A composition and production of feed pellets are provided. In some embodiments, biomass is milled to less than around ⅜ inch. Biomass may include corn cobs and corn stover in (substantially) equal proportions, or may include a minimum of about 20% corn cobs. The biomass, dried distiller's grains with solubles, distillers solubles, and binders are mixed. In some embodiments, the ratio of ingredients is, on a w/w dry matter basis,: about 30-50% milled biomass, about 45-65% dried distillers grains, less than about 6% distillers solubles, and about less than around 2.5% binder. Once mixed, the ingredients may be conditioned using steam and extruded through a die of between ¼ and 3.5 inches in size. The pellets are cooled. The final pellets include about 13-21% protein, about 4-9% fat, about 25-45% neutral detergent fiber, and about 5-20% moisture. Further, the pellets possess a pellet durability index of greater than around 94%.
