    Abstract: A method and apparatus for automatically and simultaneously weighing and integrating various nutritional supplements for subsequent blending with livestock feed grain. The apparatus includes a housing formed with a plurality of upper inlet openings and a lower outlet opening. A plurality of augers convey nutritional supplements from a storage area into the inlet openings. A plurality of weigh hoppers are pivotally mounted below the inlet openings on load cells. Weight indicators are electrically connected to the load cells and augers, and are interfaced with a computer, for controlling and coordinating the deposit of supplements from the augers, load cell weighing, and the pivotal dumping movement of the weigh hoppers. A funnel containing a plurality of deflectors is mounted within the housing below the weigh hoppers, and communicates at its lower end with a motor-driven flighted drum rotatably mounted within the housing, which in turn communicates with the outlet opening.
