中文摘要:

      [目的]旨在相同饲养条件下比较云南不同杂交组合肉牛的短期育肥性能。[方法]在楚雄州大姚齐和牧业有限公司选择年龄为14（±2）月龄的西门塔尔、短角牛、安格斯牛、云岭牛与本地牛的杂交F1代公牛及云岭牛公牛各6头，自由采食相同全混日粮(30%鲜啤酒糟、35%精料补充料、20%蚕豆糠、15%稻草)，在相同饲养管理条件下开展100d（其中预饲期7d，正试期93d）育肥试验，[结论]云岭牛、云岭杂、安本杂、短本杂和西本杂全程日增重(kg)分别为1.194±0.063、1.312±0.094、1.014±0.0731、1.05±0.052和1.314±0.06kg,西本杂与云岭杂两组差异不显著(P>0.05)，但两组增重显著高于安本杂（P<0.05），但与云岭杂、短本杂无显著差异(P>0.05)，云岭牛、安本杂和短本杂全程育肥期日增重也无显著差异（P>0.05）料重比分别为 7.81、7.12、9.13、8.49 、7.56 云岭杂最低。

英文摘要:

      [Objective] to compare the short-term fattening performance of Different Crossbred Beef Cattle in Yunnan under the same feeding conditions. [method]In Chuxiong Dayao Qihe Animal Husbandry Co., Ltd.,2 groups of bulls were selected, 6 F1 generation of hybrid bulls of Simmen-tal, Shorthorn, Angus, Yun-ling Cattle crossed bred with Yunnan Cattle, 6 bulls of Yunnan Cattle, at the age of 14 (± 2) months were randomly fed the same total mixed diet (30% fresh brewer''s grains, 35% concentrate supplement, 20% broad bean bran, 15% rice straw) for 100 days (the pre-feeding period was 7 days and the experimental period was 93 days) under the same feeding and management conditions. [Conclusion]the daily weight gain (kg) of Yun-ling Cattle, Angus×Yunnan Cattle, Shorthorn×Yunnan Cattle and Simmen-tal×Yunnan Cattle was 1.194 ± 0.063, 1.312 ± 0.094, 1.014 ± 0.073, 1.105 ± 0.052 and 1.314 ± 0.06 kg, respectively. There was no significant difference between Yun-ling×Yunnan Cattle and Simmen-tal×Yunnan Cattle (P > 0.05), but the weight gain of two groups was significantly higher than that of Angus×Yunnan Cattle（P<0.05）; However, there was no significant difference between them (P > 0.05), and the daily weight gain difference during the whole growing state of Yun-ling cattle, Angus×Yunnan Cattle and Shorthorn×Yunnan Cattle was not significant (P > 0.05). Feed conversion ratio was 7.81, 7.12, 9.13, 8.49 and 7.56, respectively; among which feed conversion ratio of Yun-ling Cattles was lowest.
