Abstract: The present invention is an apparatus for spraying a liquid onto pelleted feed, having a hopper with a gate for selectively holding or allowing the dropping of dry pellet feed, a spraying chamber below the hopper with an upper portion to receive the dropping dry pellet feed from the hopper, and a cylindrical lower portion, a cone operably attached to a motor, the cone rotatably disposed within the upper portion of the spraying chamber to direct dry pellet feed received into the upper portion into a single layer of falling feed around a circumference of the lower portion, an enzyme chamber, and a nozzle rotatably disposed within the lower portion to substantially evenly spray an amount of liquid from an enzyme chamber on the single layer of falling feed.

Abstract: A method of improving milk yield in a ruminant animal a ruminant ration with an aqueous is presoaked with a solution of a composition of enzymes comprising a xylanase and a ferulic acid esterase.

Abstract: The presence of non-starch polysaccharides (NSP) in the plant cell wall reduces the digestibility and limits the apparent metabolizable energy (AME) and performance of animals. The main chain degrading enzymes, especially xylanase, cellulase and glucanase play an important role in improving the digestibility of NSP in the feed. Ferulic acid esterase (FAE) breaks the ferulate cross linkages in the plant cell wall, and aids the main chain hydrolases to further degrade the plant cell wall. The present study investigated the synergy of FAE in combination with main chain degrading enzymes in improving the AME of birds fed with high fiber diet. The addition of FAE improves the access of main chain degrading enzymes, digestibility of high fiber diet, AME in layers and broilers, Body weight and reduces FCR in broilers.
