Abstract

The experiment was conducted in the field of animal production of the research ruminants – Office of Research - Ministry of Agriculture in the region of Akrokov 25 km northwest of Baghdad for the period from 16/3/2016 to 4/6/2016, and the objective of the experiment was the effect of addition of different levels of fibro lytic enzymes .The concentrate diet on production and physiological performance lactating Ewes Awassi, In the first experiment, 26 pregnant sheep were used In the late stage and before birth and at the age of 3-5 years, With a weight of 67 kg, The first experiment lasted 42 days preceded by 10 days introductory period The ewes were divided into four groups, each with 6 ewes, of which 15 were born, Treatment control 3 ewes, first treatment 5 ewes, second treatment 4 ewes, third treatment 3 ewes, The trial period was divided into three successive periods from birth every 14 days, Control group without enzyme and treatment of the first, second and third enzyme concentration 1,3,5 kg t-1, respectively. The preliminary period is 10 days ahead, the results showed that: The addition of fibrolytic enzymes to the concentrate diet of the fodder resulted in a significant increase P<0.01 in the first treatment and in the second period and the general average and a significant increase of P<0.05 in the third period in milk production.
The chemical composition of the milk was significantly higher P<0.01, the percentage of milk fat for the first and second treatment compared to the control treatment, and significantly higher P<0.05. All treatments were treated with milk protein control in the second period, and the percentage of milk lactose was significantly reduced P<0.01 for all the treatments compared to the control treatment. The results showed a significant increase P<0.05 in the overall rate of the second treatment compared to the control treatment of the percentage of Ash in milk, The first period showed a significant increase P<0.05 for Ash in milk for the second treatment compared to control, In the second period, the second and third treatment was significantly higher P<0.05compared with the control treatment.
