2005/2006年进行了为期13个月的纵向示范项目，以确定以社区为基础的战略性蠕虫控制方案在控制牛的胃肠道线虫和巨大片虫方面的有效性。在坦桑尼亚伊林加地区的Kilolo区随机选择了两个村庄，即一个CBWC村(Ilula-Masukanzi)和一个没有CBWC村(Kilolo-Luganga)。这两个村庄的动物都是在传统的管理制度下，使用村里的公共放牧区。在有CBWC的村庄，从该村10个养殖场选择60头6-18月龄的泽布牛，并标记耳朵，每月取样和编织。制定了一项战略性的《生物多样性公约》方案，村里的所有动物(有标记的和未标记的)每年四次用10%的阿苯达唑浸泡，每次10毫克/公斤，例如雨季中期(2月)、雨季结束(5月)、旱季中期(9月)和旱季后期/早期(12月)。在没有CBWC的村子里，从该村11个养殖场选择68头6-18月龄的泽布牛，并标记每月取样称重。没有CBWC的村庄的农民被允许继续他们的正常管理做法，包括驱虫治疗。在13个月的时间里，每月收集来自标记动物的粪便和血液样本以及来自公共放牧区的牧场样本。结果表明，CBWC战略方案在减少粪卵数量(FEC)和粪便中通过片吸虫卵的动物比例方面非常有效。与无CBWC的村庄相比，战略性CBWC显著降低了动物的FEC(P<；0.01)。与没有使用CBWC的村子里的动物相比，每年四次CBWC的战略性处理显著降低了粪便中通过片吸虫卵的动物的比例(P<；0.05)。从试验开始到试验结束，有CBWC的村庄的动物比没有CBWC的村庄的动物平均每年增重13.9公斤(P<；0.05)。结论：CBWC战略计划在降低FEC、减少粪便中通过片吸虫卵的动物比例和改善动物体重方面是非常有效的。
A longitudinal demonstration project was carried out in 2005/2006 for thirteen months to determine the effectiveness of a strategic community-based worm control (CBWC) programme in the control of gastrointestinal (GI) nematodes and Fasciola gigantica in cattle. Two villages namely, a CBWC village (Ilula-Masukanzi) and a village without CBWC (Kilolo-Luganga) were randomly selected in Kilolo district, Iringa region of Tanzania. Animals in both villages were under the traditional management system and used the village communal grazing area. At the village with CBWC, 60 zebu cattle (6-18 months old) from 10 farms in the village were selected and ear tagged for monthly sampling and weghing. A strategic CBWC programme was instituted whereby all animals in the village (tagged and non-tagged) were treated with albendazole 10% drench at 10 mg/kg four times a year e.g. middle of the rainy season (February), end of the rainy season (May), middle of the dry season (September) and late dry/early rainy season (December). In the village without CBWC, 68 zebu cattle (6-18 months old) from 11 farms in the village were selected and tagged for monthly sampling and weighing. Farmers in the village without CBWC were allowed to continue with their normal management practices including anthelmintic treatments. Faecal and blood samples from tagged animals and pasture samples from communal grazing areas were collected on monthly basis for 13 months. Results showed that strategic CBWC programme was highly effective in reducing faecal egg counts (FEC) and the proportion of animals passing Fasciola eggs in faeces. The strategic CBWC significantly reduced FEC of animals by an average of 60% compared to animals at the village without CBWC (P < 0.01). Four strategic CBWC treatments per year significantly reduced the proportion of animals passing Fasciola eggs in faeces by an average of 82.5% compared to animals at the village without CBWC (P < 0.05). From commencement to the end of the trial, animals at the village with CBWC significantly outgained animals at the village without CBWC by an average of 13.9 kg per year (P < .05). It is concluded that strategic CBWC programme was highly effective in reducing FEC, reducing the proportion of animals passing Fasciola eggs in faeces and improved weight gain in animals.
