The Puriifed Propagation Field Investigation And Analysis Of Swine Pseudorabies Of Scale Pig Breeding Farm In Nanchang

Recently, with the vigorous developing in pig industry, the pig pseudo rabiesoccurrence frequency are increased rapidly, bringing a huge economic losses. Take tests-discard-monitoring-purification, and immune, comprehensive measures such asquarantine, disinfection and isolation, in accordance with the "disease census (group ofgroup of qing dynasty) to infection-target group monitoring (build without infectiongroup)-continuous monitoring no infection group (keep)-disease cleansing" theimplementation process, in2010，Under the technical guidance of the programs andprovincial animal disease control center, The serologic identification test have been appliedto19pig farm in Nanchang,1900blood samples collected, the average positive rate was11.421%,and the result show that the purification work for pseudo rabies virus is urgentlyneeded.This paper select a period between2011-2012, taking eight secondary pig farm usingpig pseudo rabies gene identification ELISA methods serological antibody test, to serve asthe cornerstone for the following purification.The result shows that, through theimplementation of a series of control and decontamination measures, the infection rates ofbreeding pig farm are decreased significantly. and shows that the breeding herd pseudorabies field virus infection positive rate is less than10%.
