Supplements for Distillers’ By-Products in Poultry Breeding Diets

Economies in the use of animal by-products in poultry rations: II. Vitamin and amino-acid provision for laying hens

“…As mentioned in the introduction, it was demonstrated before 1930 that a high level of egg production could be attained in birds on range and fed certain combinations of plant products, provided that supplements of calcium, phosphorus and chloride were given to replace the minerals contributed by animal by-products in mixed rations. More recent experiments have shown that other combinations of plant products are also capable of maintaining high egg production by birds kept on pasture (Lomax, 1930;Hale & Bolton, 1948), on built-up litter (Sehlamb & Winter, 1948;Kennard & Chamberlin, 1951;Sunde et al 1952;Petersen, Lampman & Wiese, 1952), on solid-floored laying houses with no attempt to create built-up litter conditions (Temperton & Dudley, 1940-1;Heuser & Norris, 1944;Bethke, Record, Kennard & Chamberlin, 1946;Whitson, Titus & Bird, 1946;Winter & Sehlamb, 1948), and in laying batteries (Temperton & Dudley, 1939-40;Parkhurst, Fellers & Kuzmeski, 1945;Parkhurst & Kuzmeski, 1946).…”

An Evaluation of Dried Distillers Feedstuffs Fed to Chickens Throughout Their Life Cycle

“…Egg production, egg weight, body weight, egg quality and feed efficiency were compaable with all four rations; but hatchability was lessened when substitutions were made in the breeding ration. Parkhurst, Fellers and Kuzmeski (1945) and Parkhurst and Kuzmeski (1946) reported on the use of dried distillers feedstuffs in rations for egg production and hatchability when fed as allmash to pullets kept in individual laying batteries. The basal rations contained 2.5 percent dehydrated alfalfa meal, and soybean oil meal as the chief source of protein.…”
