This work aimed to evaluate the effects of dried apple pomace (DAP) on fermentation characteristics and proteolysis alfalfa silages. The was ensiled with (1) no additives (control), (2) 5% DAP, (3) 10% DAP (4) 15% based fresh weight (FW) for 1, 3, 7, 14, 30 60 days, respectively. With increasing proportion lactic acid bacteria (LAB) count, (LA) dry matter (DM) content linearly (p < 0.05) increased, while pH, acetic (AA), propionic (PA), butyric (BA) ammonia nitrogen (NH3-N) decreased during ensiling. silages had significantly lower aerobic (AB), yeast enterobacteria counts than control contents nonprotein (NPN), peptide (peptide-N) free amino (FAA-N) activities carboxypeptidase, aminopeptidase proteinase as increased On day 60, addition tryptamine, phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine, spermine total biogenic amines compared control. As ratio threonine, valine, isoleucine, leucine, phenylalanine, lysine, histidine, arginine, aspartic acid, serine, glutamic, acids, crude protein (CP) water-soluble carbohydrates (WSCs) glycine, alanine, cysteine, proline 60. Overall, optimal indicated by better quality less other treatments.
