Analysis of Growth and Development Performance of Type Breeding Groups for Brown Beef in Xinjiang
摘要
Abstract
To study the growth and development performance of Xinjiang brown beef breeding population at different stages,this study tracked and measured the body size and weight traits of the population at birth,6,12,18,and 24 months of age,and used ultrasound scanners to measure backfat thickness,eye muscle area,and intermuscular fat.The results showed that with the increase of age,the body size and weight indicators of cattle showed an increasing trend,and the increase rate was faster in the 6～12 month age stage.The average values of chest circumference index,tube circumference index,body length index,and body mass index of cattle were 131.50%,14.52%,116.90%,and 112.45%,respectively.At the same time,as the age increases,the backfat thickness,eye muscle area,and intermuscular fat value also show an upward trend.At 24 months of age,the eye muscle area reaches 51.22 cm2 and the intermuscular fat reaches 4.22% .The planned selection and breeding of Xinjiang brown cattle have shown significant advantages in later growth and development,with significant results in body size and weight selection.From the meat quality indicators,it can be seen that the meat performance is good.关键词
