RESUMO
One of the main illnesses within the poultry industry is coccidiosis. Anticoccidial medicines applied in the poultry industry show many shortcomings and new control measures are necessary. The current research aimed to study the effect of extract of Citrullus colocynthis and Juglans regia peel on growth performance, gut bacteria, Haematological, Anticoccidial Index (ACI), and Optimum Anticoccidial Activity (OAA) of coccidiosis-infected domestic chicken. The maximum weight gain was observed in the groups treated with 0.001% and 0.01% C. colocynthis extract. Moreover, 0.01% C. colocynthis extract treatment increased two factors of ACI and OAA by 121.42 and 109, respectively, which were higher than commercial anticoccidial (Sulfaclozine). The extract of C. colocynthis fruit and J. regia peel decreased monocytes and eosinophils haematological factors and increased basophils in birds infected with Eimeria. Both extracts modulated intestinal microbiome haematological factors in birds infected with Eimeria, while J. regia peel extract had better performance than C. colocynthis fruit extract. These results indicate that used C. colocynthis and J. regia extracts have an anti-coccidial effect and the potential to control Eimeria infection.
