased the egg production rate of laying hens at 54 and 55 weeks of age,and the average egg weight of 300 mg·kg-1 lysozyme treatment at 55 weeks of age was also significantly higher than that of the control group. Basal diet supplemented with lysozyme had no significant effect on viscus weight,serum biochemical indicators,and lipid metabolism indicators of laying hens. In conclusion,basal diet supplemented with lysozyme can improve the production performance of laying hens,and the effect is significant after 28 days of supplementation. The optimal dosage for this experiment is 300 mg·kg-1 lysozyme.
