The ruminal ratio of trans-10/trans-11 fatty acids obtained in vitro reflects in vivo values and strongly depends on the diet of the donor cow

Abstract : Trans-10 and trans-11 fatty acids (FA), originating in ruminal biohydrogenation of unsaturated dietary FA, would have negative and positive effects on human health, respectively (Tricon et al., 2004). A large variability in the ratio of trans-10 to trans-11 isomers (t10/t11) has been observed in milk fat (Shingfield et al., 2006). Some dietary factors shifting from t11 to t10 have been identified, like the proportion of concentrate (Griinari et al., 1998), or the addition of oil (Roy et al., 2006). The aim of the present study was to investigate if the ruminal fluid of a cow having the t11 to t10 deviation results in the same deviation during in vitro batch incubation and if the pathway of biohydrogenation in vitro depends mainly on the donor cow or on the fermentative substrate.
