The experiment was carried out to evaluate the effect of the suckling vice and fumonisins on the performance and characteristics of some organs of post weaning piglets. Thirty-two littermates piglets where used into a factorial 2 x 2 (with and without suckling vice, with or without fumonisins in diet), with four replications and two animals for experimental unit. There was no interaction (P>0.05) between suckling vice and fumonisins for all analyzed variables. The final weight of piglets with suckling vice was 8% (P<0.05) lower than control group (25.2 x 27.5kg). Suckling vice did not influence (P>0.05) the feed intake. The addition of fumonisinas in the diet reduced (P<0.05) 20% the feed intake between 22 to 28 days of experiment. The weight gain of animals fed fumonisin diets was 14% lower (P<0.05) than control group. The suckling vice got worse (P<0.05) 11% feed conversion rate (1.52 x 1.68). Fumonisin diets got worse (P<0.05) 13% feed conversion rate from 15 to 21 days of experiment. The suckling vice did not modify (P>0.05) organ weights. Fumonisins increased (P<0.05) the liver weight (820 x 693g) and reduced weight of heart (126 x 148g), stomach (291 x 384g), intestine (2,015 x 2,577g), pancreas (55 x 74g), and lung (291 x 350g). The suckling vice and fumonisins influence negatively the animals performance, but the vice does not modify organ weights.
