The Effect on the Growth of Fryers of Adding an Aureomycin Fermentation Product to a High Energy Fryer Ration

Abstract

The purpose of this note is to record the results of a series of experiments which show that the addition of an aureomycin fermentation product will significantly increase the growth response of fryers fed a “high energy” fryer ration.In the experiments conducted, the “high energy” fryer ration recommended by the Poultry Council of the State College of Washington was used as the control ration. The approximate percentage composition of the control ration, as used in each trial, was as follows: ground yellow corn 66.6, dehydrated alfalfa 1.0, herring fish meal 6.8, soybean oil meal 20.0, liver meal 1.0, butyl fermentation product (500 γ riboflavin/gram) 1.0, limestone flour 2.1, dicalcium phosphate 1.0, iodized salt 0.5, and manganese sulfate 0.0125. In each experiment, the quantities of corn, soybean oil meal, and mineral supplements were varied so as to provide 21 percent protein, 1.4 percent calcium, and 0.7 percent phosphorus when using .
