Abstract

Trans fatty acids (FA) are produced during the biohydrogenation of linoleic acid in the rumen. Because of their health‐promoting properties, trans‐11 isomers, which are usually the most abundant biohydrogenation intermediates, are most desirable (1). However, in high yielding dairy cows, when high concentrate diets containing fat are fed to cows, a shift from trans‐11 to trans‐10 FA can occur, therefore, trans‐10 isomers can become the predominant biohydrogenation intermediates, inducing milk fat depression in dairy cows(2) and having possible detrimental effects on human health(3). The aim of this work was to study the bacterial community dynamics in response to diet‐induced trans‐10 FA shift.
