    The valorization of agro-industrial by-products represents a sustainable alternative to improve the availability of feed resources for small ruminants. The aim of this study was to evaluate the in vitro ruminal fermentation of avocado (Persea americana) and Dominico plantain (Musa paradisiaca, AAB group) and to determine their potential as feed ingredients for sheep. To achieve this, the chemical composition of peel and pulp fractions was characterized, and their degradability and fermentative kinetics were assessed through in vitro incubations, recording gas production and dry matter degradability considering a passage rate of 6%/h. Chemical composition differed significantly between by-products and fractions (P < 0.01). Pulps exhibited higher dry matter contents, whereas plantain peel showed the greatest concentrations of total ashes. Plantain contained higher levels of non-structural carbohydrates, while avocado presented greater ether extract values. In the in vitro fermentation assay, plantain fractions displayed higher potential gas production, greater fractional rates, and shorter lag times (P < 0.01), indicating a faster fermentability. Avocado fractions showed slower rates, likely associated with their higher lipid content. Gas production curves reached their stationary phase at approximately 36h. In conclusion, both by-products possess valuable nutritional attributes; however, plantain exhibited greater fermentative potential, whereas avocado requires more cautious inclusion in sheep diets due to its lipid content.
