  • Selective starch feeding protocol
    Patent number: 8940322
    Abstract: The present invention includes a method for improving milk production in a ruminant. An amount of ruminally digestible starch in relation to the dry matter of a feed is manipulated to include a first selected ratio of ruminally digestible starch in relation to the dry matter of the feed which is fed to the ruminant during a first time interval after parturition. After the first time interval, the amount of ruminally digestible starch component in the dry matter of the feed is adjusted to a second ratio, lower than the first ratio, and fed to the ruminant.
    Type: Grant

    Date of Patent: January 27, 2015
    Assignee: Forage Genetics International, LLC

  • On-line pellet durability tester
    Patent number: 5285681
    Abstract: The durability of extruded, uncured animal feed pellets is measured by disintegrating the pellets in a test chamber by means of a rotating blade powered by an electric motor. During the test, the rotating blade is maintained at or near a constant rate of rotation and the time over which an increase of power is necessary to drive the blade at constant rotation is sensed to determine the durability of the pellets.
