The objective of this study was to investigate the effect of papaya peel addition on the quality and in vitro ruminal digestion of napier grass silage. Fresh napier grass was mixed with papaya peel at 0% (control), 15%, 30%, and 45% of fresh weight and ensiled under anaerobic conditions. After fermentation, silages were analysed for pH, organic acids, ammonia-N, and nutrient composition. In vitro ruminal fermentation was conducted using the rumen fluid collected from buffaloes to assess gas production, volatile fatty acid profiles, and hydrogen release. The results showed that papaya peel addition significantly...
