Prevention and Detoxification of Mycotoxins in Feed

Abstract

Through a comprehensive review of published reports on mycotoxin removal strategies, this work aims to update the understanding of the removal of mycotoxins present in the feed. Mycotoxins in feed: from prevention in the field to detoxification by adsorption or transformation. Mycotoxins are secondary metabolites present worldwide in agricultural products and produced by fungi that cause a toxic response (mycotoxicosis) when ingested by animals. Prevention of mycotoxicosis includes strategies before and after harvesting. The best way to reduce the content of mycotoxins in the feed is to prevent the formation of mycotoxins, but it is often not enough, so other methods are needed. The most common approach in the feed industry is the inclusion of sorbing materials in the feed, which provides more or less selective removal of toxins by adsorption during passage through the gastrointestinal tract. Another reliable approach is the addition of enzymes or microorganisms that can remove toxins from some mycotoxins.

Oilseed flax and alfalfa as sources of nutrient elements in the Central region of non-chernozem zone of Russia

“…The high content of nutrients, in comparison with other feeds, makes alfalfa an attractive crop for widespread use in animal husbandry. The wide ecological plasticity of alfalfa allows it to be grown in high latitudes, demonstrating good yields and low disease incidence [13].…”

“…In alfalfa, the ash level in different growth phases can vary: 103 g/kg in the stalking phase; 111 g/kg at the beginning of flowering and 98 g/kg at the end of flowering [12,13]. Most of the ash is contained in the leaves [4].…”
