e have used a murine model of subchronic mycotoxicoses produced by ingestion of mycotoxins. The five groups of animals studied were fed for 30, 60 and 90 days, respectively, with commercial diet (CD), experimental control diet (ECD), experimental with fumonisin B1 diet (EFD) and experimental with mixtures of mycotoxins diet (EMD). The animals fed EFD and EMD showed a significant increase in feed consumption/day with respect to the animals fed ECD (P < 0.005 for both groups). The biochemical measurements showed significant differences at 90 days in those animals fed EAD exhibiting a marked decrease in the values of alkaline phosphatase (ALP) and cholesterol (P < 0.05), along with a significant increase in calcium (P < 0.01). Differences in the decrease of the parameters studied were observed in mice fed EFD for triglycerides, cholesterol and calcium (P < 0.05 for all of them). The activity of aspartate transaminase (AST) increased significantly in animals fed EMD (P < 0.
