摘要: 目的】研究新疆褐牛(肉用类型)生产性能测定与选育,为培育新疆褐牛肉用新类型提供依据。【方法】在新疆褐牛核心育种场对290头新疆褐牛肉用新类型进行体尺测定和B超检测。【结果】5岁以上新疆褐牛体重、体高、胸围、管围、胸深、胸宽、腰角宽、髋宽均显著高于2014年测定结果(P<0.05);4岁新疆褐牛的体重、体高、胸围、管围、胸深、胸宽、腰角宽、尻长、髋宽均显著高于2014年(P<0.05);3岁新疆褐牛体重、体高显著高于2014年(P<0.05);24月龄新疆褐牛体重、体高、体斜长、胸围、管围、胸深、后腿围、尻长均显著高于2014年(P<0.05);18月龄新疆褐牛体斜长、管围显著高于2014年(P<0.05);12月龄及6月龄体尺鉴定指标均有高于2014年的趋势,差异不显著(P>0.05)。2019年5岁以上、4岁、3岁新疆褐牛眼肌高度、眼肌面积、肌间脂肪含量均显著高于2014年测定值(P<0.05);2019年24月龄、18月龄、12月龄新疆褐牛眼肌高度和眼肌面积均显著高于2014年的测定值(P<0.05)。【结论】2019年新疆褐牛各个年龄阶段的体尺测定指标与2014年测定的记录相比均有所提高。

Abstract: Objective】 The project aims to breed new types of Xinjiang brown cattle in Xinjiang in order to enrich the internal structure of varieties. 【Methods】 A total of 290 new types of brown beef in Xinjiang were determined by body measurements and B - ultrasound at the core breeding farm. 【Results】 The body weight, body height, chest circumference, tube circumference, chest depth, chest width, waist angle width and hip width of Xinjiang brown cattle over 5 years old were significantly higher than the results measured in 2014 (P<0.05). The body weight, body height, chest circumference, tube circumference, chest depth, chest width, waist angle width, bottom length and hip width of 4-year-old xinjiang brown cattle were all significantly higher than that of 2014 (P<0.05). The body weight and height of 3-year-old Xinjiang brown cattle were significantly higher than that of 2014 (P<0.05). The body weight, height, oblique length, chest circumference, tube circumference, chest depth, hind leg circumference and bottom length of Xinjiang brown cattle aged 24 months were all significantly higher than that of 2014 (P<0.05). The body length and tube circumference of 18 months old brown cattle in xinjiang were significantly higher than that in 2014 (P<0.05).The body size identification indexes at 12 months and 6 months were higher than 2014,the difference is not significant after statistical analysis.(P>0.05)the results of B ultrasonic: the height, eye muscle area and intermuscular fat content of brown cattle in Xinjiang aged 5 years and above, 4 years and 3 years in 2019 were significantly higher than those measured in 2014(P<0.05).The height and area of the eye muscle of Xinjiang brown bull at 24 months, 18 months and 12 months in 2019 were significantly higher than those measured in 2014 (P<0.05). 【Conclusion】 The results showed that the body measurements of Xinjiang brown cattle at all ages in 2019 were improved compared with the records measured in 2014.
