The neutral lipids of the skin from the feet of turkey poults fed a biotin supplemented or a biotin deficient diet consist mainly of triacylglycerols, and of mono‐ and diester waxes. Diester waxes from both groups were characterized as fatty acid esters of erythro ‐2,3‐alkanediols. A comparison between fatty acid composition of the two groups, however, revealed the following significant differences. Biotin deficient birds showed a fairly high concentration of very long chain fatty acids (C 36 –C 40 ) which were completely absent in biotin supplemented birds. Further, almost one‐third of the fatty acids of diester waxes in biotin deficient birds were unsaturated while those from biotin supplemented birds were predominantly (96%) saturated.
