Abstract
A potential effect of the specific composition of plant oil triacylglycerols, with PUFAs predominantly esterified at the sn-2 position, on the fatty acid composition of adipose tissues of pigs was investigated. Two blends with a ratio of 1/3 and 3/1 of soybean oil and beef tallow were randomised or left unmodified and fed at 4% of a conventional diet to 4 * 12 pigs. The randomisation of fatty acids at sn-1, 2 and 3 positions did not affect the fatty acid composition of pig adipose tissues. It is concluded that the position of PUFA in dietary triacylglycerols is of minor relevance for the composition of depot fat in growing-finishing pigs

Summary
Résumé : L'effet potentiel d'une huile végétale contenant des triacylglycérols ayant en position sn-2 principalement des acides gras polyinsaturés sur la composition du tissu adipeux de porcs a été étudié. La position des acides gras polyinsaturés dans les triacylglycérols contenus dans la diète n'a que peu d'influence sur la composition du tissu adipeux chez les porcs à l'engrais.
