1924] UNIVERSITY O F ILLINOIS 29 5. That should conditions arise which make it desirable to secure a limited number of goats for the investigation of certain problems in milk production, the same should be under the direction of the Department of Dairy Husbandry. Henry B. Ward J Howard Beard . L. A. Adams Wm. G. Kammlade W. W. Yapp Members of the Committee GOAT'S MILK VS. COWS MILK IN INFANT FEEDING J. Howard Beard, M.D. January 3, 1924 (1) "Goat's milk is the nearer in chemical composition to that of mother's milk." The following analyses show that in reality there is so little difference between goat's and cow's milk that the advantages that either has over the other in its approach to human milk is too small to be of consequence in feeding the average infant. 1.
