Feed additive for improving disease resistance of escherichia coli

Abstract

The invention relates to a feed additive for improving disease resistance of escherichia coli. The feed additive is prepared from 18-24 parts of burdock, 15-20 parts of herba patriniae, 15-20 parts of cordate houttuynia, 12-16 parts of folium isatidis, 12-16 parts of radix sophorae flavescentis, 8-12 parts of submerged root rhubarb, and 3-5 parts of gypsum as raw materials. The feed additive disclosed by the invention plays the roles of resisting viruses, clearing heat, diminishing inflammation, detoxifying, invigorating stomach, dehumidifying, breaking through intestines and regulating the flow of vital energy, and also can prevent and treat colibacillosis. Therefore, the recovery rate and the daily gain of piglets are improved, and the mortality of the piglets is reduced.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a feed additive for improving pig colibacillosis resistance. Background technique [0002] At present, yellow and white scours of piglets occur all over the world. In countries with more developed pig farming, such as the United States, the incidence of yellow and white scours of piglets is about 20%, and the mortality rate is 15.5%. According to statistics, the incidence of yellow scour of piglets in my country in 2001-2003 was 104,511, and the direct economic loss reached 50 million yuan. Some data show that in some large-scale pig farms in East China, the average incidence rate of yellow and white scours of piglets is 29.0%, and the average mortality rate is 20.4%. If piglet yellow and white scour is co-infected with other pig diseases, the mortality rate of piglets can reach more than 60%. Yellow dysentery occurs mostly in suckling piglets less than 7 days old. The dis...

Problems solved by technology

[0003] There are many methods to prevent and treat porcine colibacillosis, such as injecting vaccines to sows in the late pregnancy, so that newborn piglets can obtain immunity through maternal antibodies, research and use of porcine colibacillus autoimmune vaccines, etc. There are quite a lot of serotypes, so the control effect is not ideal

At present, the most clinically used antibacterial drugs are used for treatment, but because Escherichia coli is more likely to produce drug resistance, especially the widespread use of antimicrobial drugs recently, the drug-resistant strains continue to increase

In addition, Western medicine mainly uses antibacterial drugs to treat porcine colibacillosis. Although many pathogenic E. coli can be inhibited or killed in this way, there are a large number of non-pathogenic bacteria in the intestinal tract of the body in addition to pathogenic E. coli. , they play an important role in the normal metabolism of the body. When antibacterial drugs are used blindly, they will inhibit or kill the non-pathogenic bacteria in the intestinal tract of the body and destroy their composition, which will seriously affect the digestive function of the body, thus lead to a series of problems
