Five dietary treatments in three trails were conducted with Barki sheep as follows: 60% Concentrate feed mixture (CFM) and 20% Ammoniated wheat straw ( AWS) as basic diet with 20% Cassava (C) in T1, 20% Prosopis juliflora (P) in T2, 20% Acacia Saligna (A) in T3, 10% C + 10% A in T4 and 10% C + 10% P in T5. In Trial 1, Fifteen Barki rams (43± 1.85 kg) divided into equally five treatment groups to evaluate the effect of condensed tannin sources on apparent nutrients digestibility. The results indicated that the rams fed with T3 (20 % A. Saligna) at a maximum level of tannin (8.33 g /Kg DM) had a lower DMI (9.72 %) than the comparable group (T1) (P 0.05) of DM, OM, CP, EE and CF than that on T1 diet by 3.90, 3.57, 1.87, 3.16 and 1.04%, respectively. Rumen ammonia concentrations were decreased with increasing of CT content in experimental diets (T3, T4, T1, T5 and T2, respectively).In Trial 2, Twenty five healthy Barki ewes at late pregnancy, weighing 41±2.29 kg at 3-5 years of age were randomly allocated into five dietary treatments to determine the milk yield and composition and some blood components changes due to tannin sources and productive performance of their offesprings. There was a significant increase (P |
