摘　　要：试验旨在探究不同杂交新疆褐牛在伊犁地区规模养殖场的生长性能,分析和比较了12、24月龄杂交美×新褐牛F1(MHF1)、杂交美×新褐牛F2(MHF2)、杂交德×新褐牛F1(DHF1)及新疆褐牛(XH)各体尺指标的差异。结果显示,12月龄时,DHF1体高显著高于XH(P<0.05),体斜长、体重显著高于其余3组(P<0.05),胸围显著高于XH、MHF1;MHF1、MHF2、DHF1管围均显著高于XH(P<0.05)。24月龄时,MHF1、MHF2、DHF1的体高、体斜长、胸围、体重均显著高于XH(P<0.05),MHF2的体高、体斜长、胸围、体重均显著高于DHF1及XH(P<0.05)。研究表明,美国瑞士褐牛与德国褐牛与新疆褐牛杂交可提高新疆褐牛生长发育水平,12月龄的德系褐牛杂交后代生长发育情况优于美系褐牛,但在24月龄美系杂交二代褐牛生长发育情况均显著高于德系杂交褐牛。The purpose of the experiment was to investigate the growth performance of different hybrid Xinjiang brown cattle in large-scale breeding farms in Yili area,and to analyze and compare the differences of body size indexes of hybrid American×New Brown cattle F1(MHF1),hybrid American×New Brown cattle F2(MHF2),hybrid German×New Brown cattle F1(DHF1)and Xinjiang Brown cattle(XH)at 12 and 24 months of age.The results showed that at 12 months of age,body height of DHF1 was significantly higher than that of XH(P<0.05),body oblique length and body weight were significantly higher than those of the other three groups(P<0.05),and chest circumference was significantly higher than that of XH and MHF1.The tube circumference of MHF1,MHF2 and DHF1 was significantly higher than that of XH(P<0.05).At 24 months of age,the body height,body oblique length,chest circumference and body weight of MHF1,MHF2 and DHF1 were significantly higher than those of XH(P<0.05),while the body height,body oblique length,chest circumference and body weight of MHF2 were significantly higher than those of DHF1 and XH(P<0.05).The study indicates that the crossing of Swiss brown cattle with German brown cattle and Xinjiang Brown cattle could improve the growth and development level of Xinjiang brown cattle.The growth and development of the offspring of German brown cattle at 12 months of age was better than that of American brown cattle,but the growth and development of the second generation of American brown cattle at 24 months of age were significantly higher than that of German brown cattle.
