某规模化猪场伪狂犬病的净化及经济效益分析
Elimination and economic benefit analysis of pseudorabies in a large-scale pig farm
摘要
Abstract
This study was to explore elimination of pseudorabies(PR)through the"detection-isolation/elimination-immunization"ap-proach in a large-scale parent-raising pig farm.Serum samples were collected from all boars,sows,and gilts,as well as a proportion of suckling piglets and nursery pigs.According to the results of the antibody detection,pigs with negative PRV-gE antibodies were isolated,while PRV-gE antibody-positive pigs and close contacts were eliminated.The immunization schedules were optimized for different pig groups with the objective of strengthening the vaccination of prenatal sows,newborn piglets,and nursery pigs.Furthermore,a series of measures were implemented to enhance the management of replacement pigs,including the strict implementation of the"all in,all out"principle,the timely elimination of sick pigs,and the enhanced disinfection of personnel,materials,and the environment.In accordance with the aforemen-tioned measures,PRV antibody testing was conducted every six months.The results showed a gradual increase in gB antibody seroconversion and a gradual decrease in gE antibody seroconversion as a result of the elimination process.Two years later,the gB antibody positivity rate of both the sows and gilts reached over 97％,while no further gE-positive pigs were detected in all pig herds,indicating that the farm had met the PR elimination standard.The statistical analysis revealed that,following the PR elimination,the PSY of the farm increased by 4.96,and the average annual income per sow increased by 1 636 yuan.This case study illustrated that the elimination of PR in large-scale pig farms could be achieved through the application of scientific elimination techniques and strict biosafety measures,which would improve the econom-ic income of pig farms.关键词
