Problems solved by technology

[0003] Since there are no effective vaccines and drugs at this stage, once an epidemic occurs in a pig farm, the teeth will be pulled out if the pig farm is mild, and all will be culled if it is severe.

Abstract

The invention discloses a method for preventing African swine fever. The method comprises the following steps: (1) performing feeding in a rearing period: adding a mixed feed additive of which the main components are plant polysaccharide and a microecological preparation into pig feed, and feeding domestic pigs by taking a pig feed added with the mixed feed additive as daily ration; (2) feeding water: adding a microecological preparation into drinking water of the domestic pigs to prepare probiotic water with a concentration of 0.05-0.15% as daily drinking water of the domestic pigs; and (3) performing biological disinfection of the environment: preparing a biological disinfectant with a concentration of 0.02-0.1% by adopting a microecological preparation in an epidemic situation period and the whole rearing period, and spraying the biological disinfectant to a pig house and a factory for disinfection once a day. According to the invention, plant polysaccharide and probiotics are takenorally, drinking water and feeding environment biological disinfection is combined, animal intestines are regulated and controlled, and a three-dimensional ecological prevention and control system iscreated through improvement from intestinal tract micro-ecology to environment macro-ecology, so that the immunity and disease resistance of pigs are improved, and successful rearing in a common-scale pig farm is achieved.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular relates to a method for preventing African swine fever. Background technique [0002] African Swine Fever ((African Swine Fever, ASF)) is an acute, febrile, highly contagious and devastating infectious disease caused by African swine fever virus (ASFV), with almost 100% infection morbidity and mortality. [0003] Since there are no effective vaccines and medicines at this stage, once an epidemic occurs in a pig farm, the teeth will be pulled out if it is mild, and all will be culled if it is serious. In the context of the raging ASFV and the lack of effective prevention and control vaccines and drugs, it is of great significance to study ASF prevention and control technology based on traditional Chinese medicine and probiotics. Contents of the invention [0004] The purpose of the present invention is to provide a method for preventing African swine fever, by eating feed...
