This study was conducted to investigate the effects of genotype, sex and different feeding types on growth performances of turkeys. The study population containing White and Bronze Turkey poults was sheltered at completely closed and controlled compartments during an eight week period regardless of the sex and feeding type. The live weights of the turkeys on the 15th, 30th, 45th and 60th days were determined by fixing with interpolation.

At the end of the eight week period, White and Bronze turkeys were found to reach average live weights of 1711.44 g and 1318.08 g, respectively. Following the differentiation according to sex and feeding type, the average live weights of male-female White turkeys and male-female Bronze turkeys belonging to the intensive group were calculated as 6205.9-4750.0 g and as 5258.0-4112.9 g, respectively, at the end of the study period prior to slaughtering. On the other hand, the average live weights of male-female white turkeys and male-female bronze turkeys belonging to semiintensive group were determined as 5631.8-4577.7 g, and as 5028.9-4133.0 g, respectively. The differences between the sex and feeding type groups in both genotypes were found to be statistically significant (P<0.001). The effects of sex and feednig type on both genotypes were found to be statistically significant (P<0.001). Total feed consumption was determined to be higher in males than females and in intensive group than semi-intensive group in both genotypes (P<0.01, P<0.001).

The present study aimed to investigate the feasibility of intensive turkey breeding which still lacks sufficient attraction, and the results suggest that an integration-like model which is widely applied in broiler production and marketing can also be used in turkey breeding. This may be beneficial as an alternative poultry breeding. It is concluded that breeding of Bronze Turkeys under semi-intensive system and of white turkeys under intensive system might be more appropriate.
