Abstract

A comparison of free‐range, deep litter and battery hens' eggs in relation to their fatty acid content has been made. Aorta lipids and aortic sudanophilia have been examined. The body fat of birds of various age has been analysed by gas‐liquid chromatography. The importance of making egg lipid assays under strictly comparable conditions in the laying cycle is emphasised. Dietary influences on the essential fatty acid content of eggs are reviewed and the possible significance of these and the present results are discussed in relation to human atherosclerosis. The various systems of modern husbandry examined are thought to have little significance in this problem.
