Young pigs of 13 to 22 days of age, weaned at 7 days, were used to determine the digestibilities of corn oil, lard and tallow; the mean corrected digestibilities were 86, 81 and 56%, respectively. At 22 days of age, the animals were slaughtered and the fatty acid composition of samples from the contents of six different regions of the digestive system were examined by gas-liquid chromatography. The contents of the digestive systems of a conventional and a germfree pig which had been receiving the same diet were also examined. The low digestibility of stearic acid and the high digestibilty of oleic and linoleic acids appeared to be a result of microfloral activity rather than a direct result of the pig’s ability to absorb these fatty acids.
