The effects of microbial fermented liquid (MFL) supplementation on rumen fermentation and digestibility of dairy steer using in vitro gas production technique was studied. The two rumen fistulated dairy steers as a rumen fluid donor was used. The levels of source of microbes (yeast (Y) and microbial fermented liquid (MFL) were incorporated with the levels of supplementation (0, 10, 20 and 30 % of concentrate) was recorded. It was found that the intercept value (a) and IVDMD and IVOMD were interacted (p<0.01) between microbial source and supplement levels, while, supplement levels affected on a and the insoluble fraction (b), microbial source affected on b, potential extent of gas production (a+b) and cumulative gas production at 72 h and IVOMD. Moreover, supplementation of MFL with 20 % of concentrate were the highest (p<0.05) of b, c, a+b, cumulative gas production at 72 h, IVDMD and IVOMD. In conclusion, supplementation of MFL could improve nutritional digestibility and a possible productivity in ruminants.
