First, cut off the transmission route is the key
There are two ways to transmit Avian Mycoplasma: horizontal and vertical.
1. Horizontal transmission Diseased poultry or infected poultry breathe and cough, discharge a large amount of mycoplasma with mucus, and infect healthy poultry through the air.
2. Vertical transmission The pathogen is transmitted by eggs infected with mycoplasma. At present, the prevalence of mycoplasma in poultry farms has not been effectively controlled, so the vertical propagation mode is more prominent in the prevalence of mycoplasma.
