Abstract:
Avian coccidiosis, an important protozoal disease of chicken triggered by coccidian protozoa
of genus Eimeria, causes considerable economic losses to broiler producers. The study was
designed to assess the efficiency of Origanum majoranum aqueous extract (OMAE) on E.
tenella-infected broiler chicken. Birds were divided into four groups including: positive control
(PC, challenged with 5×104 sporulated oocysts of E. tenella at the 12th day of age), PC+OMAE
(challenged with E. tenella oocysts at the 12th day of age and received OMAE (125 mg/kg BW)
orally, started at the 7th day of age, and continued for 14 consecutive days), OMAE (received
OMAE (125 mg/kg BW) orally, at the 7th day of age, for 14 consecutive days), and negative
control (received basal diet only). Anticoccidial efficacy of OMAE was evaluated by complete
blood picture, serum chemistry, serum protein electrophoresis, antioxidants markers, cecal
oocysts count, and cecal lesions score. Briefly, collected data indicated that supplementation
of OMAE could increase antioxidants concentrations and improve changes in hematobiochemical parameters and serum protein fractions, as well as decrease cecal oocysts
count and reduce cecal lesion scores in E. tenella-infected birds. In conclusion, OMAE restores
oxidant-antioxidant balance, and its supplementation in broiler chicken can alleviate E.
tenella-infection and reduce its severity.
