A Preliminary Study on the Value of Condensed Fish Solubles for Turkey Poults

Previous workers, Lassen and Bacon (1946), Cravens, et al. (1945), have shown that condensed fish solubles is a valuable supplement for chicks fed diets containing adequate amounts of riboflavin. Berry, et al. (1945) fed chicks a basal ration containing riboflavin, Vitamin D, and minerals to supplement ground yellow corn and soybean oil meal. They found that 2% condensed fish press water added to this diet apparently supplied other growth factors. Pratt and Biely (1945) secured favorable results with chicks by adding to a soybean basal ration a concentrate of the liquors from the wet-rendering of fish products. Mishler et al. (1947) obtained significantly better growth by supplementing a corn and soybean oil meal ration containing 1.5% condensed fish solubles and synthetic riboflavin with niacin, calcium pantothenate, choline chloride and methionine. When fish solubles and riboflavin were compared with the four synthetic vitamins and methionine (without fish solubles), the results gave . . .
