Problems solved by technology

[0002] In recent years, with the rapid development of my country's pig industry, the degree of intensification has increased, domestic and foreign livestock and poultry trade has become increasingly frequent, the opportunity for disease transmission has increased, infectious diseases are frequently prevalent, mixed infections of various types of pathogens, and the hazards of immunosuppressive diseases Increased, resulting in poor vaccine immunity, seriously affecting the development of the pig industry
At the same time, due to high-density breeding and poor management, the stress response of farmed animals is often triggered, resulting in the suppression of the body's immune system, resulting in frequent occurrence of diseases and bringing huge economic losses to farmers.
The extensive use of antibiotics to ensure animal health has become a common measure adopted by most farmers, and the resulting increase in the resistance of pathogenic bacteria to antibiotics and the decline in the quality of meat products have seriously affected human health

Abstract

The invention discloses a swine immunopotentiator and its preparation method. The swine immunopotentiator belongs to the technical field of feed additives. The swine immunopotentiator provided by the invention comprises the following components: by weight, 12-20 parts of yeast beta-glucan, 10-20 parts of a poplar flower extract product, 15-20 parts of a bamboo shoot shell extract product, 15-25 parts of a bacillus subtilis bacterial powder for producing phytase, 6-10 parts of propolis, 2-5 parts of gamma-aminobutyric acid, 1-4 parts of mannan oligosaccharide, and 3-5 parts of chlorogenic acid. Through scientific compatibility and by enhancing specific and nonspecific immunity in the orgamism and regulating and controlling gut immunity and development, immune level of the organism is raised. Thus, swine health degree is raised, utilization rate of a feed is improved, and rapid growth of pigs is promoted. The swine immunopotentiator is a green safe high-efficiency swine immunopotentiator.
