Influence of Fatty Acids on In Vitro Rumen Fermentation
Original language description
This in vitro study evaluated the effect of four medium-chain fatty acids (MCFA, i.e., caprylic (C8:0), capric (C10:0), lauric (C12:0), and myristic acid (C14:0)), used alone or in binary combinations, together with nitrate (NT) on rumen fermentation and methane (CH4) production. Using a 24 h batch incubation, the experiment showed that all the MCFA+NT treatments reduced (P<0.001) CH4 production; the most potent treatment being C10:0+NT and the least effective C14:0+NT. Notably, the treatments had no effect (P=0.051) on apparent dry matter disappearance (aDMd) and net production of volatile fatty acids (nVFA), which shows that fermentation of feed was not adversely influenced. These results show the benefit of combining lower doses of feed additives with complimentary modes of action to enhance rumen fermentation.
