^a–c

Means in a column not sharing a common superscript differ (P < 0.05).

Values are means of 6 replicates; NC = Negative control; PC = Positive control; WYC = Whole Yeast + LPS challenge; YCWC = Yeast cell wall extract + LPS challenge; YGC = Yeast glucan extract + LPS challenge; YMC = Yeast mannan extract + LPS challenge; ZNBC = Zinc bacitracin + LPS challenged; SALC = Salinomycin + LPS challenged. FI = Feed intake; BWG = Body weight gain; FCR = Feed conversion ratio.
