Özet

The present study was carried out to identify the reproductive characteristics, survival rate, growth traits and some body measurements of Bafra (B), Akkaraman (A), Bafra x Akkaraman F-1 (BAF(1)) and Bafra x Akkaraman B-1 (BAB(1)) sheep genotypes. The research was performed at Gozlu State Farm, belonging to the General Directorate of Agricultural Enterprise (TIGEM), during the years of 2014-2016. In the study, lambing rates of BxB, AxA, BxA and BxBAF(1) mating groups were 55.25, 69.97, 67.25 and 64.91%; the lamb production were 92.27, 88.93, 87.54 and 122.81% and the litter sizes were 1.67, 1.27, 1.30 and 1.89, respectively. The survival rates of B, A, BAF(1) and BAB(1) lambs were calculated as 89.89, 94.23, 88.79 and 98.36% in the 90th day, respectively (P<0.05). The least square means of these lambs were 3.65 +/- 0.05, 4.71 +/- 0.07, 4.56 +/- 0.06 and 4.03 +/- 0.10 kg (P<0.001) for birth weight and 23.51 +/- 0.30, 31.39 +/- 0.37, 30.00 +/- 0.35 and 25.16 +/- 0.53 kg (P<0.001) for the 90th day weight (weaning weight), respectively. Body measurements of these genotypes on the 90th day were 56.79 +/- 0.45, 61.75 +/- 0.54, 60.98 +/- 0.59 and 61.73 +/- 0.62 cm (P<0.001) for the withers height; 55.76 +/- 0.32, 55.18 +/- 0.39, 56.91 +/- 0.42 and 57.43 +/- 0.45 cm (P<0.01) for the body length; 63.05 +/- 0.73, 71.88 +/- 0.89, 60.89 +/- 0.96 and 61.92 +/- 1.02 cm (P<0.001) for the chest girth; and 16.63 +/- 0.50, 40.45 +/- 0.62, 28.33 +/- 0.67 and 18.33 +/- 0.70 cm (P<0.001) for the widest tail circumference, respectively. In conclusion, the reproductive performance of the BAF(1) genotype was satisfactory; BAF(1) lambs were partially similar to A lambs, but BAB(1) lambs were partially similar to B lambs in terms of growth characteristics.
