用数学方法评估中草药对高龄蛋鸡生产性能的影响

Effects of Chinese Traditional Herbal Medicines on Production Performance of Aged Laying Hens

[目的]研究不同剂量中草药对高龄蛋鸡生产性能的影响。[方法]选用120只390日龄海兰褐蛋鸡,随机均分4组。分别用添加0.5%、1.0%、1.5%中草药的日粮饲喂①～③组鸡群,以饲喂未添加中草药日粮的鸡群为对照组(CK),连续给药15 d。观察各组每天的产蛋率、日产蛋量等生产性能指标。[结果]②组的产蛋率与CK差异极显著(P<0.01),提高了8.80%;③组的产蛋率与CK差异显著(P<0.05),提高了4.99%;②组和③组的日产蛋量与CK差异均极显著(P<0.01),分别提高了12.12%、6.82%;②组的料蛋比与CK差异极显著(P<0.01),降低了12.46%;③组的料蛋比与CK差异显著(P<0.05),降低了11.42%。其余指标无显著性差异(P>0.05)。[结论]1.0%中草药添加剂量可以明显提高高龄蛋鸡的生产性能。

[Objective] To study the effects of different doses of Chinese traditional herbal medicines on the production performance of aged laying hens.[Method] 120 390-day-old HY-line variety brown hens were randomly divided into four groups,four treatment groups were designed,0.5%,1.0% and 1.5% herbal medicines were added in the daily diet of hens in group 1-3 for 15 days in succession,the group without adding herbal medicine is CK.Then the laying rate and daily egg amount of hens in each treatment group were investigated.[Result] The laying rate of group 2 improved by 8.80% compared with the CK（P0.01）;the laying rate of group 3 improved by 4.99%（P0.05）;the daily egg amount of group 2 and group 3 improved by 12.12% and 6.82% respectively（P0.01）;the feed-egg ratio of group 2 reduced by 12.46%（P0.01）;while that of group 3 reduced by 11.42%.Other indexes showed no significant difference（P0.05）.[Conclusion] The dose of 1.0% herbal medicine in diet could obviously improve the production performance of aged laying hens.
