Purpose: This study is aimed at comparing the nutritional performance, cutting and carcass characteristics of the Bafra, Akkaraman and Bafra × Akkaraman F1 shells in different cutting weights. Tools and Methods: In the study, an animal material of about 20 kg of living weight, 48 heads of men were used, including 16 heads of Bafra (B), Akkaraman (A) and Bafra × Akkaraman F1 (BAF1). The cows are fed with food and ad libitum and 300 g of dried corn per animal per day. The post-cutting wrinkles are divided into 7 pieces as but, arms, back, back, neck, floor and others, and the proportions of meat, fat, bones and waste in each piece are determined by physical disection. The findings: The highest daily living weight increase (P<0,001) in the Akkaraman race was found, the lowest rate of use of food (P<0,05) was found. The BAF1 genotype with a cut weight of 34 kg has a significant advantage (P<0,05) and the cut weight of 42 kg has eliminated the differences between the groups. The BAF1 genotype (P<0,05) with a cut weight of 34 kg in terms of carcast meat weight; the Bafra and the BAF1 groups with a cut weight of 42 kg have received the highest values (P<0,01). In all cutting weights, the percentage of carcaste oil is significantly higher compared to Accaramans in Bafra and BAF1 groups (P<0,05).  Recommendation: In terms of iron performance, the Akkaraman shells have shown significant superiority over the Bafra and BAF1 groups. The high body weight and the high body weight in the BAF1 group indicates that the melez genotype can give positive results in nutrition; therefore, it is appropriate to continue the melezing of Bafra × Akkaraman.
