Determination of the Use of and Application on Fermentation Profile and Chemical Composition of Corn Silage.

Corn was inoculated with and subsp. either independently or as a mixture at ensiling, in order to determine the effect of bacterial additives on corn silage quality. Grain corn was harvested at 32-37% of dry matter and ensiled in a 4 L laboratory silo. Forage was treated as follows: bacterial types: B0 (without bacteria-control), B1 , B2 ( subsp. ), and B3 (combination of and subsp. ). Each 2 kg of chopped forage was treated with 10 mL of bacterial culture and allowed to ferment for 27 days. The first experiment determined the most suitable wavelength for detection of bacteria (490 nm and 419 nm for B1 and B2, resp.) and the preferable inoculation size (1 × 10 cfu/g). The second experiment analysed the effect of B1 and B2 applied singly or as a mixture on the fermentation characteristics and quality of corn silage. alone increased crude protein (CP) and reduced pH rapidly. In a mixture with , the final pH was the lowest compared to other treatments. As a mixture, inclusion of bacteria resulted in silage with lower digestibility than control. Corn silage treated with or either alone or mixed together produced desirable silage properties; however, this was not significantly better than untreated silage.
