As for the other PFAs, EUG proved as effective as ST in preventing the coccidiosis-induced decrease in TP and GLB concentrations (values not significantly different from h-CON; p > 0.05), but it had no effect on the coccidiosis-induced decrease in ALB (value not significantly different from d-CON; p > 0.05). This evidence concerns the gene ALB and coccidiosis.
