Evaluation of the Relationship Between Body Measurements and Carcass Traits of Finishing Afshari and Zandi Rams

A. Lavvaf, A. Noshari and T. Farahvash    

Abstract: In order to evaluate the relation between body measurements (body length, stator, chest girth, body depth and romp width) with carcass traits (live weight, warm carcass weight, warm carcass efficiency, warm carcass weight without fat-tail and warm carcass without fat-tail efficiency), records from 200 Afshari and Zandi rams collected. Genetic group had effect on the warm carcass efficiency (p<0.01) and Zandi rams had higher efficiency. Chest girth affected by genetic group (p<0.05) which Afshari rams had bigger chest girth. Both genetic groups had high correlations between chest girthxlive weight, romp widthxlive weight, chest girthxwarm carcass weight without fat-tail, live weightxwarm carcass weight without fat-tail, warm carcass weightxwarm carcass weight without fat-tail. Results showed that chest girth was the best index in predicting body weight to 6 months of age at both genetic groups. Live weight at 6 months could be used to predict the warm carcass weight and warm weight without fat-tail. Chest girth and romp width in Afshari and Zandi, respectively were suitable factors for predicting warm carcass weight and warm carcass weight without fat-tail.
