Effects of dietary fats of vegetable and animal origin on lipid synthesis in pigs
1995
: We have compared the effect of dietary fats, unsaturated (rapeseed oil: RO) or saturated (cow milk: CM), on growth performance, lipogenesis and fatty acid composition of backfat. Both group had the same food intake and growth performance. Nevertheless, the percentage of body fat increases with the diet RO (P < 0.05). Lipogenesis enzyme activities of backfat were greater with RO than with MC. Then, it appeared that pigs fed diets containing high level of unsaturated fat with long-chain fatty acids have both greater lipogenesis and carcass fatness as opposed to pigs fed diet containing saturated fat with medium-chain fatty acids. The fatty acids composition of lipids deposited with RO diet may alter the technological qualities of adipose tissues and that of meat.
