Linoleic Acid in Association with Malate or Fumarate Increased CLA Production and Reduced Methane Generation by Rumen Microbes
An in vitro study was conducted to investigate the effect of propionate precursor (malate or fumarate) on fermentation characteristics, production of conjugated linoleic acid (CLA) and methane (CH4) by rumen microbes when incubated with linoleic acid (C18∶2) as a CLA precursor. Total CH4 production for 12h incubation, however, was greatly reduced (P＜0.0001) by all the supplements compared to that of control, and its production from M-LA or F-LA treatment was smaller than that from LA treatment. Supplementation of M-LA or F-LA also increased concentrations of cis9,trans11-CLA (P<0.039-P<0.001) for all incubation times and trans 10,cis12-CLA at 1h (P<0.013), 3h (P<0.036) and 12h (P<0.025) incubation times compared to LA supplementation.
