| Summary : | In a preliminary experiment the anthelmintic efficacy of nine plants in goats experimentally infected with Haemonchus contortus was evaluated.the study was conducted in 55 male goats approximately eight months of age.All were effectively drenched and then infected with approximately 100000 g larvae of H. contortus. Twenty five days post infection, the plants were administered orally as a single dose in the form of a juice, using a gastroesophageal tube. The nine plants tested were ineffective in reducing number of adult H. contortus. Those that showed the best performance were A.squamosa and M. charantia. In a further experiment these plants were selected for testing in 40 male castrated goals approximately eight months of age,naturally infected with gastrointestinal nematodes. A. squamosa given us 1g/kg for four consecutive days eliminated 51.90 % of the adult population of oesophagostomum columbianum, but was ineffective in eliminating H contortus, Trichostrongylus colubriformis and Strongyloides papillosus. Momordica charantia administered us 2g/Kg for four consecutive days was innefective in reducing the population of adult parasites. These results, allow us to conclude that the plants tested should not be used as the single medication for the control of gastrointestinal nematodes in goats. |
