Evaluating the Effect of Methanolic Extract of <i>Astragalus effusus</i> Plant on the Hatching of Eggs of <i>Haemonchus</i> Species <i>In Vitro</i>

Introduction: Internal parasites, especially nematode infections of the digestive tract (e.g., different species Haemonchus), have always been associated with economic losses in sheep production systems tropical regions. Therefore, implementation environmentally benign treatment alternatives is essential for integrated parasite control programs. The current study aimed to evaluate effect methanolic extract Astragalus effusus plant on hatching eggs Haemonchus laboratory conditions. Methods: This was conducted between 2021 and 2022 Tabriz, Iran. were extracted from experimentally infected exposed concentrations (10, 20, 40, 80, 160 mg/mL) under percentage recorded after repeating experiments five times, 50% 90% inhibitory (CL50 CL90) estimated through regression analysis. Results: Our results demonstrated A. conditions satisfactory results. 1% 8% (10-80 significant, 0.5% dimethyl sulfate considered as negative group (χ2=0.024, P&lt;0.05). Likewise, a concentration 16% (160 similar albendazole (positive control). Conclusion: In conditions, effective preventing species, which important guide further studies other compounds this all stages life because widely adapted geographical climatic
