| Popis: | A study was conducted to investigate the in-vitro and in vivo anthelmintic effects of crude methanol extracts of Azadirachta indica, Vernonia amygdalina, Nicotiana tabacum, Moringa oleifera, Croton macrostachyus, and Hagenia abyssinica against gastrointestinal nematodes of goats. The plants were collected from East Hararghe Zone during November 2017 to March 2018. Leaves from each plant species were separately collected, dried, ground, and crude methanol soluble was extracted. Three graded concentration of crude extract of 100mg/ml, 50mg/ml and 25mg/ml were prepared and evaluated for in vitro anthelmintic effects using standard techniques of larval development assay, larvae inhibition and egg hatch tests. For the egg hatch test, the wells containing about 100 eggs/ml were incubated at 27°C for 48 hours and evaluated based on the characteristics such as dead, embryonated, or hatched egg to L1. Similar egg concentrations were used for larval development assays and exposed to various concentrations of the plant extracts to evaluate the development of eggs to infective larvae (L3) over a period of six to seven days. For the larvae inhibition test, approximately 100 larvae were placed into test tubes containing plant extracts. The results were evaluated by adding a drop of warm water and counting of active and dead larvae at an interval of three hours, for a total period of twelve hours. For the in vivo trial, 1g/kg of the crude extract of the plants were prepared and administered via oral drenching.
