The invention belongs to the technical field of formula design and
machining process of feeds, and particularly relates to a novel roaster biological feed and a preparation method thereof. The novel roaster biological feed comprises the following raw materials in parts by weight: 10-12 parts of extruded corn, 12-14 parts of extruded wheat, 15-17 parts of high-
protein extruded bean pulp, 22-27 parts of northeast maize, 2-4 parts of imported
fish meal, 6-8 parts of whey
powder, 2-3 parts of first-grade bean oil, 7-10 parts of Chinese
medicinal herb fermented matter, 10-14 parts of premix A and 2-4 parts of premix B. The preparation method comprises the following steps of: secondarily crushing and mixing the raw materials, preparing into a particle semi-finished product and a
powder-shaped semi-finished product, and mixing the particle semi-finished product with the
powder-shaped semi-finished product to obtain the novel roaster biological feed. The novel roaster biological feed is reasonable and effect in formula; and through a mutual cooperation action of the Chinese
medicinal herb fermented matter, an enzymic preparation and a microbial ecological agent in the formula, the
gastric acid secretion state of a roaster can be well regulated, the development of intestinal tract villusin is improved, the immunologic mechanism of the roaster is improved, the feed desire of the roaster is promoted, the increase of
food consumption of the roaster is promoted, and the
weaning stress effect of the roaster is delayed.
