How to use non-nutritive feed additive to control Avian Influenza?

Avian Influenza: The full name, Avian Influenza (AI), is an animal infectious disease caused by a virus and usually only infects birds. At present, it has caused serious losses and low production capacity in the industry of chicken, ducks, geese, ostriches, etc. It is no exaggeration to say that Avian influenza is the biggest killer of the poultry industry.

The source of infection of Avian influenza is not only chickens, ducks, and geese as carriers, but also carriers for migratory birds and wild birds. It even infects pigs, horses, whales, and humans. Therefore, once viral infectious diseases of a non-single host spread in a regional area, it is very difficult to completely clear the virus from this area after years of observation and research.

Avian influenza virus is from the Orthomyxoviridae of RNA virus. In its character, the RNA virus is easy to mutate. Therefore, the strategy of using vaccines to prevent and control Avian influenza will be greatly difficult. When using vaccines for Avian influenza in some countries, vaccines must often change the serotype of the virus to correspond to the constantly mutating virus, but the effect to prevent and control Avian influenza is still limited due to changing the vaccine passively and ineffectively to dealing with the outbreak of epidemic viral disease. The animals get vaccinated 2 to 5 times per year on some farms, but it still causes losses due to the outbreak of Avian influenza. This is not because of the vaccine but the relationship between the animal immune system because the immune system has a high degree of targeting and specificity for virus prevention and control. Therefore, once the virus mutates more than 3 to 5 times, the protection of the vaccine will be reduced, or even unable to protect.

The use of non-nutritive feed additive, ImmuniVAP, provides another new solution for highly mutated viral infectious diseases, and can quickly induce mucosal immunity. The IgA antibody produced can neutralize the virus in the mucosa to greatly reduce the risk of virus infection. Furthermore, no matter how the virus mutates in the environment, ImmuniVAP can assist the immune system to produce corresponding target antibodies, which can neutralize the virus quickly and effectively.

Chickens are very sensitive animals and are easily affected by environmental changes (cold stress, heat stress, space stress, etc.). In the use of vaccines, disease outbreaks are often caused by flocks or adverse reactions to vaccines.

Three major effects to use ImmuniVAP:

(1) Make up the gap in vaccine protection due to reducing protection for virus mutation.

(2) Quickly produce antibodies and shorten the probability of infection due to the use of vaccines.

(3) Alleviate adverse reactions due to vaccine use.
