ISSUE FOCUS 22 FEED & ADDITIVE MAGAZINE August 2022 demonstrate the importance of an integrated approach. It starts from optimal crop management, includes harvesting and storage of raw materials and finally the management of TMR (Figure 1). Innovations in organic acid application (Selko Fylax range) are allowing for better storage of raw materials in silos, leading to optimal silage production and face management, and preventing heating of TMR (Selko-TMR). Mycotoxin mitigation products (Selko TOXO range) can be added to TMR directly or via concentrate to effectively reduce mycotoxin risk for animal health and human health, by keeping AFM1 levels within statutory limits. As mycotoxins differ in their structure, scientific research has shown that all mycotoxins cannot be bound by a mycotoxin binder. Addressing this limitation, Selko developed the TOXO portfolio, using four modes of action to reduce the absorption of mycotoxins and to protect the animal against toxin damage. Based on the main objective of the feed mills or dairy farms, a selection of the right TOXO product can help in meeting those objectives. How to manage Aflatoxin M1 in dairy cows? Milk AFM1 management should be based on HACCP approach. This means all the critical control points of AFB1 entry into the dairy feed must be given proper attention and efforts should be made to prevent such entry. Regular feed mill audits and hygiene management will help in controlling unwarranted levels of AFM1 in milk. Since moulds are ubiquitous, irrespective of the efforts made there still be a chance of AFM1 appearing in the milk. The U.S. Food & Drug Administration (FDA) has set an upper limit of 0.5ppb AFM1 in milk while for the European Union has set this limit to 0.05ppb, ten times more stringent than FDA. Depending on the country the feed mills or dairy farms are in, these regulations should be followed both for milk used for domestic consumption as Figure 1. Tackling mycotoxin risk requires a fully integrated approach.
