Embodiment Construction

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] In the embodiment of the present invention, a kind of method that is specially used to prevent African swine fever comprises the following steps:

[0025] S1: Selection and purification of cultivation carrier

[0026] At this stage, the culture carrier is to select healthy and strong cats, dogs and sheep aged 3-10 months, sterilize the selected carrier, inject basic vaccines, and then raise them separately for use;

[0027] S2: Extraction of pathogens

[0028] Because the African swine fever antibody-generating factor is pr...

Abstract

The invention discloses a special method for preventing African swine fever. The special method comprises the following steps: 1, culturing a vector and carrying out purifying, 2, carrying out pathogen extracting, 3, rejuvenating a virus, 4, inoculating the vector with the virus and carrying out culturing, and 5, carrying out antibody generator extracting and manufacturing. According to the special method, the technical product is not a traditional Chinese medicine, is not a traditional Chinese medicine dispensation, is free of any chemical, is a purely-natural heated-up culture, is non-toxic and free of adverse reactions on pigs and nearby environments and is pollution-free; the technical product is high in safety to the pigs, a large dose is applied to newborn 3-day, 10-day, 15-day and 25-day suckling pigs, no abnormal condition is observed in 10 days, and no abnormal condition is observed for pregnant 5-110-day sows and other normal sows which are continuously applied with the technical product for five months; and two challenge experiments are carried out on pigs which use the technical product for 20-50 days and are artificially infected by an African swine fever virus, and the success rate is 100%.

Description

technical field [0001] The invention relates to the technical field of African swine fever prevention, in particular to a method specially used for preventing African swine fever. Background technique [0002] African swine fever (African swine fever, ASF) is an acute, febrile, highly contagious infectious disease of pigs caused by African swine fever virus infection. It is characterized by organ bleeding and high mortality. African swine fever originated in Africa and has been prevalent in East Africa for a long time in the past. According to the analysis of literature records, the African swine fever epidemic can be traced back to the early 20th century. [0003] The existing medicaments for preventing African swine fever virus are expensive to manufacture, and pigs have adverse reactions after use, the amount of inoculation is difficult to control, and incomplete inactivation of medicaments may lead to the secondary spread of African swine fever. Therefore, the present...
