SIGNIFICANCE OF THE SYNTHESIS OF ESSENTIAL FATTY ACIDS IN SWINE
Cornell University, Ithaca, New York 148533
SUMMARY
An experiment with 29 5-week-old Yorkshire pigs (initial weight 6.5 kg) was completed to study the effects of a fat-free diet on (1) growth rate, (2) body composition and (3) net synthesis of fatty acids. Semi-purified diets consisting principally of glucose and casein were used with or without supplementation of corn oil in a 28-day test. All pigs were caged in pairs in stainless steel metabolism cages and fed ad libitum in three replicates totalling 12 pigs per treatment. Five littermate controls were slaughtered at the beginning of the experiment to provide an estimate of the changes in body composition and net fatty acid synthesis. Weight gain was not significantly affected by the level of fat in the diet and no skin lesions or alopecia were seen in pigs fed the fat-free diet. Pigs fed the fat-free diet contained significantly less (P
