The invention provides a composite
plant extract
feed additive for preventing
swine dysentery. The composite
plant extract
feed additive is mainly prepared from the following components of 5-10 parts of
Chinese gall tannic acid, 20-50 parts of a
plant essential oil composite, 3-6 parts of garlicin, 3-6 parts of
lauric acid and esters thereof, 3-6 parts of acanthopanax
polysaccharide, 3-6 parts of a solubilizer and 42-50 parts of carriers, wherein the plant
essential oil composite is mixed and compounded from 3-6 parts of
rosemary oil, 5-10 parts of
thyme oil, 3-6 parts of folium eucalypti oil and 10-25 parts of cretian
origanum oil. The addition proportion of the composite plant extract accounts for 0.01%-0.3% of a pig feed. The composite plant extract
feed additive is prepared from natural plant extracts, can effectively prevent
swine dysentery, and protect large intestines and caecums from being damaged by serpulina hyodysenteriae. In addition, through the composite plant extract feed additive disclosed by the invention, the
immunity of animals can also be adjusted, the occurrence rate of diarrhoea and respiratory diseases can be reduced, and the growing performance of the animals is improved. The composite plant extract feed additive can be applied to pigs at various growth phases, is free from residues of
veterinary drugs, does not have
withdrawal time, does not generate
drug tolerance, and is a novel green feed additive for preventing the
swine dysentery.
