摘　　要：试验旨在比较日粮方案对饲养于吉尔吉斯斯坦的肉仔鸡生长性能和全净膛率的影响。选取1日龄罗斯308肉仔鸡10 000只(公母各占1/2),随机分为对照组和试验组,分别饲喂试验基地的原有日粮和修订后的日粮。每组10个重复,每个重复500只,试验期42 d。试验组三个饲养阶段肉仔鸡的期末体质量均显著高于对照组(P<0.05)。试验组肉仔鸡三个饲养阶段及全程的体增质量、料重比及单位增重成本均显著优于对照组(P<0.05)。试验组肉仔鸡全净膛率较对照组提高2.1个百分点,差异达到显著水平(P<0.05)。综上所述,修订后的日粮方案优于原日粮方案。The purpose of the experiment was to compare the effects of dietary schemes on the growth performance and total evisceration rate of broilers raised in Kyrgyzstan.Ten thousand 1-day-old Ross 308 broilers(male and female each accounting for 1/2)were selected,randomly divided into the control group and the test group,and fed with the original diet and the revised diet,respectively.There were 10 replicates in each group and 500 broilers in each group for 42 d.The final body weight of broilers in the experimental group was significantly higher than that in the control group in the three feeding stages(P<0.05).The body weight gain,feed weight ratio and unit weight gain cost of broilers in the experimental group were significantly better than those in the control group in the three feeding stages and the whole process(P<0.05).The total evisceration rate of broilers in the test group was 2.1 percentage points higher than that in the control group,and the difference reached a significant level(P<0.05).It was shown that the revised diet plan was better than the original diet plan.
