Histopathological Effects of Albizia lebbeck Seeds Extract on Cecum Tissues of Broilers Infested Experimentally by Eimeria tenella

The study was aimed to investigate the pathological of cecum broiler chickens infected and treated by ethanolic Seed Extract of Albizia lebbeck. Sixty (Ross,310) broiler chicks were divided into 6 equal groups (10 birds / each), at age 17th day. A, control negative, B, control positive, C treated Amprolium1g/L in drinking water, and D, E, F (infected and treated groups) ethanolic A. lebbeck seed extract with at doses 100, 200 and 300 mg/Kg BW., respectively). All groups except group A chickens were experimentally infected with 500 sporulated oocysts of Eimeria tenella. The results showed that. In groups treated with the extract alone at a dose of 300 mg/kg, no particular histological abnormalities were seen, treated by Amprolium 1g/L in drinking water and control negative while, some lesions were observed in the groups treated at doses 100, mg/ Kg B. W. showed different stages of E. tenella maturation including schizont and microgametes were observed in crypt layer of cecum. E. tenella. Deferent stages of sexual and asexual of E tenella was observed within the necrotic epithelial cells’ debris near the surface of cecum lumen and at doses 200 mg/Kg.BW showed E. tenella microgametes was observed within epithelial necrosis cystic change in the sub mucosa and of cecum severe lesions changes observed in the group of control positive.
