Reduction of aflatoxin M1 in milk of Holstein cows administered a clay adsorbent

Abstract

Aflatoxins (AF) are secondary metabolites commonly found in dairy feeds that can be transferred into the milk of lactating cows. Because of their negative effects on dairy cows and humans consuming contaminated milk, they are strictly regulated. The objective of the current study was to evaluate the efficacy of an aluminosilicate clay at reducing the transfer of aflatoxin M1 into the milk and its impact on production parameters of lactating dairy cows fed diets contaminated with aflatoxin B1. Additionally, the study aimed to determine the effects of the aluminosilicate clay on body condition, body weight, and respiratory rates of cows consuming aflatoxin B1-contaminated feed.
