Rumen Fermentation Parameters As shown in Figure 2 , compared to RTW, the concentrations of acetate ( p = 0.04), propionate ( p < 0.01), isobutyrate ( p = 0.02), and T-VFAs ( p < 0.01) in the rumen fluid of HW significantly increased, while the ratio of acetate to propionate showed a decreasing trend ( p = 0.06) of HW. 3.3.
