摘要
为探讨新疆褐牛青年母牛不同月龄体尺、体重生长发育规律,进一步掌握体尺、体重、主要产肉指标之间的相关关系。本试验采用单因素方差分析(ANOVA)方法对不同月龄新疆褐牛体重体尺数据进行分析,并对各指标之间进行相关性分析。结果表明:不同月龄体尺、体重有不同,其中体重在6至12月之间(22.81 kg/月)增重较明显;体高、体长、胸围和管围均在0至6月龄之间增长较明显。新疆褐牛出生至6月龄之间体尺体重生长发育最快,与其他月龄段有显著差异(P<0.05);体重与体高、体长、胸围、肌肉厚度之间存在呈正极显著相关(P<0.01)。综上,新疆褐牛体重、体尺及肌肉厚度等产肉指标是相互联系、相互影响,初步确定新疆褐牛的体重、胸围和管围在0至12月龄之间生长发育快,因此新疆褐牛育成牛的早期饲养管理是不可忽略的环节,抓好早期饲养管理是新疆褐牛生长发育和增重的根本保证。
In order to explore the growth and development of body size and weight of young cows of Xinjiang brown cattle at different months of age,and to further grasp the correlation between body size,body weight and main meat production indicators.In this experiment,a single factor analysis of variance(ANOVA)method was used to analyze the weight and body size related data of Xinjiang brown cattle at different months of age,and the correlation analysis between various indicators was carried out.The results showed that the body size and weight of cows at different months were different.Among them,the weight gain was more obvious between 6 and 12 months(22.81 kg/month);body height,body length,chest circumference and tube circumference increased significantly between 0 and 6 months.The growth and development of body size and weight of Xinjiang brown cattle from birth to 6 months old was the fastest,which was significantly different from other months old(P<0.05);there was a positive significant correlation between body weight and body height,body length,chest circumference,and muscle thickness(P<0.01).In conclusion,the meat production indicators such as body weight,body size and muscle thickness of Xinjiang brown cattle were interrelated and influenced each other.It was preliminarily determined that the body weight,bust circumference and tube circumference grew fast between 0 to 12 months of age.Therefore,the early feeding management of Xinjiang Brown cattle could not be ignored,it was the fundamental guarantee for the growth and weight gain of Xinjiang brown cattle.
