Summary
The fatty acid composition of depot fats from 18 “icterus swine” has been determined. These fats represented back, belly, and abdominal fats. Depot fats from comparable carcass locations in nine normal swine were examined in the same manner. The fatty acid composition of depot fats from “icterus swine” corresponds well with that from the same carcass location of normal swine. The yellow fat in “icterus swine” is believed to be due to bile pigments or similar substances deposited by the pig under the conditions of disease existing in the animal. This yellow fat (from diseased swine) differs from that observed by Beadle,et al. (1), in that it has an apparently normal linolenic acid content whereas they found an abnormal linolenic acid content which they ascribed to dietary effects.
