Supplements for Distillers’ By-Products in Poultry Breeding Diets

PROGRESS in the use of corn distillers’ dried by-products in breeding rations was reviewed by Parkhurst, Fellers and Kuzmeski (1945). They reported unsatisfactory hatchability when corn distillers’ dried grains without solubles replaced dried skimmilk. However, the hatchability of fertile eggs was good when diets were fed containing meat scraps and no dried skimmilk and corn distiller’s dried grains with solubles up to 20 percent replaced all of the soybean oil meal and part of the ground barley and wheat bran. With fishmeal as a supplement, either 5 percent grains with solubles or 3.5 percent of corn distillers’ dried solubles satisfactorily replaced 2.5 percent dried skimmilk. Fish meal proved a more valuable supplement to corn distillers’ dried by-products than meat scraps for hatchability. The studies were continued in order to investigate further the effect of certain supplements to distillers’ by-products on hatchability. EXPERIMENTAL The distillers’ by-products3 used in these studies were . . .
