Some production characteristics of Bafra, Akkaraman, Bafra × Akkaraman F1 and B1 sheep genotypes

Abstract

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 × Akkaraman F1 (BAF1) and Bafra × Akkaraman B1 (BAB1) sheep genotypes. The research was performed at Gözlü State Farm, belonging to the General Directorate of Agricultural Enterprise (TİGEM), during the years of 2014-2016. In the study, lambing rates of B×B, A×A, B×A and B×BAF1 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, BAF1 and BAB1 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 BAF1 genotype was satisfactory; BAF1 lambs were partially similar to A lambs, but BAB1 lambs were partially similar to B lambs in terms of growth characteristics.
