Abstract
This study was carried out to assess the effect of bacterial additive and fibrolytic enzyme on the in vitro gas production of forage corn silage. For this aim forage corn were harvested and chopped with cutting length about 2 to 4cm. and were mixed with the bacterial additive (0, 0.5 unit 108 cfu/g) and fibrolytic enzyme (0,0/5 and 1 g/kg DM) 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. OM digestibility and metabolizable energy content estimated by gas production (in vitro) method. Results showed that the addition of fibrolytic enzyme caused a significant increased in EE, CP, OM content and reduction in DM, Ash, pH, ADF and NDF content(p<0.05). Addition of bacterial additive caused a significant increased in OM, Ash, EE content and reduction pH, CP, DM, ADF and NDF content(p<0.05).In addition, the findings obtained from in vitro gas production method revealed that the in all times of incubation addition of fibrolytic enzyme and bacterial caused increased. In conclution, considering the changes in NDF, ADF contents and metabolizable energy values in the present study, it can be suggested addition of fibrolytic enzyme and bacterial can be used to make good corn forage silage.
