应用超声波技术快速预测羊背膘厚和眼肌面积的研究

在肉羊育种中，背膘厚和眼肌面积是重要的选择性状，为了能够对其进行活体预测，试验通过对3个羊品种（36头）屠宰前后的背膘厚和眼肌面积的估测和实测数据运用最小二乘法建立了用超声波活体测量技术预测宰后背膘厚、眼肌面积和屠宰重的预测模型，结果显示预测模型均达到显著水平（P＜0.05）。因此，可以在育种实践中应用。

Rapid Prediction of Sheep Back Fat Thickness and Eye Muscle Area in Using Ultrasonic Technology

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 ap...
