摘　　要：旨在探究澳洲白羊与杜湖羊三元杂交F1代(澳杜湖)公羔在育肥期的生长发育与饲料效率之间的关系。以杜泊羊与湖羊杂交一代为母本,澳洲白羊为父本进行杂交,选取99只澳杜湖公羔(80~180日龄)进行育肥期生长发育性状与饲料效率性状的测定。结果:澳杜湖公羔80~180日龄,体重呈递增态势;经统计分析发现,澳杜湖公羔不同日龄阶段体重与体尺指标整体呈显著正相关(P<0.05),澳杜湖公羔平均日增重为(0.30±0.03)kg,平均日采食量为(1.91±0.16)kg,剩余采食量为(0.00±0.14)kg,饲料转化率为5.41±0.67。研究表明,澳杜湖公羔在120~180日龄为增长高峰期,体重与体尺指标呈显著正相关且与胸围的相关系数最高,剩余采食量与饲料效率性状相关,与生长性状不相关,而饲料转化率与生长性状和饲料效率性状显著相关。The aim of this study was to explore the relationship between growth and development and feed efficiency of Australian white sheep and Duhu sheep ternary hybrid F1 generation(AuDuhu) male lamb in the fattening period.Taking the first generation of Dorper sheep and Hu sheep as the female parent and Australian white sheep as the male parent for hybridization,99 AuDuhu male lambs(80-180 days old) were selected to determine the growth and development traits and feed efficiency traits during the fattening.The results were as follows:The body weight of the AuDuhu male lambs showed an increasing trend from 80 to 180 days of age.The statistical analysis showed that there was a significant positive correlation between the body weight and the body size index at different days of age in the AuDuhu male lambs(P<0.05).The daily gain of the AuDuhu male lambs was(0.30±0.03)kg,their daily feed intake was(1.91±0.16)kg,their residual feed intake was(0.00±0.14)kg,and their feed conversion rate was 5.41±0.67.These results showed that the growth peak of the AuDuhu male lambs was at 120-180 days of age.There was a significant positive correlation between their body weight and body size index,and the correlation coefficient between their body weight and chest circumference was the highest.The remaining feed intake was related to the feed efficiency traits but not to the growth traits,while the feed conversion rate was significantly correlated with the growth traits and feed efficiency traits.
