摘　　要：为了分析提升生物安全措施对猪场主要疫病防控及生产性能的影响,在宁化县某猪场进行生物安全防控措施提升,在提升前后随机采集血清、病料样品进行抗体和病原核酸检测及生产性能记录。结果表明,猪场提升生物安全措施后猪瘟、猪繁殖与呼吸综合征、口蹄疫等主要疫病免疫抗体合格率提高4.0%~10.8%(P<0.05);病原种类减少2种,病原核酸阳性率下降16.8%~30.4%不等(P<0.05),无共同感染病例;母猪配种受胎率提高6.8%、年产胎次提高0.25胎、平均每头母猪胎次产健仔数增加2.91头、平均断乳窝重提高9.8 kg,仔猪发病率和病死率分别下降8.2%和4.1%。可见,猪场提升生物安全措施对主要疫病防控有显著效果,同时提高了猪群的生产性能。In order to analyze the impact of improving biosafety measures on the prevention and control of major diseases and production performance in pig farms,a biosafety prevention and control measure was carried out in a pig farm in Ninghua county.Before and after the improvement,serum and disease material samples were randomly collected for antibody and pathogen nucleic acid testing,as well as production performance recording.The results showed that after the improvement of biosafety measures in pig farms,the qualified rate of immune antibodies for major diseases such as swine fever,porcine reproductive and respiratory syndrome,and foot-and-mouth disease increased by 4.0%to 10.8%(P<0.05),the number of pathogenic species decreased by 2,and the positive rate of pathogenic nucleic acid decreased by 16.8%~30.4%(P<0.05),with no cases of co-infection;The breeding and conception rate of sows increased by 6.8%,the annual parity increased by 0.25,the average number of healthy piglets per sow parity increased by 2.91,the average weaning litter weight increased by 9.8 kg,and the incidence rate and mortality of piglets decreased by 8.2%and 4.1%respectively.It can be seen that improving biosafety measures in pig farms has a significant effect on the prevention and control of major diseases,while also improving the production performance of pig herds.
