Detoksifikasi Mikotoksin Melalui Optimalisasi Fungsi Rumen dengan Pemberian Ragi (MYCOTOXIN DETOXIFICATION THROUGH OPTIMIZATION THE RUMEN FUNCTION BY YEAST)

Abstract

Mycotoxins are toxic metabolites produced by some fungal species commonly found in food and feed, particularly in cereals. In intensive production systems, dairy cattle are commonly fed with cereal-rich diets and, consequently, are more exposed to micotoxins. Besides, such diet is often associated with a higher risk of rumen acidosis which can also affect the performance and the helath of animal. In addition, the efficacy of microbial detoxification can be reduced during acidosis. For instance, some authors observed a decrease in the number of protozoa that are responsible for the degradation of some mycotoxins. Another consequence of acidosis is the potential modification of ruminal absorption of mycotoxins, which until now has received scarce attention. Yeast Saccharomyces cerevisiae, probiotic additives have been shown to reduce the post-feeding drop in rumen pH and to increase the number of ruminal protozoa. This effect can be positive in reducing the absorption and toxicity of mycotoxins in ruminantia.
