    Swine production is a strategic economic activity that faces the ongoing challenge of reducing feed costs. In this context, agro-industrial by-products such as cocoa (Theobroma cacao) and coffee pulp may represent viable alternative feed ingredients, provided they are properly evaluated. This study aimed to analyze the in vitro digestibility of five substrates—wheat, corn, cocoa pulp, cocoa husk, and coffee pulp—by assessing variables such as apparent dry matter digestibility, gas production, and chemical composition. The results showed that wheat and corn exhibited the highest digestibility rates, with values of 88,34% and 83,74%, respectively. They also registered the highest cumulative gas production at 96 hours (106,5 mL/g for wheat and 101,40 mL/g for corn). In contrast, cocoa husk and coffee pulp showed lower digestibility values (60,88% and 61,34%, respectively) and significantly reduced gas production (62,92 mL/g and 71,83 mL/g), which is associated with their higher lignin content. Cocoa pulp yielded intermediate results, with 70,8% digestibility and 84 mL/g of gas produced. These findings suggest that, although certain by-products such as cocoa pulp have potential as alternative feed ingredients in swine diets, their inclusion must be based on a detailed evaluation of their nutritional value and digestibility.
