Ensiling Characteristics of Sainfoin(Onobrychis viciifolia) addition with or without of Polyethylene glycol (PEG)

Protein degradation usually happened during legume ensiling attributed to high (20%) protein contents. Condensed tannins have several bioactivity such as inhibit bacteria and fungi , decreased protein degradation by combine with protein , etc.Sainfoin (Onobrychis viciifolia) is a legume rich in condensed tannins.Several studies use polyethylene glycol (PEG) deactivated CT at ensiling to observed tannins impact.Thus objected to present study is to find out condensed tannins impact on Ensiling Characteristics of Sainfoin(Onobrychis viciifolia) addition with or without of Polyethylene glycol (PEG).Established 2 treatments (with and without addition of PEG) × 5 sampling time points (3,7,14,30,60 days of ensiling) × 3 replicates samples silages. Using two-way ANOVA for a 2×5(PEG and control treatments× five ensiling time days) to data analysis (IBM SPSS 22.0 software, New York, USA).The data collected from different fermentation days include contents of dry matter, dry matter loss, crude protein,Non-Protein Nitrogen, soluble protein, Neutral detergent -insoluble protein, Acid detergent -insoluble protein, Neutral detergent fiber, Acid detergent fiber, Extractable condensed tannins , Protein-bound condensed tannin, Fiber-bound condensed tannin, total condensed tannin, water soluble carbohydrates, ammonia nitrogen, lactic acid, acetic acid, propionic acid, Lactic acid bacteria, Aerobic bacteria, yeast , moulds.
