INTRODUCTION
The aim of this trial, conducted at Iowa State University (EE.UU) in April 2018, was to evaluate the reduction in aflatoxin (AF) absorption upon feeding with a mycotoxin binder (with Silicoglycidol), so it could prevent absorption by binding AF in the digestive tract. Absorption is estimated from AFM1 (aflatoxin M1) concentration in milk.

TRIAL DESIGN

• Holstein cows with 2 or more lactations and more than 200 days in milk were used for the trial.
• Cows were introduced to the feeding system at least 7 days prior to initiation of the study until adaptation was confirmed.

METHODOLOGY

• 4 cows were randomly assigned to each treatment within square.
• Cows were housed in one pen with free stalls and individual feeding gates. 
• Milking was performed 3 times a day (4:00, 12:00, 20:00 h). 
• Cows were fed ad libitum.

RESULTS 
As shown in the chart, AF concentration in milk was 27% less in cows fed with mycotoxin binder, which means that this binder with Silicoglycidol was useful even with high mycotoxin concentration in feed.

CONCLUSION 
This mycotoxin binder with Silicoglycidol is an effective strategy to mitigate aflatoxin contamination in dairy cattle.

This mycotoxin binder, manufactured by Biovet S.A., is commercially available under the name of Alquerfeed Antitox.
