The Utilization of Hydrolyzed Poultry Feathers in Isonitrogenous and Isocaloric Broiler Rations

THE increased production of hydrolyzed poultry feathers (HPF) in both the United States and Canada, coupled with the changing economy, prompted us to search for published work on its replacement value for soybean meal. The advantage of HPF lies in its high protein content. When used in broiler feed, it takes less HPF than soybean meal to supply the same amount of protein. As a result, more corn can be incorporated in the formula. This in turn reduces the amount of added fat needed to supply the same amount of energy. If this interrelationship holds true, it provides the broiler industry with the opportunity to take advantage of price fluctuations of these feedstuffs. The use of HPF in poultry feeds has been reported by numerous authors. Naber (1961) made a review of the reports published in 1961 and earlier, and arrived at the conclusion that HPF, after proper processing, can…
