    Abstract:
    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.
