Mitigating the impact of aflatoxins on the milk quality and performance of dairy cows

Aflatoxins pose a significant risk to both cow’s health and the quality of milk

Aflatoxins are one of the most harmful mycotoxins for dairy cows and are known for their toxicity on the health and productivity of dairy cows and as contaminants of many foods, including milk and milk-based products. It is adviced to adopt proactive strategies to minimize aflatoxin exposure, including careful feed management, monitoring programs, and the use of mitigation measures. By addressing these risks, farmers can safeguard the well-being of their dairy cows and ensure the production of high-quality, safe milk for consumers.

A mycotoxin risk mitigation programme of a dairy herd requires a holistic approach

A mycotoxin management programme for dairy cows should include:

  • Early identification of feed ingredients that are contaminated with mycotoxins of dairy cows
  • Reducing growth of moulds that can produce mycotoxins while the crop is on the field or in storage
  • Adding silage inoculants or mold inhibitors such as Fyvalet Silage for ruminants when the silage clamp is being filled and spraying mold inhibitors such as Selko TMR on the face of the silage after cutting
  • Adding mycotoxin mitigation products for dairy cattle into the TMR at feeding, this can be done by adding the product directly to the TMR or by feeding compound feed with the mycotoxin mitigation product included

Selko Toxo-MX

Selko Toxo-MX

Selko Toxo®-MX is part of our Selko Mycotoxin Risk Management Programme and consists of smectite clays, which have shown to have a high binding capacity for aflatoxin B1. With the bioavailability of aflatoxin B1 reduced, the production of aflatoxin M1 is diminished, meaning lower levels are excreted into the milk.

Administration

Selko TOXO-MX is presented as a dry powder. The recommended dose is based on the level of aflatoxin contamination of the ration.

  Low risk Medium risk High risk
Dairy 25g/head/day 50g/head/day 75g/head/day
Calves 15g/head/day 30g/head/day 45g/head/day
Beef 25g/head/day 50g/head/day 75g/head/day

Figure 1, Levels of Aflatoxin M1 in milk of dairy cows fed a ration without aflatoxin B1 (Group CRT-0), a ration contaminated with aflatoxin B1 (Group CRT-AFLA) or a ration contaminated with aflatoxin and treated with Selko Toxo MX (Group TRT).

Figure 2, milk yield per kg DMI, Fat Corrected Milk yield per kg of DMI and Energy Corrected Milk per kg DMI in dairy cows fed a ration contaminated with aflatoxin B1 (Group CRT-Afla) or a ration contaminated with aflatoxin and treated with Selko Toxo MX (Group TRT).

Trial carried out with Selko TOXO-MX

Problems with aflatoxins that are related to Aflatoxin M1, a metabolite of Aflatoxin B1, are well understood. Aflatoxins can be excreted into the milk of dairy cows that consume contaminated feed. This is a significant concern because aflatoxins are carcinogenic, and the presence in milk can pose a risk for human health. Health problems in dairy cows caused by Aflatoxin B1 are less commonly known.

A recent trial with mycotoxin analysis showed that exposure to feed with Aflatoxin B1 concentrations below the European Union (EU) limit for regulation of mycotoxins results in Aflatoxin M1 excretion in milk that exceeded the EU regulatory limit of 0.05 ppb (see Figure 1). In the same trial, Selko TOXO MX significantly reduced the transfer of Aflatoxin B1 in feed to Aflatoxin M1 in milk and also significantly improved feed efficiency measured as milk production per kilogram of dry matter ingested (see Figure 2).
