Was evaluated the efficiency of the additives antimicotoxinas (AMM) in detoxification of mycotoxin in sow during the reproductive phase. The experimental design was randomized with two treatments: T1 (group composed by 18 sows that received a diet naturally contaminated by Zearalenone (ZEA), Fumonisin B1 (FB1) e Fumonisin B2 (FB2) + 2 kg / t of AAM); T2 (group composed by 18 sows that received a diet naturally contaminated by ZEA, FB1 e FB2). Each sow represented an experimental unit. The experiment was carried out during 42 days (21 days before the lactation and 21 days in lactation period). During the experiment the ration factory evaluated the occurrence of mycotxins and the level of fungal contamination (ergosterol) and water activity (Aw) in the ration. The parameters evaluated were: the volume of vulvar arrays and gilts; reproductive performance (account of piglets born, piglets born dead and mummified piglets as well the weight at birth and postweaning. Beside that gammaglutamyltransferase, alkaline phosphatase, aspartate aminotransferase, glucose, cholesterol, bilirrubin, phosphorus, calcium, magnesium, sodium, potassium, ionic calcium and protein concentrations were performed. The data were analyzed using statistical test Analysis of Variance (ANOVA) and media comparison was done by Tukey test (p<0.05). The results showed that six sample presented medial level 0.4mg/kg of ZEA, 1.6mg/FB1, 0.56mg/kg of FB2, 1,84 mg / kg of ergostherol and an average of 0,60 Aw. The correltion between ergosterol and mycotoxins was moderate to low. The vulva swollen of the sows did not presented significant difference. However the vulva swollen the gilts have statistical difference (p<0.05). In reproductive performance did not significant difference in respect to quantity of piglets born, piglets born dead, mummified piglets and weight at birth. But, it was observed difference at postweaning (p<0.0018) and weight gain (p<0.005). No statistical difference were observed in the serum analysis, except calcium (p<0.0016) between treatment. The adsorbent did not interact to minerals studied and addition of 2 kg / t of AAM was positive, once there is not vulva swollen of the gilts and it contributed to weight gain on 21th days.
