[0024] Preparation of virus seeds for production: NDV La Sota strain and IBV M 41 Strain viruses were diluted appropriately, inoculated with SPF chicken embryos, incubated, and harvested; preparation of virus liquid for seedlings: NDV La Sota strain and IBV M 41 Strain viruses were diluted appropriately, respectively inoculated with susceptible chicken embryos, and incubated; the live virus seeds were collected, respectively concentrated, inactivated, and NDV La Sota virus strain 17% and IBV M were used for seedling preparation. 41 The water phase was made by adding Tween-802% to 17% of the virus strain liquid. The oil phase was made from 60% white oil, 2% Siben-804%, and 2% aluminum stearate, and the ratio of the water phase to the oil phase was 1:2.5 Emulsify together; pack, label, pack, store.

Abstract

The invention relates to a method to prepare a combined inactive vaccine of newcastle disease and infectious bronchitis vaccine for chicks. The invention is characterized in that: firstly, concentrate and inactivate the NDVLaSota virus strains (10 per cent to 22 per cent weight ratio) and IBVM41 virus strains (10 per cent to 22 per cent weight ratio) respectively; and then add white oil and immune additives including tween, span and stearic acid to prepare the combined vaccine.

Description

Technical field: [0001] The invention relates to a biological agent for poultry, which is a preparation method of a dual inactivated vaccine of Newcastle disease and infectious bronchitis. Background technique: [0002] Prevention and control of infectious diseases is of great significance to the modern poultry industry. At present, the commonly used methods are mainly to strengthen sanitation and disinfection, but these alone cannot make the intensive large-scale production of the modern poultry industry resist the spread of infectious diseases, and it is common to cause great losses to the poultry industry. Facts have proved that the most important means of controlling infectious diseases in the poultry industry should be prevention, and vaccination is considered to be the most effective measure. [0003] Vaccines are autoimmune preparations made from pathogenic microorganisms (such as bacteria, rickettsia, viruses, etc.) and their metabolites, which are artificially atte...
