| 摘 要： | 研究了整粒玉米对绵羊日增重、饲料转化率和养分消化率等的影响。选择体重约24kg的杂交羔羊20只，随机分为2组。对照组饲喂基础日粮，试验组每以等量整粒玉米替代基础日粮中的玉米。结果表明：平均日增重试验组比对照组高32．73g，提高20．69％（P〈0．05），饲料转化效率提高14．52％。干物质和有机物质的消化率试验组明显高于对照组，分别比对照组提高8．22和5．92个百分点。

| Abstract: | The experiment studied the effect of the corn grain on body weight gain of sheep,feed efficiency and digestibility.20 lambs with an initial weight of 24kg were randomly divided into 2 groups.The control group was fed with the basal diets and the trial group was fed with the corn grain of the same quantity instead of corn in the basal diets.The results showed that the average body weight gain in trial group was 32.73g higher than the control group,increased by 20.69%(P<0.05),the feed efficiency increased by14.52%.The digestibility of dry matter and organic matter in trial group were obviously higher than the control group,respectively 8.22 and 5.92 percents higher. |
