Will mixed breeding of chickens, ducks and geese with pigs lead to the occurrence of highly pathogenic avian influenza
Poultry should not be mixed with pigs, because poultry influenza virus can be infected to pigs, while human influenza virus can also be transmitted to pigs. Because influenza virus has eight different nucleic acid fragments, when these two different virions infect a cell together, the nucleic acid fragments will be recombined and arranged to produce new influenza virions. This new type of influenza virion can often form a great epidemic to human beings, and cause great harm.
In addition, chickens should not be mixed with ducks, geese and other waterfowl, so the carrying rate of various subtypes of influenza virus in waterfowl is very high, and some of them do not show any clinical symptoms. After the virus in its feces infects chickens, it can cause the occurrence and epidemic of avian influenza, resulting in serious economic losses.
