Functional preparation for preventing and treating porcine reproductive and respiratory syndrome and preparation method thereof

Abstract

The invention provides a functional preparation for preventing and treating the porcine reproductive and respiratory syndrome. The functional preparation is prepared from the following main raw materials in parts by weight: 30-70 parts of glycerol monolaurate, 5-20 parts of butyrin, 10-40 parts of astragalus membranaceus and 5-25 parts of liquorice. The preparation method comprises the following steps that (a) the astragalus membranaceus and the liquorice are crushed and then sieved with a 40-mesh grading sieve; (b) the glycerol monolaurate and the tributyrin are sieved with a 20-mesh grading sieve; (c) the astragalus membranaceus and the liquorice are mixed according to a formula to obtain a mixture A; (d) the glycerol monolaurate and the tributyrin are mixed according to the formula to obtain a mixture B; and (e) the mixture A and the mixture B are mixed. According to the functional preparation and the preparation method thereof, a porcine reproductive and respiratory syndrome virus cyst membrane is enabled to lose the infection ability by utilizing the destruction mechanism of the glycerol monolaurate on the porcine reproductive and respiratory syndrome virus cyst membrane, the energy source is provided for intestinal epithelial cells by utilizing the butyrin, and the detoxification effect is achieved by utilizing the cooperation of the astragalus membranaceus and the liquorice; and the functional preparation is clear in mechanism, stable in component, remarkable in curative effect, small in side effect and convenient to use.

Description

technical field [0001] The invention belongs to the field of feed additives, and more specifically relates to a functional preparation for preventing and treating pig blue-ear disease and a preparation method thereof. Background technique [0002] Pig blue-ear disease, also known as "porcine reproductive and respiratory syndrome", is a highly contagious infectious disease caused by pig blue-ear disease virus. It is highly contagious and lethal. It is listed as a second-class infectious disease in my country . Pigs of different breeds, ages and uses can be infected with the disease, and piglets within one month of age are the most susceptible. It is characterized in that: the newborn piglets mainly show dyspnea, movement disorders and paresis. It is easy to cause abortion, stillbirth, mummified fetus, lack of milk, repeated infertility and other phenomena in sows. The disease can occur all year round and is one of the main diseases that endanger the pig industry. [0003] H...

AI Technical Summary

Problems solved by technology

[0003] However, the disease is difficult to prevent and control because of the diversity and variability of strains, the current lack of universal vaccines, the strong ability of vertical transmission and persistent infection, and can even be transmitted through aerosols

[0004] At present, some antibiotics or antiviral drug injections are mainly used for prevention and treatment in pig production. Commonly used injections include streptomycin, penicillin, sulfadiazine, ribavirin, Radix Radix, and Folium chinensis, and some vaccines are used for prevention. , but on the whole, these drugs have a certain effect on PRRS, but the effect is not ideal, and some have serious side effects and are inconvenient to use
