Abstract
This study was conducted by using18 Awassiewes , 2-4 years aged, with average body weight 61.56 kg. The ewes were randomly divided into three groups, six ewes in each group. All ewes received 1.5 kg/ dry matter from the same basal diet consist mainly of barley, wheat bran, soybean meal and wheat straw . The first group was fed on basal ration only ( T1 ) ,while 45g /ewe /day sodium bicarbonate was supplemented to the feed of the second (T2)group and third (T3) group was supplemented with 45g sodium bicarbonate plus 0.5g mixture of Vitamin E and selenium /ewe/day. Results showed that the treatments hadsignificant increase( P < 0.05 ) on milk production of T3(739 g/d) than T1,T2(571and 599 g/d)respectively. No effect on average body weight, lactose, fat and protein percentage in milk. Rumen liquor pH, ammonia and total count of rumen bacteria and protozoa before feeding was not affected, while after 2hr of feeding, pH value of rumen liquor was increased (P < 0.05) in T2 6.65 as compared with T1 5.62 and T3 6.13. Ammonia and microorganism concentration in rumen liquor and blood parameters were not affected by experimental treatments.
Highlights
INTRODUCTIONThere are many ways to improve milk consumption of concentrated feed by animals, production (quantity and quality)providing especially cereals, which contain a high suitable environmental conditions of the percentage of quick fermentation carbohydrate rumen and exploitation of nutrients decrease and the pH of rumenliquor, causing compounds and metabolism in addition to determine the activity of rumen bacteria in health care of the somatic cells of the udder. which especially cellulolytic bacteria and Animals need good feed to produce milk. reduce the proportion of acetate to propionate

Summary
There are many ways to improve milk consumption of concentrated feed by animals, production (quantity and quality)providing especially cereals, which contain a high suitable environmental conditions of the percentage of quick fermentation carbohydrate rumen and exploitation of nutrients decrease and the pH of rumenliquor, causing compounds and metabolism in addition to determine the activity of rumen bacteria in health care of the somatic cells of the udder. which especially cellulolytic bacteria and Animals need good feed to produce milk. reduce the proportion of acetate to propionate. There is a growing need and low fat milk [9], and that the add rates for animal food to produce milk and this may acidity such as sodium bicarbonate and others render the animal in the case of the balance of can havepositive role in improving the negative especially if the production is percentage of milk fat and milk production high[14], may be exposed females after giving [31].This study was designed to find out birth to stress due of milk, especially those theeffect of mixture Vitamin E with selenium with highly productive result of the and sodium bicarbonate on the rumen deterioration of the immune status and low characteristic and their impact on milk concentration antioxidants in the body, leading production and its components in Awassi to increased opportunities for exposure to ewes. Of Vitamin E to improving the immunity of basal diet + 45g /ewe /day sodium bicarbonate animals and reproductive performance. E and addition of Vitamin reduces the number of selenium/ewe/day.Sodium bicarbonate,Vit E somatic cells in milk (Somatic Cell Count) and Selenium added handily to ration before and increase the growth of bacteria analyst feeding animals at morning daily
