Comparative values of the relative weight gain (RWG), survival rate (SR), lesion score of duodenum and jejunum. A relative weight gain (RWG) in birds of different treatments. B survival rate (SR) in birds of different treatments. C lesion score of duodenums in birds of different treatments. D lesion score of jejunums in birds of different treatments. PC avilamycin-positive control. CC challenge control. NC no additive supplementation and no challenge. Astricts signify statistical significance in comparison to the control group (*p < 0.05, **p < 0.005, ***p < 0.0005, ****p < 0.0001)
