In order to carry the digestibility trails, nine adult Barki Sheep (42 Kg average weight) were used. The first six sheep were males and used for digestibility trails. The other three sheep were females fitted with rumen permanant fistula to estimate rumen fermentation patterns. Lactating cows were arranged in 4x4 Latin square to perform the lactation experiment. Flax straw was used as roughage in the four experimental diets as follows:-1- Untreated flax straw (FS), control. 2- Treated flax straw with urea ( 4% , UFS ) F 3- Treated flax straw with fungus (Trichoderma viride , FFS ) 4- Treated flax straw with urea (4%) then with the fungus (UFFS). Flax straw diets were offered to animals ad-libkum, while concentrate feed mixture (CFM) was offered according to NRC (1985) for sheep and NRC (1988) for dairy cows.
