在羊肉生产加工的屠宰线上,为了较快地预测胴体净肉质量和净肉率,并按照不同产肉性能对肉羊胴体进行等级划分,以建立科学合理的优质优价收购体系,本实验选取30头4～8月龄巴美肉羊,对其进行屠宰、冷却、分割,并分别测定其宰前羊体活质量（X1）、热胴体质量（X2）、眼肌面积（X3）、背肉厚度（X4）等指标。将数据采用SPSS 16.0软件进行相关分析和线性回归,最终得到以X1、X2和X3三因子共同预测净肉质量（Y1）的线性方程Y1=-1.113＋1.088X2-0.141X1-0.004X3（R2=0.996）和预测净肉率（Y2）的线性方程Y2=31.187＋2.362X2-1.090X1＋0.068X3（R2=0.920）,结果表明这两个方程均可在实际生产中用于巴美肉羊净肉质量和净肉率的预测。

This study was conducted to establish mathematical models for quick prediction of retail product weight and percentage on lamb slaughtering line with the aim of providing references for lamb carcass grading for high-quality favorable-price purchase. Thirty Bamei lambs aged 4--8 months were selected for slaughtering, chilling and cutting. Pre-slaughter body weight （X1）, warm carcass weight （X2）, loin eye area （X3） and back meat thickness （X4） were determined. Correlation analysis and linear regression analysis were carried out with SPSS 16.0 software. A linear equation for retail product weight （Y1） or retail product percentage （Y2） as a function of pre-slaughter body weight （X1）, warm carcass weight （X2）, loin eye area （X3） was obtained as Y1= - 1.113 ＋ 1.088X2 - 0.141X1 - 0.004X3（R^2 = 0.996） and Y2 = 31.187 ＋ 2.362X2 -- 1.090X1 ＋ 0.068X3（R^2= 0.920）, respectively. It was found that both equations could be used to predict retail product weight and percentage in Bamei lamb.
