Study on Body Weight Growth Curve in Xinjiang Brown Cattle
摘要
Abstract
The experiment was designed to investigate growth and development pattern and reveal the correlation of each traits of Xinjiang Brow n cattle according to analysis body index data .2 794 Xinjiang Brown bulls were selected to measure body index and draw the growth curve of body weight during year 2010 to 2015 in Yili Zhaosu region .The body index was composed by body weight ,body height ,body length ,chest circumference and canon circumference .All measured data were analyzed and validated underwent correlation and regression analysis .The results showed that body length of Xinjiang Brown bulls were grow fastely at the age 14 to 15 months ;Body weight was extremely significantly positive correlated with other four measured body index (P<0 .01) .Of them ,the correlation coefficient with chest circumference was the highest (r=0 .796) , and the lowest was with body length (r=0 .163) .The body weight regression estimate formula of Xinjiang Brown bulls was Y= -564 .607-0 .174X1 + 2 .441X2 +3 .497X3 -1 .086X4 ,and the vali‐dation result implied this formula was statistical significance .Our work offers a good data basic for genetics selection and breeding of Xinjiang Brow n cattle .关键词
