摘要
试验旨在研究热应激条件下黄羽肉鸡饮用发酵菌液对其生产性能的影响。选取65日龄、体重接近的黄羽肉鸡1 088只,随机分成2组,每组有8个重复,每个重复68只鸡。在热应激的条件下,对照组肉鸡饮用正常自来水,试验组饮用发酵菌液,试验期10 d。研究结果表明,在热应激条件下黄羽肉鸡饮用发酵菌液能显著改善肉鸡日均采食量、日均增重及耗料增重比(P<0.05),但对成活率无显著影响(P>0.05)。综上所述,在热应激条件下,黄羽肉鸡饮用发酵菌液能有效改善其生长性能。
The effects of drinking fermented microbial complexes on the performance of yellow-feathered broilers under heat stress were studied.A total of 1 088 63-day-old yellow-feathered broilers with similar weight were selected and randomly divided into 2 groups,with 8 replicates in each group and 68 chickens in each replicate.Under the condition of heat stress,broilers in the control group drank normal tap water,and those in the experimental group drank fermented bacterial solution.The experiment lasted for 10 days.The results showed that under heat stress conditions,drinking fermented microbial complexes could significantly improve the average daily feed intake,average daily gain and ratio of feed to gain(P<0.05),but had no significant effect on survival rate(P>0.05).In conclusion,the growth performance of yellow feather broilers can be effectively improved by drinking fermented microbial complexes under heat stress.
