高寒阴湿区牛羊寄生虫病防控技术模式研究

Study on the Prevention and Control Mode of Parasitic Diseases of Cattle and Sheep in High Cold Damp Area

本研究旨在解决严重危害高寒阴湿区牛羊养殖的寄生虫病。通过流行病学调查及检测筛选出危害高寒阴湿地区牛羊养殖的主要寄生虫病种,利用高效广谱药物适时驱虫的同时,改善饲养管理方式,推迟放牧时间,形成了“514”防控技术模式。通过“514”防控技术的推广应用,羊在春季的发病率从25%~30%下降到1.18%,病死率从40%~45%下降到7.69%;牛皮蝇蛆病感染率从30%下降到1.08%。在高寒阴湿区推广应用牛羊寄生虫病“514”综合防控模式可有效预防和控制牛羊寄生虫病的发病率和死亡率,经济效益和社会效益十分显著。

The study aims to solve the parasitic disease that seriously harms cattle and sheep breeding in alpine and humid areas.Through epidemiological investigation and detection,the main parasitic diseases harmful to cattle and sheep breeding in alpine and humid areas were screened out while using the effective broad-spectrum drugs to timely de-worming.Meanwhile,the breeding management methods were improved and the grazing time was postponed,forming a“514”prevention and control technology model.Through the popularization and application of“514”prevention and control technology,the incidence rate of sheep decreased from 25%~30%to 1.18%in spring and the fatality rate decreased from 40%~45%to 7.69%and infection rate of hypodermosis dropped from 30%to 1.08%.The comprehensive prevention and control model of“514”could effectively prevent and control the morbidity and mortality of parasitic diseases of cattle and sheep in alpine and humid areas,which could make economic and social benefits very significant.
