| Sumario: | Genetic parameters were estimated for birth-, 42-day, and 100-day (weaning) weight in the Dorper flock of the Glen Agricultural Institute in South Africa. Direct habitability estimates of 0.11, 0.28 and 0.20 and maternal habitability estimates of 0.10, 0.10 and 0.10 were obtained for body weight at birth, 42 and 100 days, respectively. The corresponding genetic correlation estimates among the traits were of moderate to high magnitude and positive. It is concluded that the traits can be improved by selection with no serious antagonisms among traits studied.
