Abstract: A method of processing colostral whey includes contacting the whey with one or more filters, at least one of which has an average pore size of no more than about 50 nm. During this contacting step, the whey encounters a pressure of no more than about 200 kPa. This contacting step can be preceded by contact with another filter which has an average pore size of no more than about 0.3 m, with this step also being performed at a pressure of no more than about 200 kPa. The result is a filtrate of colostral whey that includes peptides, no more than 10% of which are denatured.

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.
