This study was undertaken to examine the in vivo effect of <em>Parkia biglobosa</em> and <em>Pterocarpus erinaceus</em> on the viability and fertility of adult <em>Haemonchus contortus</em> worms in sheep. Fifteen Djallonke sheep, 4 to 5 months old, were divided into three experimental lots. The control lot received no treatment. Two lots were treated with 3.2 g/kg PV of plant powder. <em>P. biglobosa</em> significantly reduced egg excretion compared to the control (p &lt; 0.05). Both plants significantly (p &lt; 0.05) reduced the number of adult worms and the number of eggs per female worm. Numbers of adult worms and eggs per female worm were 330.00 ± 112.84 and 332.0 ± 191.9 in the control lot, 17.50 ± 10.41 and 176.0 ± 96.1 in the lot treated with <em>P. biglobosa</em> and 86.25 ± 53.13 and 146.8 ± 90.6 in the lot treated with <em>P. erinaceus</em>, respectively. This study showed that <em>P. biglobosa</em> and <em>P. erinaceus</em> exerted anthelmintic activity in vivo on adult <em>H. contortus</em> worms. Further investigations are needed to evaluate the toxicity of these plants and to understand their metabolism in the digestive tract of animals.</p> 2022-10-22T00:00:00+01:00 Copyright (c) 2022 Vidjinnangni Fifamè Grâce Nadège Dedehou, Irvine Yèïnou Minaflinou Sacca Sidi, Fréjus Tanguy Ablo Zinsou, Pascal Abiodoun Olounladé, Sylvie Mawulé Hounzangbé-Adoté
