Introduction：Take the experiment from “Simultaneous Test” and “Comparasion between after using PRCP and before using”. PRCP is found to assist the produce of immunoglobulin A, which will block PRRS virus out of the mucosa layer and neutralize virus. Consequently, a new test is conducted in a positive-IgG pig farm. Nowadays, PRRS virus exists in the surroundings. If no empty the pigsty, it is hard to eliminate the virus, which causes that the virus will infect hosts and that the IgG titer results are positive. With an index of the PRRS-IgG titer, we observe PRP will eliminate virus in vivo or not.
