IntroductionIncluding pasture into the diet, results in higher amounts of ruminal bio hydrogenation intermediates like conjugated linoleic acid isomers (CLA) (Kelly et al 1998; Villeneuve et al 2013). They can be detected in milk. By feeding TMR from hay, silage and concentrate, the total CLA concentration in milk drops significantly below milk from pasture. The most researched CLA isomers are the ...

AbstractDuring natural grazing of pasture, ruminal bio hydrogenation of unsaturated fatty acids leads to the formation of intermediates which are known as CLA (conjugated linoleic acid) isomers. Some of them, like the trans-10/cis-12 isomer are responsible for the observed reduction on milk fat concentration under grazing conditions. Supplementing silage-concentrate diets of transition dairy cows ...
