SUMMARY
  • EU (EFSA) maximum permitted levels for aflatoxins in dairy complete feed is 5 μg/kg (5.6 μg/kg DM), these levels may negatively impact health and reduce animal performance.
  • Anpario’s Anpro significantly reduces aflatoxin (AfB1) and its main secondary metabolite (AfM1) levels in blood and milk of dairy cows.
  • Anpro significantly lowered somatic cell counts over the treatment period.

BACKGROUND
  • Mycotoxins are produced by moulds and may still be present in processed feed and bedding.
  • Mycotoxins are stable compounds which are resistant to heat and chemical treatments.
  • Mycotoxicosis can cause infertility, increased incidence of mastitis, reduced feed intake and reduced milk production in dairy cows leading to high economic losses.

 

TRIAL DESIGN

An independent in vivo trial was conducted at IRTA Ruminant Production Facility (Spain) to assess the efficacy of Anpro in binding aflatoxin (AfB1) in the rumen to prevent the transfer of aflatoxin to the blood and milk of dairy cows. 24 healthy, high yielding Holstein dairy cows (providing ~36 kg milk/day @ 140 days in milk) were allocated to two groups: the Control group were fed daily (basal diet + 100 g feed), the Anpro group were fed (basal diet + 80 g feed and 20 g Anpro). A corn drench to supply 5.6 μg AfB1/kg DM was given to each cow daily, following the morning milking. Blood and milk samples were taken on days 15 and 21, subsequently analysed for AfB1 and AfM1 respectively.

RESULTS
  • Anpro given in feed can effectively reduce aflatoxin (AfB1) transfer from feed to blood (fig 1).
  • Anpro significantly reduced transfer of aflatoxin (AfM1) to the milk (fig 2).
  • Anpro in feed can significantly reduce aflatoxin transfer from feed to milk, therefore reducing the aflatoxin risk posed to dairy and end consumers of dairy products.
