1. Comparison was made between the utilization of essentialfatty acid (linoleic acid) in corn oil and the urea-inclusioncompound of its ethyl ester. Changes in dermal symptoms andsynthesis of arachidonic acid indicated that the essential fattyester was active when administered in the form of its inclusioncompound.
2. Vitamin A content of rations was found to decreaseless overa period of 40 days if the essential fatty ester inthe dietis present as urea-inclusion compound.
3. The useof urea-inclusion compounds of essential fatty acidsis recommendedas a means of supplementation by way of the ration,therebyaffording protection of these unstable substances againstautoxidativerancidity, and providing steady dosage.
