In marked contrast to the fairly extensive range of published information on the fatty acid composition of cow-milk fats, there have appeared relatively few detailed analyses of the milk fats of other farm animals. Dhingra (1933) analyzed the milk fats of Indian goats and sheep by the ester fractionation procedure, using a Willstatter flask, and found them to be closely similar in composition. The two fats differed from cow-milk fat in the higher content of hexanoic, octanoic and decanoic acids and in the lower content of unsaturated C18 acids. Riemenschneider & Ellis (1936) made an investigation of goat-milk fat and reported the presence of monoethenoid C1O, C14 and C1, acids. Investigation by Laxa (1927, 1931) of the milk fat of the mare and of the sow led to a deduction of very approximate proportions of the majorconstituentacids; and, very recently, de la Mare & Shorland (1944) have published a few more data of the major acids of sowmilk fat. The present communication deals with fractionation analyses, using an efficient heated column, of the methyl esters of fats obtained from samples of milks of goat, ewe and mare. The goat's milk was supplied by Mrs G. W. Howard, King's Lynn, Norfolk, from does on a daily.feed of hay, kale, beet, 1-1l lb. groundnut cake, and also 2 hr. pasture; the ewe's milk was sent by Prof. J. G. Wright of the School of Veterinary Science, University of Liverpool; and the mare's milk was obtained from a Shire mare, 8 years old, belonging to Mr H. C. Peers, Oakland Farm, Neston, Cheshire, which was fed on pasture in summgr and on hay with a small amount of crushed oats in winter.  aEwe milk  aGoat milk  aMilk composition  aCaprino  aLeite  aOvino  aComposicao1 aJASPERSON, H.  tBiochemistry Journalgv. 38, n. 5, p. 443-447, 1944.
