. A differentiated consideration concerning the value of different n−3 fatty acids and isomers
of CLAs is necessary. In ruminants, it is difficult to enrich the meat with n−3 fatty acids due to the extensive
ruminal biohydrogenation of unsaturated fatty acids, but several possibilities to enhance the proportion of the
most desired CLA isomer, rumenic acid, exist. By contrast, pork and poultry meat can be easily enriched with
n−3 fatty acids.
