This study was conducted in Ruminants Researches Station /Ministry of Agriculture. Study targeted some parameters of the live weight at slaughter and some non- carcass characteristics in 10 months aged Male goats. The characteristics were studied for 45 Cyprian , 25 Iraqi Local , 18 (Croosbred1) and 5 (Crossbred2) male goats which slaughtered and measured the weights of head, legs, pelt, heart, liver ,lungs and trachea ,spleen, kidneys and testes. The results of the non-carcass components for the different genetic groups (breeds) indicated that percentage of head , pelt, heart and (lungs &trachea %) of live weight at slaughter (LWS%) did not affected with breed , while legs%, was affected significantly (P≤0.01). The pelt and legs Empty Body Weight (EBW%) generated the same results of breed effect in LWS% . Breed effect was significant (P≤ 0.05) as effect on liver % (% of LWS) and lungs & trachea ( as % EBW) . Crossbred 2 generated the higher value significantly (P≤0.01) in the percentage of spleen from LWS. Effect of coat color was significant in some traits and non in others. Results indicated to possibility of some regression equations to used for predict the studied traits from live weight at slaughter.
