Abstract
In digestibility trial twenty four yearling Karadi lambs were divided into six groups, 4 lambs each, and individually fed on one of the six rations which based mainly on whole barely ( 13% or 15% protein) ( T1&T2), ground barely (13 or 15 % protein) (T3& T4) and ground yellow corn ( 13 or 15% protein ) (T5&T6). All lambs were fed for 10 days as a pre period and 5 days for feces collection. Blood samples were taken from the jugular vein on day 15.Results showed that the physical form of barely had a significant effect on DM, OM, P and EE digestibility. However, protein levels had significant effect only on OM, P, EE and NDF. On the other hand, source of energy had significant effect only on ADF. Interaction results showed that there were a significant interaction between energy source and protein levels on DM, OM, P, EE and ADF digestibility. Results of biochemical analysis of blood pointed that physical form, energy source and protein levels had no significant effect on total protein, albumin and globulin but have a significant effect on glucose, triglyceride and urea concentration
