The factors tested are : the flock of sheep, sex of lambs, mode of birth, month and season of birth. Statistical analyses show that the flock of sheep and mode of birth had a significant effect (p<0.001) on all variables. The weight of lambs are : 3.78kg at birth, 9.14kg zt 1 month, 12.89 at the second month, 15.99 at 3rd month and 20.13 at the 4th months.
