Sažetak
The objective of this work was to develop a new genotype of cattle using Southern Anatolian Red cows and Simmental semen and to study some of the productive traits of F1 crossbred generation. The animal material consisted of 50 Southern Anatolian Red cows and 80 crossbreds. All the cows calved normally and without any assistance. No serious health problems were observed up to 18 months of age. The average birth masses of the male and female calves were 35.3±0.8 and 32.8±0.6 kg, respectively and the difference was statistically significant (P<0.05). The animals reached 516.4±10.4 and 445.3±5.0 kg, in the above order, live mass (P<0.01) at 18 months of age. Fattening with 10 males was started at a mass of 125 kg and lasted until 550 kg. The dressing percentage of chilled carcass was 59.0% with carcass values of 17.3% bone, 78.9% saleable meat, 23.8% prime cuts and 2.0% pelvic fat. The results indicate that Simmental genotype will contribute to Southern Anatolian Red positively for the development of a new dual-purpose breed of cattle, giving priority to beef production.
