Embodiment Construction

[0024] Specific embodiments of the present invention will be described in detail below. In order to avoid too many unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0025] Approximate language used in the following examples is for quantitative representations, indicating that certain variations in quantities are permissible without altering essential function. Accordingly, values ​​modified by language such as "about", "approximately" and the like are not limited to the exact value itself. In some embodiments, "about" means that the corrected value is allowed to vary within the range of plus or minus ten percent (10%), for example, "about 100" means any value between 90 and 110. Furthermore, in the expression "about the first value to the second value", both values ​​of the first value and the second value are corrected approximately at the same time. In some cases, the language of approximation may relate...

Abstract

The invention provides a preparation method of a microencapsulated oral vaccine for infectious serositis of ducks, and belongs to the technical field of veterinary biological products. The method comprises the steps of preparing, enriching and purifying of a vaccine preparing bacteria solution, inactivating, microcapsule coating and the like. The microencapsulated oral vaccine for the infectious serositis of the ducks can be used for prophylactic vaccination of the ducks by water drinking or feeding, and compared with a traditional injection immunization route, the microencapsulated oral vaccine is simpler and more convenient, saves time and labor, can effectively avoid occurrence of side reactions in injection sites, is conducive to improving of quality of meat, and has a good prospect oflarge-scale application.

Description

technical field [0001] The invention relates to the technical field of veterinary biological products, in particular to a preparation method of duck infectious serositis microencapsulated oral vaccine. Background technique [0002] Riemerella anatipestifer (RA) infection is a contagious disease of domestic ducks, geese, turkeys and other poultry and wild birds, also known as new duck disease, duck sepsis, duck disease syndrome, Duck septicemia and infectious serositis. Riemeria anatipestifer infection of geese was once known as goose flu or goose exudative sepsis. The disease takes the form of acute or chronic sepsis and is characterized by fibrinous pericarditis, perihepatitis, air sacculitis, caseous salpingitis, and meningitis. The disease is a major disease that endangers the duck industry all over the world. The disease causes huge economic losses due to the high mortality rate of sick ducks, emaciation, carcass elimination, quality decline, and disease treatment. ...
