目的 查明洞庭湖区牛群放牧行为的特点 ,为优化牛群血吸虫病化疗策略提供科学依据。方法 在洞庭湖区设 4个点分层观察距防洪大堤 5 km以内牛群的放牧时间、地点和方式 ,以及近 3年来化疗情况。结果 饲养户距堤 0 - 10 0 0 m、10 0 1- 2 0 0 0 m、2 0 0 1- 30 0 0 m、30 0 1- 40 0 0 m、40 0 1- 5 0 0 0 m 5层的牛群在外洲放牧的比例分别为 95 .35 %、78.0 5 %、10 .71%、0、0 ;放牧方式为敞放。5层平均化疗覆盖率分别为 85 .2 9%、5 6 .0 0 %、30 .13%、2 4.5 6 %、0。结论 洞庭湖区牛群在外洲放牧数量和时间与距堤远近有关 ,距堤越近 ,比例越大 ,距堤越远 ,比例越小 ,3km以外无牛在外洲放牧。
Objective To explore the pasturing characteristics of cattle so as to make suitable schistosomiasis chemotherapy strategies for cattle in Dongting Lake rigions.Methods Four pilots were selected in Dongting Lake regions.The pasturing time, place and pattern of cattle in the pilots were observed, and their treatment in recent 3 years were also investigated. Results The pasturing ratios outside embankment of cattle in the 5 layers of 0-1000 m,1001-2000 m,2001-3000 m,3001-4000 m and 4001-5000 m to the dike were 95.35%,78.05%,10.17%,0 and 0 respectively. The average chemotherapy coverage were 85.29%,56.00%,30.13%,24.56% and 0 respectively. Conclusion The pasturing time and the number of cattle outside embankment was negative relevant to their distance to the dike.No cattle were pastured outside embankment while their distance to the dike was more than 3 km.The cattle which pastured in the snail-ridden areas should be treated.
