Enzymatic feed premix against Gram-negative bacteria colonization in the intestinal tract of animals.

摘要

The invention provides pre-mixture for animal feeding comprising: (a) a polymer or a mixture of polymers, with a content in mannose comprised between 10% and 100%; (b) ²-mannanase enzyme; and (c) an anti-binding agent; wherein the anti-binding agent has an absorptive capacity higher than 20%, and a bulk density which is comprised between 0.10 and 2.70 g/cm 3 . The pre-mixture of the invention diffuses better through the intestinal tract and effectively inhibits the colonization of Gram negative bacteria without affecting the growth of the animal.
