Values are the mean of six replicates per treatment.
NCNT, non-challenged without any dietary treatment; CNT, challenged without any dietary treatment; THB, CNT with 3,4,5-trihydroxybenzoic acid at 0.1 g per kg; COM 100, CNT with combination of THB and oregano extract at 0.1 g per kg; COM 150, CNT with combination of THB and oregano extract at 0.15 g per kg; COM 200, CNT with combination of THB and oregano extract at 0.2 g per kg.
Values in a row with different superscripts differ significantly (p < 0.05).
dpi, days post-infection.
