Abstract:In this experiment, group experiments on HC and FMD were carried out on freerange fernhemp pigs in farming and pastoral villages in Diebu, Lintan, Hezuo and other counties and cities. The ELISA method was used to regularly detect the antibody titer of the immune effect of pigs at different stages, to initially explore and propose a new programmed immunization model adapted to the epidemic of freeranging fern and hemp pigs in the plateau, to ensure that effective prevention can be achieved in the severe animal epidemic situation, to establish a solid immune barrier, and to strive for stable production and supply of highaltitude pigs.
