Abstract

The effects of a prophylactic anthelmintic intervention on the productivity of village based sheep and goats was studied in an area of high trypanosomosis risk in The Gambia during 2 and 3 years, respectively. In total, 223 sheep and 385 goats from five villages were included. Allocation to treatment groups (treated-control) was randomised by village, based on age and sex. Three treatments per rainy season were applied with Fenbendazole (Panacur, Hoechst, 2.5%, 5 mg/kg). Mean nematode egg excretion per gram faeces (EPG) of the treated groups were significantly reduced by prophylactic anthelmintic treatment, indicating the efficiency of the treatment despite the risk of rapid reinfestation. Weight gain benefits of anthelmintic treatment were observed in all age categories (> 6 month) of sheep but not in goats. Kidding rates were significantly increased whilst the same positive trends were observed for other reproductive parameters (litter size, parturition interval) in both goats and sheep without reaching statistical significance. Birth weights of offspring born out of treated does and ewes were higher (P < 0.05) than those from the controls. In contrast, growth rates until 3 months of age were not influenced by the treatment s...Continue Reading

Anthelmintics

Anthelmintics or antihelminthics are a group of antiparasitic drugs that expel parasitic worms (helminths) and other internal parasites from the body by either stunning or killing them and without causing significant damage to the host. Discover the latest research on anthelmintics here.
