Webquent chick growth. Chicks from hens fed an alpha-protein-glucose purified diet were reported to be depleted of unidenti fied growth factors by Waibel et al. (1955). However, hatchability of fertile eggs was about the same for hens fed a purified diet, a corn-soy diet, or a corn-soy diet supplemented with fish solubles and whole desiccated liver. WebFresh or dried yolk was shown to contain an unidentified chick growth factor (s) not identical with the fish solubles factor. Preliminary fractionation procedures have shown that the active principle is fat soluble since it can be extracted from dried yolk by the common fat solvents. The yolk factor is not identical with oleic acid, linoleic acid, or lecithin. The non …
