摘要:

为研究安格斯牛各体尺指标及体重间的相关关系,掌握其生长发育规律,试验采集了新疆天山某安格斯牛场出生于2012-2016年的安格斯牛生长发育记录,共649条,其中主要包括体重及体尺指标,应用SPSS 16.0软件分析安格斯牛主要体尺指标及体重的相关性。结果发现:安格斯牛体尺指标及体重均随着月龄的增加逐步增大;14月龄之前各体尺指标增长速度较快,14月龄以后增长速度的缓;腹围和胸围增长速度高于其他指标。安格斯公牛的体长指数、体躯指数、胸围指数和管围指数平均分别为111.99%、129.79%、145.26%和16.71%;母牛体长指数、体躯指数、胸围指数和管围指数平均分别为112.15%、132.01%、147.86%和16.95%。安格斯牛体重与体高、体长、胸围、腹围和管围的相关性均达到极显著水平(P<0.01);各体尺指标两两均呈极显著正相关(P<0.01),其中,胸围与腹围的相关性最高,公、母牛相关系数分别为0.948、0.939;腹围与管围之间的相关性最低,相关系数分别为0.797和0.851。本试验结果可为明确安格斯牛选育方向,开展其遗传育种、品种资源开发利用提供基础数据。

Abstract:

To study the correlation relationship between body size indexes and body weight of Angus cattle and explore the growth regulation,649 growth development records were collected of Angus cattle born from 2012 to 2016 of a Angus ranch in Tianshan of Xinjiang,including body size indexes and body weight records.The SPSS 16.0 software was used to measure correlation relationship between body size indexes and body weight.The results showed that the body size indexes and body weight of Angus cattle gradually increased with the increase of age;The growth rate of each body size indexes was fast before 14 months of age,and then slow down;The growth rate of abdominal circumference and chest circumference were higher than other indexes.The average body length index,body index,chest circumference index and abdominal circumference index of Angus bull were 111.99%,129.79%,145.26% and 16.71%,respectively;And that of Angus cow were 112.15%,132.01%,147.86% and 16.95%,respectively.The correlation relationship between body weight and body height,body length,chest circumference,abdominal circumference and tube circumference were all extremely significant (P<0.01),and there was an extremely significant positive correlation between each two of body size indexes (P<0.01).The correlation coefficient between chest circumference and abdominal circumference was highest,which were 0.948 and 0.939 of Angus bull and cow,respectively.And the correlation coefficient between the abdominal circumference and tube circumference was the lowest which were 0.797 and 0.851 of Angus bull and cow.The results of study could provide data to clear the direction genetic breeding,develop and utilize of germplasm resources of Angus cattle.
