  • Formulation for treating silage containing .beta.-1,4-xylanase and .beta.-1,3-xylosidase but essentially free of .beta.-1,4-glucanase and .beta.-1,4-cellobiohydrolase, and one or more lactic acid-producing bacteria
    Patent number: 5432074
    Abstract: A formulation consisting essentially of -1,4-xylanase and -1,3-xylosidase, but essentially free of -1,4-glucanase and -1,4-cellobiohydrolase and on or more lactic acid-producing bacteria is disclosed. The formulation can be used in a silage composition to stabilize silage from cereal and other crops and to enhance its nutritive value and digestibility in a ruminant or other animal.
