Problems solved by technology

However, people use vaccines to immunize duck plague, and the early effect is better, but multiple vaccinations are required, the operation is troublesome, the cost is high, and it is easy to cause stress reactions in livestock and poultry, and the vaccines have strict requirements for storage conditions. Refrigerate at low temperature, and it will fail after a period of time at room temperature

Abstract

The invention discloses a composition for resisting duck plague, freeze-dried powder, and a preparation method and use of the freeze-dried powder, and belongs to the technical field of veterinary feed additives. The composition comprises, by weight, 90-100 parts of a duck plague-resistant yolk antibody and 0.5-2 parts of a duck plague-resistant transfer factor. The freeze-dried powder comprises, by weight, 95-97 parts of the duck plague-resistant yolk antibody, 1-2 parts of the duck plague-resistant transfer factor, 0.2-0.3 parts of an inactivator, 0.01-0.02 parts of an antiseptic and 2.05-3.6 parts of a heat-resistant freeze-dried protective agent, and has the advantages of low preservation conditions, long preservation time, high antibody titer and good biological activity. Through combined use of the duck plague-resistant yolk antibody and the duck plague-resistant transfer factor, the freeze-dried powder has effects of preventing and treating duck plague, improves duck immunity and survival rate, is convenient for use and has a low cost.

Description

technical field [0001] The invention specifically relates to an anti-duck plague composition for a feed additive, and an anti-duck plague freeze-dried powder, and also relates to a preparation method and application of the freeze-dried powder, belonging to the technical field of animal feed additives. Background technique [0002] Duck plape, also known as duck virus enteritis (DVE), is an acute, febrile, septic infectious disease of ducks, geese and other Anseriformes. The disease is characterized by widespread prevalence, rapid spread, and high morbidity and mortality. As early as 1923, Baudet first discovered the disease in the Netherlands, until 1940, Bos first proposed the name of duck plague, and confirmed that it was a new virus disease different from chicken plague. Afterwards, there were reports of the occurrence of this disease in various countries in Europe and the United States. The official report of the prevalence of duck plague in my country was first propos...
