中文摘要：

本次试验旨在判断饲喂整粒玉米是否影响绵羊育肥性能.通过2014 年3 月20 日至5 月30 日对新疆兵团第九师164 团育肥羊场100 只德国美利奴与哈萨克羊的杂交后代的育肥试验,结果表明,试验组羊只平均日增重（246.5±28.9） g、屠宰率（47.89±1.22）%,对照组羊只平均日增重（209.3±25.4） g、屠宰率（47.78±1.06）%,两组间日增重差异显著（P 〈0.05）、屠宰率差异不显著（P 〉0.05）.因此在绵羊育肥中可用整粒玉米代替粉碎玉米,即可提高绵羊育肥的日增重,同时在-定程度上可节省饲料粉碎机械的磨损,减轻工人的劳动强度,减少育肥成本,提高绵羊育肥的经济效益.

英文摘要：

This test is to determine whether the fed corn grain effect of sheep fattening performance.From March 20, 2014 to May 30th to the Xinjiang infantry regiment of the NO.9 division 164 regi.ment fattening sheep field hybrids of 100 German Merino and Kazakh sheep fattening test, resultsshow that the experimental group of sheep, the average daily gain of 246.5 ＋ 28.9g, slaughter rate of47.89 ＋ 1.22%, the control group of sheep average daily weight gain was 209.3 ＋ 25.4g, slaughterrate of 47.78 ＋ 1.06%, two groups of Plasmodium vivax gain significant difference （P〈0.05）, slaughterrate did not show significant difference （P〉0.05）. Therefore, in the sheep fattening in available wholecorn instead of crushed corn, can improve sheep fattening daily gain, also to a certain extent, cansave feed crushing machine wear and tear, reduce the labor intensity of workers, reduce the cost ofsheep fattening fattening, improve economic benefits.
