The invention provides a
neglect-proof drinking immunization tablet for
infectious bursal disease (IBD), which comprises an
antigen for IBD, a heat-resistant protective agent and an effervescent material, wherein the
antigen for IBD and the heat-resistant protective agent are mixed to prepare a heat-resistant
antigen freeze-dried particle, and then, the particle and the effervescent material are evenly mixed and pressed to obtain the
neglect-proof drinking immunization tablet. Because a color indicator is added into the effervescent material, by checking whether chicken
beak tips are dyed or not, the chicken which does not drink water can be easily found, and the chicken can drink water, thereby effectively avoiding the occurrence of an immunization
neglect phenomenon; and a
metal chelator, an immune
potentiator and a heat-resistant protective agent are added, and a tablet is prepared, thus the vaccine is convenient to transport and store, and the storage time exceeds 24 months. When in use, the vaccine tablet provided by the invention only needs to be put into a proper amount of water for chicken flocks to drink to enable the chicken flocks to be immunized, thereby realizing the effective immunization of IBD of the chicken flocks, ensuring the immunization uniformity, preventing the immunization neglect, and enhancing the vaccine immunization effect. The tablet provided by the invention is most suitable for medium-and-large-sized chicken farms.
