Authors : Menani1 A. A. . Dekhili M. . Khilifi A. .
Abstract
Lamb survival of 327 progeny of Ouled-Djellal ewes was investigated. There was no difference in survival rate between singles (88%), twins (80%) and triplets (88%). The second main effect, sex there was a significant difference between males (81%) and females (89%), showing a difference of 8% (P<0.05). The overall mean lamb survival rate was of 85%. The majority of lamb died (58.8%) during the first week from non-genetic effect. It is suggested that nutritional management and absence of care of the ewe was a fault.
