    AnnotationBackground: A giant amount of poultry waste represents one of the threats to the environment, or conversely, a significant source of peptides and other substances in demand. Rational use of huge quantities of poultry waste, especially after industrial chicken processing, is one of the pillars of biorefinery of animal wastes.
    Introduction: Six different animal wastes: chicken feathers, cartilages and the residue after meat separation, sheep wool, rabbit hair, and the rest of the goose feathers from blankets after cleaning were chosen for a hydrolysis test with malic acid as the initiator.
    Result: The newly designed hydrolysis of animal wastes at 140 oC with malic acid for initiation was successfully verified for all animal wastes. The resulting hydrolysates contained a mixture of amino acids, peptides, proteins, glycoproteins, and no salts.
    Conclusion: Hydrolysate applications for agriculture was successfully tested as a biostimulant in the form of a 10% water solution.
