Abstract
A comparative study on the growth performance of three Egyptian sheep breeds raised under an intensive management system was carried out to improve lamb production using10 Rahmani, 8 Ossimi and 23 Barki male and female lambs. Data was analyzed using the general linear model procedure. The results showed that there was an increase in the lamb’s live body weight and a decrease in both lamb’s monthly body daily weight gain and periodic average daily gain toward advanced ages with instability in the rate of monthly growth during certain periods. Barki sheep tended to have the same monthly live body weight compared with Rahmani lambs and higher monthly live body weight compared with Ossimi sheep with better growth rate for the periods from birth to two months, five to six months and nine to ten months of age, compared to both Rahmani and Ossimi lambs. Except for the period from weaning to marketing, Barki lambs tended to have the same average daily gains compared to Rahmani sheep and exceeded the Ossimi sheep. On the other hand, the results showed a significant effect of sex on the growth performance of lambs of the three breeds, where the age of the dam and the birth weight of the lamb had no significant effects. It could be concluded that the intensive management system is a good practice for increasing the meat production of Barki sheep < /span>
