Using some industrial and agricultural wastes for the production of animal feed through biotechnology

ABSTRACT

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 11 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
