Feed additive with effects of preventing and resisting diseases and improving meat quality and preparation method thereof

Abstract

The invention discloses a feed additive with the effects of preventing and resisting diseases and improving meat quality and a preparation method thereof. The feed additive comprises the following raw materials in parts by weight: 40-70 parts of flos lonicerae or lonicera japonica, 5-30 parts of lonicera japonica leaves, 20-40 parts of forsythia suspense leaves, 5-20 parts of scutellaria baicalensis, 2-10 parts of pine needle, 2-10 parts of eucommia ulmoides leaves, 2-10 parts of herba houttuyniae, 0.1-5 parts of 1000 ppm-organic selenium and 0.1-5 parts of vitamin C. The preparation method for the feed additive comprises the following steps: stewing all traditional Chinese medicinal materials into an extracting tank with water, filtering, concentrating filtrate with alcohol, carrying out vacuum drying at a low temperature when the concentrated solution contains 20-30% of water so as to obtain powder, and mixing the traditional Chinese medicine powder with organic selenium and vitamin C according to the ratio, so as to obtain the feed additive. The feed additive disclosed by the invention has the double effects of resisting bacteria and viruses, can replace antibiotics for preventing and treating epidemic diseases of livestock and aquatic animals, improves the meat quality, decreases pork rancidity speed and remarkably increases the contents of arginine and selenium in pork.

Description

technical field [0001] The invention relates to a feed additive for preventing and resisting diseases of livestock and poultry aquatic products and improving meat quality, and also relates to a preparation method of the feed additive. Background technique [0002] my country's aquaculture industry is the hardest hit area for antibiotic abuse. Experts estimate that 97,000 tons of the approximately 210,000 tons of antibiotic raw materials produced in my country each year are used in animal husbandry, accounting for 46.1% of the total annual output. Antibiotics treat diseases by killing or inhibiting pathogenic bacteria entering the body, and should not be added in large doses to feed, such as adding antibiotics to feed will cause harm to human health and food safety. The first is the emergence of drug-resistant bacteria in animals. The emergence of a large number of drug-resistant bacteria has caused great harm to medical care and society. It may cause the failure of anti-in...
