Description
Hydrolyzed feather meal (HFM) is the product resulting from the treatment under pressure of clean, undecomposed feathers from slaughtered poultry, free of additives and/or accelerants. Feather meal contains approximately 85% crude protein (dry matter basis) of which 30% is degraded in the rumen. Although HFM has a relatively poor balance of amino acids, it is a good source of sulfur because of its high cystine content. It should contain not less than 75% digestible crude protein as measured with pepsin-HCl. Studies at the University of Florida using 3 to 6% HFM in corn silage-based total mixed rations resulted in milk production equal to that obtained using soybean meal rations.
