| Abstract | ||
| Twenty seven Awassi ewes at different ages (2, 3 and 4 years) with their single lambs at lambing were assigned randomly into three groups. After lambing they were fed on three rations different in protein level (10.68, 12.52, and 14.68%), weekly and total milk yield and chemical composition were recorded during the experimental period (12 weeks). The result indicates that weekly milk yield was increased significantly (P≤ 0.01 ) as protein level in ration was increased, while age of dam and sex of lamb had no significant effect on weekly and total milk yield. Also the results recorded that the percentages of fat and total solid were decreased significantly(P≤ 0.01 ), while the percentages of protein and total solid not fat were increased significantly (P≤ 0.01 ) as protein level in ration was increased, also the age of dam had highly significant effect on milk chemical composition, while sex of lamb had no significant effect on milk chemical composition. | ||
