Abstract: © 2016 Elsevier Ltd This article reviews opportunities for enriching the lipids of meat with n − 3 fatty acids and conjugated linoleic acids (CLAs), both considered beneficial to human health. Special focus is put on feeds available and research carried out in Thailand. 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. With purified CLA sources, CLAs also can be enhanced, but it is difficult to achieve this exclusively for rumenic acid. An interesting approach might consist in supplementing the CLA precursor vaccenic acid instead. Possible constraints for meat quality and in the fatty acid levels achieved are outlined.
