The aflatoxin M1 is a mycotoxin formed after the liver metabolization of aflatoxin B1, which is finally excreted in milk. Thus, becoming a risk for public health.

Objective

Evaluating the capacity of Silicoglycidol to reduce the excretion of aflatoxin M1 in goat milk, and its effect on production parameters.

Material and methods

The trial was carried out in the University of Córdoba. For the assay, a total of 18 Florida breed goats were used, randomly divided in 3 experimental groups.

• Negative control group: without uncontaminated feed and without Silicoglycidol
• Positive control group (AF): feed contaminated with aflatoxin B1
• Study group (AF + Silicoglycidol): feed contaminated and with Silicoglycidol

In order to determinate the concentration of aflatoxin M1, milk samples of each group were taken along the 28 days the study lasted. The effect of Silicoglycidol on milk production and composition and on blood parameters were also studied.

Results

In the study group, the concentration of aflatoxin M1 was of 0.087 µg/L. A 26.27% lower than the positive control group, in which the concentration of aflatoxin was of 0.118 µg/L.

No significant differences were found, even in the production and composition of milk and in biochemical parameters, between the negative control group and the study group.

Conclusions

The Silicoglycidol is able to significantly reduce the amount of aflatoxin M1 excreted in goat milk, without negative effects on production parameters.
