ABSTRACT
In this research, linear regression models were improved for estimation of body weight using various linear body measurements from Sudanese Shugor sheep. Simple regression models were formed when Body weight (Bwt) was dependent variable and heart girth (HG), height at withers (HTW) and height at hip (HTH) as independent variables. The best derived regression prediction equation for estimation of body weight determinated by using beta (β) as the constant based on number of variables used for the equation, mean square error (MSE) and Coefficient of determination (R2). The model including the most appropriate measurements such as heart girth, height at wither and height at hip were the best fitted model (β = -47.54, MSE = 9.39 and R2=0.61) for estimation of body weight in Sudanese Shugor sheep in this study.
