Compared with the control (no additive), EPQ decreased the dry matter digestibility and the total VFA production (P<0.05), and increased the ratio of acetate and propionate. Both EPQ and yeast culture increased the final rumen pH (P<0.05), but monensin had a negative effect on decline of rumen pH. In conclusion, the addition of EPQ can efficiently retard rumen fermentation rate of wheat starch in vitro , and increase the final pH of ruminal fluid. AU - Wei, J. A. AU - Xin, H. S. AU - Meng, Q.
