摘要
文章旨在研究益母草粉对蛋鸡生产性能、血清免疫及抗氧化性能的影响。试验将600只40周龄、体重和产蛋率相近的海兰褐壳蛋鸡随机分为4组,每组5个重复,每个重复30只。试验期间,对照组参考蛋鸡营养标准(NRC)配制基础日粮,其余3组分别在基础日粮中添加1、2、3 g/kg益母草粉。试验为期30 d。结果表明:(1)与对照组相比,2 g/kg益母草粉组产蛋率显著提高9.22%(P <0.05),料蛋比显著降低14.75%(P <0.05);1、2、3 g/kg益母草粉组破蛋率显著降低37.95%、42.66%、40.44%(P <0.05)。2)与对照组相比,2、3 g/kg益母草粉组血清免疫球蛋白A含量显著提高60.48%、65.26%(P <0.05),3 g/kg益母草粉组血清免疫球蛋白G含量显著提高34.99%(P <0.05),3 g/kg益母草粉组血清免疫球蛋白M含量显著提高62.74%(P <0.05)。3)与对照组相比,3 g/kg益母草粉组血清总抗氧化能力显著提高了40.50%(P <0.05),2、3 g/kg益母草粉组血清丙二醛含量显著降低21.42%、22.78%(P <0.05)。结论 :基础日粮+2 g/kg益母草粉能提高蛋鸡生产性能;基础日粮+3 g/kg益母草粉能改善蛋鸡血清免疫及抗氧化性能。
This experiment aims to investigate the effects of motherwort powder on the production performance,serum immunity,and antioxidant performance of laying hens.Select 60040 week old Hailan brown shell laying hens with similar body weight and egg laying rate,and randomly divide them into 4 groups,with 5 replicates in each group,with 30 replicates per replicate.During the experiment,the control group was fed a basic diet according to the laying hens nutrition standard(NRC),while the other three groups were fed a basic diet of+1 g/kg,2 g/kg,and 3 g/kg of motherwort powder.The experiment lasted for 30 days.The results showed that:(1)Compared with the control group,the egg production rate of the 2 g/kg motherwort powder group significantly increased by 9.22%(P<0.05),the 2 g/kg motherwort powder group significantly reduced the feed to egg ratio by 14.75%(P<0.05),the egg breaking rate of the 1,2 and 3 g/kg motherwort powder groups significantly decreased by 37.95%,42.66%,and 40.44%(P<0.05).(2)Compared with the control group,the serum immunoglobulin A content in the 2 and 3 g/kg motherwort powder groups significantly increased by 60.48%and 65.26%(P<0.05),the serum immunoglobulin G content in the 3 g/kg motherwort powder group significantly increased by 34.99%(P<0.05),the serum immunoglobulin M content in the 3 g/kg motherwort powder group significantly increased by 62.74%(P<0.05).(3)Compared with the control group,the serum total antioxidant capacity of the 3 g/kg motherwort powder group was significantly increased by 40.50%(P<0.05),the serum malondialdehyde content in the 2 and 3 g/kg motherwort powder groups significantly decreased by 21.42%and 22.78%(P<0.05).Conclusion:Basic diet+2 g/kg motherwort powder can improve the production performance of laying hens;The basic diet of+3 g/kg motherwort powder can improve the serum immunity and antioxidant performance of laying hens.
