Effect of Substitution Gradually Percentages of Chemical and Microbial Treated Corn Cobs with Barley on some Biochemical Values of Awassi Ewes

Abstract

The Study was conducted on (51) Awassi ewes (1.5- 3 years old). The ewes divided into three groups, each group with 17 ewes. The Animals were fed different levels of treated corn cobs (0-5-10%).Blood samples were collected monthly by jugular vein puncture. The plasma was drawn off by Centrifugation to determine the enzymatic activity of the enzymes trans amino (Alanine Transaminases AL.T and Aspartate Transaminase AS.T) and lactate dehydrogenase (L.DH.) in ewes fed treated corn cobs.The measurement of enzymatic activity showed no significant difference in AL.T activity in different groups.Significant decrease (p<0.05) in level of AS.T. enzyme at fourth month of the experiment period in the third group compared to that of first and second groups.Significant increase (p<0.05) in level of L.D.H. enzyme at third month in the third group compared to that of first and second groups.It was concluded that feeding the Awassi ewes on the concentrate feed of corn cobs at a level of(10%) without undesirable effects
