摘要
Systems and methods measure ruminal undigested fiber fractions in a feed by sampling forages and grains from available feed sources, analyzing the samples to determine a starting NDF value and an ending NDF value after ruminal digestion, calculating a ruminal undigested NDF fraction based thereon; and calculating a feed ration using the ruminal undigested NDF fraction and feeding rates of the analyzed samples. Systems and methods reduce feed costs or improve milk production by analyzing feed components in a feed ration fed to a lactating ruminant, comparing the analyzed results with a feed formulation stored in memory, where the feed formulation is for controlling a rate and extent of fiber and starch digestion in the rumen, and reformulating the feed ration based on the comparison. The rate of fiber digestion may be controlled based on a determination of the ruminal undigested NDF fraction of the analyzed feed components.
