Effect of Artemisia absinthium and Malva sylvestris on Antioxidant Parameters and Abomasal Histopathology in Lambs Experimentally Infected with Haemonchus contortus

This study evaluated the effect of Artemisia absinthium and Malva sylvestris on antioxidant response histopathological changes in abomasa Haemonchus contortus infected lambs. Twenty-four lambs were divided into four groups: unsupplemented (UNS), supplemented with A. (ART), M. (MAL), both plants (ARTMAL). Lambs orally approximately 5000 third-stage (L3) larvae H. contortus. The experiment was conducted for 75 d (days), all animals then slaughtered, abomasal tissues examined parameters histopathology. concentration malondialdehyde mucosa lower ARTMAL (p < 0.05), total capacity higher MAL than UNS. Increased mucus production observed ARTMAL. number mast cells UNS ART significantly 0.01 p 0.05).
