干旱区规模化肉羊场布鲁氏菌病综合防控技术集成与应用研究——以甘肃省瓜州县肉羊布病防控实践为例
Integration and application of comprehensive prevention and control technology for Brucellosis in large-scale meat sheep farms in arid areas:
目的 评估甘肃省瓜州县肉羊布鲁氏菌病综合防控技术的应用效果,为干旱区动物疫病防控提供技术范式。 方法 以甘肃省瓜州县13个农业乡镇的规模化肉羊养殖场及关联散养户为研究对象,改良疫苗免疫程序、草场科学轮牧制度,集成“免疫净化-智能监测-生态防控”技术体系,覆盖种羊健康认证、调运监管、无害化处理等关键环节。 结果 技术体系应用后,肉羊布病个体阳性率从2.31%降至0.48%,群体净化率达98.6%;跨省调入检疫率提升至98.6%,人间病例年发生率从17例降至2例;草场植被盖度提高28%,无害化处理率从83%升至98%;累计产生综合效益5 826万元,投入产出比达1:4.3。 结论 “免疫-追溯-生态”三位一体防控体系显著降低布病传播风险,实现畜间净化目标,具有显著的社会经济效益。
Objectives The effects of applying comprehensive prevention and control technology for Brucellosis in meat sheep in Guazhou County, Gansu Province were evaluated to provide a technical paradigm for the prevention and control of animal diseases in arid areas. Methods Large-scale meat sheep farms and associated free range households in 13 agricultural townships in Guazhou County, Gansu Province were used to optimize protocol of vaccine immunization and implement a scientific management for pasture rotation. The technology system of "immune purification-intelligent monitoring-ecological prevention and control" was integrated to cover critical processes including breeding stock certification, transportation supervision, and harmless disposal. Results The individual positive rate of Brucellosis in meat sheep decreased from 2.31% to 0.48% after the implementation of the technology system, with a herd purification rate of 98.6%. Cross-provincial quarantine compliance increased to 98.6%, and annual human cases dropped from 17 to 2. The vegetation coverage of grassland increased by 28%, and the efficiency of harmless disposal rose from 83% to 98%. The accumulated comprehensive benefits reached 58.26 million CNY, with an input-output ratio of 1:4.3. Conclusions The three in one prevention and control system of 'immunity-traceability-ecology' significantly reduced the risk of Brucellosis transmission, achieved the goal of livestock purification, with significant social and economic benefits.
