The invention discloses a special
feed additive for animal intestines. The
feed additive is prepared from the following raw materials in percentage by weight: 15-20% of an
enzyme preparation, 30-60% of a
fermentation material, 10%-20% of
bentonite, 0.5%-1% of multi-
vitamin, 1%-5% of multi-mineral, 0.5%-2% of a
mildew preventive, 0.5%-2% of an
antioxidant, 2%-20% of
zeolite powder, wherein the
enzyme preparation is a plurality of compound enzymes such as
protease,
cellulase, glucolase and
xylanase, the
fermentation material is a substrate for
fermentation of a microecological preparation, the multi-
vitamin comprises
vitamin A, vitamin D3,
vitamin E,
vitamin B1 and
vitamin B2, the multi-mineral comprise a plurality of trace elements:
copper glycinate,
zinc glycinate and iron glycinate, the main components of the
mildew preventive are propionic acid,
calcium propionate and
benzoic acid, and the main components of the
antioxidant are ethoxyquinoline and
butylated hydroxytoluene. The special
feed additive for animal intestines is high in overall
utilization rate, improves the
egg laying efficiency of old laying hens, and can be widely popularized and used.
