Since October 1, 2025, when many Danish dairy farmers began incorporating the synthetic additive Bovaer (containing 3-nitrooxypropanol) into their cows’ feed—alarming reports have come in of animals suffering from: stomach cramps, fevers, miscarriages, drastic drops in milk production, sudden collapses and in some cases, the need to be euthanised.

Marketed as a “climate-friendly” methane reducer, this product—produced by the Dutch-Swiss giant DSM-Firmenich—became a legal requirement for Danish dairy farmers to add into their animal feed for 80 days or for their cows to be fed extra fat throughout the year.
