Productivity of two Phan Rang sheep lines: the second generation
Two experiments were conducted to determine the productivity of two Phan Rang sheep lines (fluff and braided wool sheep lines) at the second selected generation. The first experiment (Exp.1) evaluated the productivity of second generation fluff wool sheep and the second experiment (Exp.2) evaluated the productivity of second generation braided wool sheep. In Exp.1, total of 974 fluff wool lambs borned from 749 ewes resulted from breed 830 female lambs and 83 male lambs at 9 months of age. In Exp.2, total of 486 braised lambs borned from 413 ewes resulted from mating breed 413 female lambs and 41 male lambs at 9 months of age.
The results showed that in the Exp.1, lambs with the white color, fluffy and not sticky hair was 96,2%. The body weight of lambs at birth, 3, 6 and 9 months of age were 2.69; 14.83; 21.46; and 27.34 kg, respectively. The male body weight at all the months was significantly (P<0.001) higher than that of the females. The age at the first lambing was 443 days and the litter size was 1.31 heads. In Exp2, the body weight of lambs at birth, 3, 6 and 9 months was 2.50; 14.1; 20.25; and 24.16 kg respectively. The male body weight at all the months of age was also higher than that of the females (p<0.001). The age at the first lambing was 440 days and the litter size was 1.32 heads age.
