Why livestock and poultry are not suitable for polyculture

Recently when it comes to the prevention and treatment of highly pathogenic avian influenza, many experts have mentioned that poultry farms should not be polyculture such as chickens, ducks or geese, nor should they be polycultured with pigs. The term "non-mixed farming" refers to the same poultry farm. Do not breed several types of birds or pigs at the same time. First of all, because polyculture of poultry is not conducive to arranging a disease prevention plan for poultry farms; secondly, some epidemics have mainly occurred only in some kinds of poultry, but under certain conditions other poultry can also be infected, such as Newcastle disease of chickens, and sometimes Ducks, geese, pigeons and other poultry can also occur. In addition, some diseases are afflicted by many birds. Once a certain poultry first catches the disease, it will quickly cause the occurrence of other poultry diseases, such as fowl cholera, colibacillosis and bird flu. Bird flu virus can infect chickens, ducks, geese and other poultry and wild birds. In particular, waterfowls are easily infected with the bird flu virus when they come in contact with outside sources of water, and some do not show any clinical symptoms. Therefore, the rate of carrying out influenza viruses of various subtypes in waterfowls is high, and excreted feces contain large amounts of viruses. It can infect chickens or other poultry, causing the occurrence and prevalence of bird flu, which can lead to serious economic losses. Therefore, chicken farms are even less suitable for raising ducks, geese and other water birds. Why shouldn't poultry be mixed with pigs? Because a research report shows that poultry's flu virus can infect pigs, human's flu virus can also be transmitted to pigs, and pig's flu virus can be transmitted to humans as well as to chickens. Pigs may be found in humans, pigs, and poultry. Influenza virus plays a role as a mixer or intermediary. Of particular note is that since the influenza virus has 8 different nucleic acid fragments, when the two different virus particles co-infect the same cell of a certain animal (such as a pig), the nucleic acid fragments are recombined and arranged. Generate new influenza virus particles. Will this new type of influenza virus particles cause a major epidemic in humans and cause great harm? Although we do not yet have definitive proof that pigs play a role as mixers in the evolution of influenza viruses, we must be alert to this situation. Therefore, it is not appropriate for poultry farms to raise pigs at the same time.
