RESUMO
During this activity, tomato pomace as food industrial waste beside two agricultural wastes dry olive wastes [branches and leaves] and lentil straw as well as combination mixtures of them in a ratio of 1:1 were me starting materials of the current work. After chemical evaluation of the previous wastes, they were subjected to fungal treatment using a strain of white rot fungi [Pleuroteus ostreatus] [10% based on dry weight]. The obtained data revealed an increase in protein content ranged 30- 40% as well as an appearent decrease in lignocellulosic materials [lignin, cellulose, hemicellulose], a fact that is considered to be a promising screen of the use of these treated wastes as applied and useful non traditional feed stuffs. These results were confirmed by in-vitro digestibility determination
