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 Alquerfeed Antitox, 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.
