Abstract

The aim of this study is the prediction for some carcass traits and body measurements of the birth weight and slaughter weight on 32 Awassi sheep. This investigate was conducted at the Sheep farm Department of Animal Science/ College of Agriculture – Baghdad University. The statistical analysis system (SAS) was used to analysis of data.
It became clear that regression of carcass length on birth weight was highly significant (P<0.01), the coefficient was 0.527cm kg, the regression of chest circumference was significant (P<0.05) on birth weight, the coefficients was 0.887 cm kg with limit coefficient (R2 (0.69 cmkg.
The regression of carcass weight, body length, body height and leg length was not significant on birth weight. Results shows that the regression of hot carcass weight, carcass length, body length and height on front of shoulder blade , chest circumference and thigh length on live body weight at slaughtering was highly significant and its coefficients were 0.055 kgkg , 4.092 cmkg, 5.778 cmkg , 7.229 cmkg, 4.371cmkg and 3.022 respectively, with limit coefficients were 0.77, 0.89, 0.91, 0.68, 0.73 and 0.45 respectively, the highly regression of body length on body weight at slaughter ( 0.91) is reflex that body length explained 91% from weight at slaughter and this equivalence is consider the most strict from all used relations of prediction purpose. Results shows there is a positive relation factor and significant (P<0.01) between birth weight whoever carcass length and chest circumference, it was 0.31 and 0.37 respectively, results show also presence positive relation with highly significant between animal weight at slaughter and most of studied characters.
