摘要
为探讨新疆地区西门塔尔犊牛的生长发育规律,本研究对2011—2016年新疆呼图壁种牛场0~6月龄新疆地区西门塔尔犊牛的体重、体尺进行分析。结果表明:新疆地区西门塔尔犊牛体重增重规律与其他品种相似,体尺累积生长平缓,同时西门塔尔牛具有早期发育快的特点;绝对生长曲线总体呈上升趋势,而相对生长曲线呈下降趋势;公犊牛6月龄体重与体高、体斜长、腿围、管围存在极显著正相关(P<0.01),体重与体高的相关系数最高,为0.62;母犊牛6月龄体重与体高、体斜长、胸围、腿围、管围存在极显著正相关(P<0.01),其中体重与胸围的相关系数最高,为0.81;表明性别是影响体重与体尺相关性的重要因素。新疆地区西门塔尔牛分为乳肉兼用和肉乳兼用型,其犊牛的生长发育对后期牛的生产性能有重要影响,因此要注重犊牛时期的饲喂。
In order to investigate the growth and development of Simmental in Xinjiang, the stucly analyzed the body weight and body size data of Simmental from 0 to 6 months old in Xinjiang Hutubi cattle farm from 2011 to 2016. The results showed that the law of Simmental weight growth was similar to that of other breeds, and the cumulative growth of body size was gentle; In addition, Simmental had the characteristics of early development, the absolute growth curve showed an upward trend, while the relative growth showed downtrend. The correlation analysis between body weight and body size in the growth and development stage of Simmental showed that there was a signifi cant positive correlation between body weight and body height, body length, leg circumference and tube circumference of male calves（P0.01）. The correlation coeffi cient between body weight and body height was the highest, which was 0.62. There was a signifi cant positive correlation between body weight, body height, body length, chest circumference, leg circumference and tube circumference of female calves（P0.01）, and the correlation coeffi cient between body weight and chest circumference. The highest is 0.81. It shows that gender is an important factor affecting the correlation between body weight and body size. The Simmental cattle in Xinjiang is divided into both milk and meat and milk and milk. The growth and development of the yak has an important impact on the performance of the later cattle. Therefore, it is necessary to pay attention to the feeding during the yak period.
