Table 5. Effect of in vivo exposure of piglets to ZEA on anti-inflammatory cytokine protein level in spleen tissue.

Cytokine concentration (pg/ml) b	Experimental groups a		ZEA effect c
	Control	ZEA contamination	P-value
IL-10	11.77 ± 1.04	11.25 ± 0.45	NS
IL-4	22.64 ± 1.39	19.83 ± 1.47	NS

^aPigs were fed for 18 days with a control diet or a diet contaminated with ZEA. At the end of the experiment, spleen samples from all animals (n = 5 per group) were collected and analyzed for cytokine level by ELISA.

^bresults are expressed as concentration in pg/ml (mean ± SEM).

^cAnova-one way followed by Ficher tests were realized to analyze the effect of ZEA treatment on cytokine production. Values of P < 0.05 were considered significant, NS = not significant.
