The study evaluated the effects of graded challenge of E. maxima on growth performance and gastrointestinal biomarkers in the broiler chickens. Birds were challenged with E. maxima on day 14.
aLow, 12 500 oocysts of E. maxima; Medium, 25 000 oocysts of E. maxima; High, 50 000 oocysts of E. maxima; BW body weight, BWG body weight gain, FI feed intake, FCR feed conversion rate.
bThe P values indicate whether the analyzed parameters linearly or quadratically responded to the graded challenge doses of E. maxima.
