Abstract: The study was conducted in the animals’ field of the Department of Animal Production / College of Agriculture and Forestry/University of Mosul, to clarify the impact of adding a mixture of enzymes Amylase, Protease and Cellulose with the probiotic in different proportions on milk production and its components in Awassi ewes. The study was carried out by using 12 ewes by using cross over design, the ewes were divided into three groups and fed periodically on the experimental feed at three periods, and each period took up 17 days (15 days’ adaptation period and two days for the collection of milk and blood samples). The ewes in all treatments were fed on standard feed formed of barley, wheat bran, soybeans and wheat straw, with a 1.5 kg/ewe per day of feed, without addition in first treatment (control), or with adding 2g from enzymes mixture and probiotic per ewe per day in the second treatment, while adding 4g of mixture enzymes and probiotic per ewe per day in third treatment. The results showed an improvement in milk production by 10% and 7%, when adding a mixture of enzymes and probiotics in the second and third treatments compared to the control, while the addition was not affected on milk components of protein, fat, lactose and solid non-fat. The results of blood measurements pointed out a significant increase (p≤0.05) in the concentration of the total protein and globulin in second treatment 7.75 and 3.51 g/dl, respectively, compared to the control treatment 6.95 and 2.7 g/100 ml, respectively, while triglycerides decreased significantly (p≤0.05) in second treatment, 38.44 mg/dl as compared to the third treatment 43.91 mg/dl. In general, the addition of the enzymes mixture and probiotic improved the production of milk and blood immune proteins in Awassi ewes.
