Abstract

This study was carried out to evaluate changes in chemical composition and nutritional value of edible mushroom waste silage in respons in enzymes and molasses. For this aim edible mushroom waste were prepared and chopped with cutting length about 2 to 4cm. The chopped edible mushroom waste then were mixed with the urea (3 g/kg DM), molasses(10%) and ensiled in 5 Kg plastic baskets. The silages were opened after 45 day and chemical compositions inculuding dry matter (DM), organic matter (OM), Ash, ether extract (EE), crude protein (CP), cell wall (NDF) and cell wall without hemicelluloses (ADF) fractions were measured according to the standard procedure. Dry matter digestibility, metabolizable energy content and dry matter degradability were also determined by gas production (in vitro) and nylon bags (in situ) methods. Results showed that the addition of enzymes caused a significant increased in DM, OM, CP and EE content and decreased PH, Ash, ADF and NDF content. Addition of molasses caused a significant increased in DM, OM, CP and EE content and decreased PH, Ash, ADF and NDF content. The in situ degradability out puts indicated an increased DM degradability. In addition, the findings obtained from in vitro gas production method revealed that the time incubation addition of enzymes and molasses caused decreased. In conclution, considering the changes in cell wall contents, hemicelluloses contents and degradability values in the present study, it can be suggested that the use of supplements enzymes and molasses can be used to make good edible mushroom waste silage
