Oil emulsion vaccine for broilers and preparation method thereof

Abstract

The invention discloses an oil emulsion vaccine for broilers and a preparation method thereof. The oil emulsion vaccine comprises a water phase and an oil phase, wherein the water phase contains concentrated and inactivated ND (newcastle disease) and H9 AI (avian influenza) venom and Tween-80; the oil phase contains an oil adjuvant formed by white oil, Span-80 and aluminium stearate; the volume ratio of the water phase to the oil phase is (1:1.6) to (1:2); and the kinematic viscosity (40 DEG C) of the selected white oil is 4-8mm<2> / s. The oil emulsion vaccine has the characteristics of easiness in absorption, quick effect and high level of the generated antibodies, is suitable for growth of the broilers, can effectively increase the immune levels of the broilers, can effectively protect the broilers from being invaded by ND and H9 AI viruses and avoids ND and H9 AI in the immune phase.

Description

technical field

[0001] The invention relates to an oil emulsion vaccine suitable for broilers and a preparation method thereof, especially a kind of chicken Newcastle disease and H 9 Subtype bird flu vaccine and preparation method thereof. Background technique

[0002] With the rapid development of the poultry farming industry, the occurrence of diseases also tends to be complicated. In order to pursue good production performance in modern broiler farming, there are more and more vaccines for chicken disease prevention, and more and more veterinary drugs to control chicken diseases, but there are still more and more chicken diseases. The characteristics of the disease of broiler chickens are that the mortality rate of broiler chickens is high. Once the disease occurs, the chickens will continue to die every day, and the course of the disease will last for a long time. Due to the unevenness of the breeding facilities and management levels, most diseases show obvious regional...
