Methods and procedures for the processing of feather from poultry slaughterhouses and the application of feather meal as antioxidant

Open access


The research subject is the elaboration of a method and procedure for processing feather from poultry slaughterhouses and using it as antioxidant as well as for satisfying the sulphurous amino acid needs of ruminants. We investigated the level of digestion of the meal feather obtained with our technology, its antioxidant effect and role in the rumen fermentation of the ruminants. Making use of the digested feather meal’s antioxidant effect and amino acid composition, we make a suggestion for the preparation to be used as antioxidant and for the satisfaction of the sulphurous amino acid needs of ruminants. By adopting this procedure, the valueless feather can be transformed into a useful feed supplement (natural antioxidant, sulphur source) that can bring about significant economic growth. Pre-trials have been performed successfully, and in what follows we’ll need to prove through field trials and pilot-scale experiments that feather meal can be produced and utilized economically as antioxidant in monogastric animals and as a sulphur source in the studying of ruminants.
