a – d Values in a row with no common superscripts differ significantly (P < 0.05). Mean values are based on 4 birds per replicate and 8 replicates per treatment.
UC, unchallenged control; CC, challenged control; PE, plant extract; AM, antimicrobial (narasin and nicarbazin; 50 ppm each active compound); FAP, full dose of AM plus PE; HAP, half dose of AM plus PE.
The microbiota results in detail have been reported in a previous paper (Kumar et al., 2021).
