Productivity of two Phan Rang sheep lines: the third genegation
Two experiments were conducted to determine the productivity of two Phan Rang lines at the third selected generation. The first experiment (Exp.1) evaluated the productivity of third generation fluff wool sheep and the second experiment (Exp.2) evaluated the productivity of third generation braided wool sheep. In Exp.1, In Exp.1, total of 440 lambs borned from 336 ewes resulted from breed 373 female lambs and 37 male lambs at 9 months of age. In Exp.2, total of 220 lambs borned from 167 ewes resulted from breed 185 female lambs and 19 male lambs at 9 months of age. In Exp.1, White color, fluffy, not sticky was 100%. The body weight of lams at birth, 3, 6 and 9 months of age were 2.7; 14.42; 20.29; and 26.75 kg, respectively. The body weight of male lambs at every months of age was significultly (P<0.001) higher than that of female lambs. The age at first lambing was 439 days, litter size was 1.32 heads per litter. In Exp.2, the body weight of lams at birth, 3, 6 and 9 months of age were 2.50; 14.38; 20.09; and 25.43 kg respectively. The body weight of male lambs at every months of age was significultly higher than that of female lambs. The age at first lambing was 437.4 days, litter size was 1.33 heads per litter.
