Effect of Changing the Molar Ratio of Acetate to Propionate in Rumen Fluid on Rumen Fermentation and Some Blood Indexes

The four designed VFA infusions with different molar ratio of acetate:propionate:butyrate were used to establish final molar ratio of VFAs in the rumen of the sheep.It was found that the proportion of propionate in the rumen fluid at steady state increased with the increase of propionate in the mixture of VFAs,and the concentration of acetate was down gradually and different from un infused contro…
