This study was performed to determine meat, bone and fat percentages in different parts of carcasses of Gökçeada Goat kids grown in different production systems. Totally, 27 male kids in three different groups were used as material. Group I-Suckling Kids (n:7): Grower concentrate and Alfalfa hay were given to the goat kids in addition to their mother’s milk until 80-90 days of age; Group II-Intensive System Kids (n:10): Kids stayed with their mothers whole day during 7 days after birth and then mothers were separated from their kids in the mornings. After the evening milking the dams and kids were put together until morning. The kids were weaned when they reached the average age of 47 days. Starting from the second weeks of age, the kids were fed ad libitum with Alfalfa hay and pelleted concentrated feed. Group III- Extensive System Kids (n:10): Kids stayed with their mothers on Gökçeada Island until 4 months of age. In the suckling period the dams were not milked and the kids grazed freely in the pasture and suckled their mother. Group I kids were slaughtered at approximately 80-90 days of age, other kids from Group II and Group III slaughtered at approximately 4 months of age. Carcass compositions were determined by dissection. Each carcass part was dissected into muscle, bone, subcutaneous fat, intermuscular fat and other tissues. Other tissues included blood vessels, tendons, nerves and lymph nodes. When goat kids carcasses compared in terms of muscle rate; the differences between groups were not found significant (P>0.05) for neck, shoulder, leg, flank and tail carcass parts. However, Group I (P<0.001) showed higher values for loin and rib. Bone rates were found significant for all carcass parts in all production systems. Bone rates showed lowest values in group III among other carcass parts. It was determined that Group III showed highest value in terms of total fat rate of carcass parts (P<0.01). In conclusion, when different carcass components evaluated, it was found that suckling goat kids and intensive reared goat kids produced less fatty carcass. On the other hand suckling goat kids showed higher values in terms of rib and loin meat percentage.
