    Agro-industrial by-products that are not used in the main production chain are eliminated into the environment and generate polluting gases, causing environmental alterations. Stems and leaves that are not suitable for commercialization make up a considerable part and have the potential to be widely included in the guinea pig feed industry. On the other hand, the use of in vitro techniques to determine the digestibility of feed in guinea pigs is limited and not standardized, therefore, the objective of this study was to evaluate the nutritional value of agro-industrial by-products and implement an in vitro technique to determine the digestibility of dry matter on guinea pigs. The by- products showed contents of 13, 7.5, 50 and 29% of crude protein, ether extracts, nitrogen-free extracts and crude fiber, respectively. Total digestible nutrients were around 80% with metabolizable energy contents between 3549 kcal ME/kg of DM and 3928 kcal ME/kg of DM in all agro-industrial by-products. In conclusion, agro-industrial by-products such as broccoli, cabbage, sugarcane bagasse and corn leaves can be used as an energy source in guinea pigs' diet, replacing cereals and forages
