几种叶黄素方剂对高温高湿环境中蛋鸡行为和生产性能的影响

Effects of Several MAR Mixture Compounds on Behavior and Production Performance of Laying Hens in High Temperature and Humidity Environment

为探讨几种叶黄素方剂对高温高湿环境中罗曼粉壳蛋鸡的抗热应激效果,选取216只47周龄的健康、体质量及生产性能相近的罗曼粉壳蛋鸡,随机分为6组(常温对照组、高温对照组、高温叶黄素组和叶黄素合剂Ⅰ、Ⅱ、Ⅲ组),对照组饲喂基础日粮,高温叶黄素组和叶黄素Ⅰ、Ⅱ、Ⅲ组则在基础日粮的基础上添加120 mg/kg叶黄素、叶黄素合剂Ⅰ(120 mg/kg万寿菊叶黄素+1 g/kg甜菜碱)、叶黄素合剂Ⅱ(120 mg/kg叶黄素+200 mg/kg维生素C)和叶黄素合剂Ⅲ(120 mg/kg叶黄素+2 g/kg中草药),测定不同叶黄素方剂对高温高湿环境中蛋鸡行为和生产性能的影响。结果表明,叶黄素合剂能有效降低高温环境中蛋鸡死淘率,改善蛋鸡的健康状况。与高温对照组相比,叶黄素组与叶黄素合剂Ⅰ、Ⅱ、Ⅲ组平均日采食量分别提高了1.59%(P<0.05)、6.07%(P<0.01)、11.12%(P<0.01)、10.39%(P<0.01);产蛋率分别提高0.91%(P>0.05)、8.31%(P<0.01)、13.93%(P<0.01)、5.56%(P<0.01);破壳率分别降低了7.38%(P>0.05)、44.26%(P<0.01)、59.02%(P<0.01)、17.21%(P<0.01);料蛋比分别下降0.40%(P>0.05)、6.85%(P<0.01)、6.05%(P<0.01)、4.03%(P<0.05);死淘率分别降低了12.51%、74.98%、87.49%、50.00%。可见,几种叶黄素方剂均具有缓解热应激作用,以叶黄素合剂Ⅱ效果最佳。

In order to investigate the effects of different lutein mixture compounds on behavior and per-formance of laying hens in high temperature and humidity environment,two hundred and sixteen 47-week-old lohmann laying hens were randomly divided into normal control group,high temperature control group, high temperature lutein group and lutein compound Ⅰ—Ⅲ groups. The control group was fed with basal diets,while the lutein group and lutein compound Ⅰ—Ⅲ groups were fed with diets supplemented 120 mg/kg lutein and lutein compound Ⅰ—Ⅲ（120 mg/kg lutein＋1 g/kg betaine,120 mg/kg lutein＋200 mg/kg VC,120 mg/kg lutein＋2 g/kg Chinese herb） . The results showed that lutein mixture compounds could decrease the mortality and improve the healthy condition of hens significantly. Compared with high temperature control group, the feed consumptions of hens in letein group and lutein compound Ⅰ—Ⅲgroups increased by 1 . 59%（ P 0. 05）,8. 31%（P0. 05）,44. 26%（P 0. 05）, 6. 85%（P〈0. 01）,6. 05%（P〈0. 01）,4. 03%（P〈0. 05）,and the mortalities decreased by 12. 51%, 74. 98%,87. 49%,50. 00%. Therefore,all the three lutein compounds could relieve hens’ heat stress, and MAR compound Ⅱtook the best results.
