XIn ruminants, dietary unsaturated fatty acids (FA) are extensively isomerized and hydrogenated by rumen microbiota, which leads to the low content of polyunsaturated FA (PUFA), and variable but ubiquitous presence of trans FA in their tissues and products. Some of trans FA derived, directly or indirectly, from rumen biohydrogenation pathways like vaccenic acid (t11-18:1) and rumenic acid (c9,t11-18:2) have been reported to exert anticarcinogenic activities and other health promoting effects in several biological models (Gebauer et al., 2011; Lim et al., 2014).
