| Abstract | ||
| This study was conducted in Al-Rashidiya animal breeding station. Using 24 Awassi ewes after weaning. (3-5 yrs. old) with average body weight of 56.96± 1.49 kg. The ewes were divided randomly according to their weight and milk production into four groups. The first (T1) and second (T2) treatments were fed on rations consist of 35% barley, contained 10 and 13 g degradable protein/MJ metabolizable energy. While barley grain raised to 62% in the rations of third (T3) and fourth (T4) treatments with preservation the same level of degradable protein 10 and 13 g/ MJ respectively. Ewes in the treatments fed with 1.750 kg / day. Results indicated that milk yield decreased with increased degradable protein levels significantly (p<0.05) in T4 186 g/ day as compared T1 and T3 391 and 408 g/ day. Percentages of milk protein, lactose and solid not fat was significantly (p<0.05) decreased in T4 as compared with other treatments, milk urea was significantly (p<0.05) higher in high barley rations (T3 and T4) 11.08 and 15.23 mg/dl as compared low barley content in (T1 and T2) 8.86 and 8.36 mg/dl respectively, also was decreased (p<0.05) in T4 compared T3. Blood triglyceride concentration was significant (p<0.05) increased in T4 compared other treatments 8.71, 7.06, 11.25 and 8.17 mg/dl. While albumin concentration was significant (p<0.05) increased in T4 3.55 mg/ dl compared T1 3.18 mg/dl. | ||
