ADFI, Average daily feed intake; ADG, Average daily gain; F:G, Feed:Gain; CHA, chlorogenic acid.

At 13th day after weaning, the rats (LPS group and CHA groups) received intraperitoneal administration of LPS.

CHA20, rats supplemented with 20 mg/kg chlorogenic acid; CHA50, rats supplemented with 50 mg/kg chlorogenic acid.

^a,bMeans in the same row with different superscripts differ (P<0.05).
