Extract

The nutritionally important fatty acid cis-9, trans-11 18:2 (conjugated linoleic acid, CLA) is formed from the major plant fatty acid cis-9, cis-12 18:2 in the rumen. An important intermediate in the biohydrogenation process is trans-11 18:1 (18:1 tr) and CLA is also synthesized from 18:1 tr in adipose tissue by the action of stearoyl CoA ∆-9 desaturase. Diet is known to affect CLA levels in meat (particularly adipose tissue) and this study examined the effects of a predominantly grass or concentrate diet fed to cattle and slaughtered at 3 ages.
