Feed additive capable of improving disease resistance of livestock and poultry

Abstract

The invention discloses a feed additive capable of improving disease resistance of livestock and poultry. The feed additive is prepared from the following components by weight: 10 to 20 parts of freeze-dried powder of ginkgo leaf, 15 to 25 parts of olive leaf extract, 13 to 17 parts of wall-broken spirulina powder, 40 to 60 parts of honeysuckle flower extract chlorogenic acid, 15 to 25 parts of dipotassium glycyrrhizinate, 6 to 18 parts of Radix Astragali polysaccharide, 6 to 18 parts of Fructus Forsythiae extract, 6 to 18 parts of isatis root extract and 5 to 15 parts of a composite microbial agent. According to the invention, the olive leaf extract, 13 to 17 parts of wall-broken spirulina powder, the honeysuckle flower extract chlorogenic acid, the Fructus Forsythiae extract, the isatis root extract and the like are obtained through special process and combined with dipotassium glycyrrhizinate, Radix Astragali polysaccharide, the composite microbial agent and the like according to an optimal ratio, so the prepared feed additive has the medical health-care effects like bacteriostatic effect, antiviral effect and growth-promoting effect and does not incur generation of drug resistance.

Description

technical field [0001] The invention relates to a feed additive, in particular to a feed additive for improving disease resistance of livestock and poultry. Background technique [0002] At present, more and more people in the industry realize the potential threat to human health caused by the use of conventional pharmaceutical feed additives such as antibiotics, growth-stimulating hormones, preservatives, antioxidants, and disinfectants in poultry feed. These traditional feed additives have multiple hazards: First, adding antibiotics to feed for a long time will induce the generation of highly resistant microorganisms in poultry and livestock. Because these microorganisms have the ability to resist antibiotics, once they infect the human body, they will cause the disease. There is no cure, which poses a great threat to human beings; the second is that artificially synthesized growth-promoting hormones are added to the feed, which causes abnormal growth of poultry and livest...
