A Constructive Plan for Rapid Dual Negative and Stable Growth of Porcine Reproductive and Respiratory Syndrome (PRRS) in Group Pig Farms
Abstract：To achieve rapid elimination of Porcine Reproductive and Respiratory Syndrome (PRRS) in group pig farms (virus nucleic acid and antibody dual negativity within 3-5 months), this plan aims to significantly shorten the 'persistent infection period' of the pig population and accelerate entry into the clearance phase, thereby achieving negative conversion of PRRS virus nucleic acid (detected in samples such as tonsils and lymph nodes). Studies show that after adopting this plan, the antibody levels of PRRS virus exhibit a gradual or rapid decline trend. The core mechanism of the plan lies in completing two purification goals: antigen and antibody. This is entirely dependent on the rapid activation of the pig's cellular immune function and the timely presentation of lymphatic clearance effects, with relatively low association with humoral immunity. This plan provides a replicable path for PRRS elimination in large-scale pig farms.
