Corn Distillers’ By-Products in Poultry Rations : II. Laying and Breeding Rations

Abstract

BY-PRODUCT feeds recovered from the manufacture of alcohol from grains are materially adding to the supply of high-protein feeds and are resulting in a substantial reduction in the cost of producing alcohol for wartime uses. According to Jacobs and McBride (1943), for each gallon of alcohol produced, 0.4 bushel of corn is required and 3.8 pounds of corn distillers’ dried grains, containing 28 to 30 percent protein, are recoverable. As additional complete recovery equipment is installed, there should be a substantial increase in the supply of the dried by-products for use in both present-day and post-war feed mixtures. The Association of American Feed Control Officials (1944) recognizes three dried distillers’ by-products from corn: corn distillers’ dried grains, referred to hereafter as “screenings”; corn distillers’ dried grains with solubles, hereafter referred to as “grains”; and corn distillers’ dried solubles, hereafter referred to as “solubles.”Shea, Fellers, and Parkhurst (1941) and Nelson, .
