| Abstract | ||
| This experiment was conducted using 12 Awassi ewes in early stage of lactation , Ages ranged between 3-4 years with average body weight 49,58kg . Ewes allocated according to body weight and milk production . into three groups each of four with their lambs , and fed on 1,750kg/day of three rations periodically in ( 3×3 ) Latin squar design , each period lasted 17 days . First ration was control (T1) consist mainly of barley , wheat bran and soybean meal , In the second and third rations soybean meal was treated with formaldehy with supplement Urea the third ration to increased its content of rumen degradable protein . Results indicated that the treatment had no significant effect in milk production which were 620-638 g/day or in fat corrected milk 4% fat 748-773 g/day . Also the differences were not significant in milk fat 5.04-5.53 % , protein 5.76-6.18 % , Lactose 4.50-4.53 % and milk Urea 32.00-37.04 mg/dl . Results showed significantly increased (p≤0.05) in blood glucose in T2 (114.21) mg/dl as compared T1 and T3 (108.71, 99.46) mg/dl, and in urea concentration in T3 as (69.44) mg/dl compared T1,T2 (68.48 , 57.17) mg/dl . while the other measurement un affected significantly by treatments. | ||
