Effects of EO + OA on organ indices of weaned piglets.

Item	CON	LPS	EO + OA + LPS	SEM	P-value
Heart, g/kg	5.72	5.61	5.15	0.218	0.562
Liver, g/kg	29.76	32.71	36.56	1.012	0.163
Spleen, g/kg	2.32	2.96	2.59	0.142	0.107
Kidney, g/kg	5.42	6.05	6.24	0.212	0.408

CON = piglets fed the basal diet with intraperitoneal saline injection; LPS = piglets fed the basal diet and injected intraperitoneally with lipopolysaccharide (LPS) to induce stress; EO + OA + LPS = piglets fed the basal diet supplemented with essential oils (EO) and organic acids (OA) diet and injected intraperitoneally with LPS to induce stress.

Means with no letter superscripts indicate no significant differences (P＞0.05).
