oocysts/bird: (A) infected and un-supplemented diet, (B) infected and supplemented diet (P. emblica powder 1 g/bird/day), (C) infected with P. emblica-treated oocysts and un-supplemented diet and (D) infected and diet supplemented only from day14. In vivo experiments were terminated on day28. Significant sporulation inhibition and oocyst lysis (p < 0.05) in vitro were observed in a concentration-dependent with P. emblica treatment. In in vivo experiments, group B showed the highest weight gain, lowest fecal oocyst excretion and mildest histopathological lesions. Extracts of P. emblica remarkably inhibited oocyst sporulation, reduced the oocyst infectivity and lowered the fecal oocyst excretion, and reduced the pathogenicity of E. tenella in chickens. Therefore, P. emblica extract demonstrates great potential to be an effective alternative anticoccidial agent.
