摘要
实验选用3日龄AA肉鸡14000只，随机分成2组，实验组／3服功能型微生态制剂，空白对照组不饲喂任何微生态制剂，全程跟踪监测。结果表明，肉鸡在口服功能型益生菌制剂后表现出三大特点：（1）肉鸡生长加快，鸡群整齐度与均匀度有所改善，出栏平均重提高9．5％；（2）肠道环境有所改善，饲料利用率提高，实验组比对照组料肉比降低2．16％；（3）实验组鸡群可提前3～5d出栏。
A total of 14 000 3-day-old AA broilers were randomly divided into two groups. The experimental group were fed with the functional microorganism praeparatum, and the control group were not treated. Restths showed that the broilers fed with functional microorganism praeparatum present three outstanding features：First, promoting broilers to grow, improving regularity and uniformity of the broilers. The addition of probiotics tO the basal diet increased the body weight by 9.5%. Second, improving intestinal tract environment, increase feed nutrient gain ratio, reduce the fodder-meat rate by 2.16%. Finally ,the time of the group of additive was earlier than control group in out the colunm.
