应用超声波技术快速预测羊背膘厚和眼肌面积的研究

Abstract

Abstract: Back fat thickness and eye muscle area were both as important selective traits in mutton sheep breeding. In order to be able to predict them in vivo experiment, three sheep breeds and total 36 were estimated and measured before and after slaughter. The prediction model on back fat thickness,eye muscle area,and carcass weigh after slaughter by ultrasonic measurements in using least-squares procedure were established and the results showed that the prediction model were significant (P<0.05).Therefore,it can be applied in practical.

Key words: sheep; ultrasonic technology; back fat thickness; eye muscle area; carcass trait
