At least seven cows lost consciousness and died on Saturday at a farm in Doetinchem in the Netherlands after gas was released during the mixing of manure.
Upon noticing the gas, the farmer contacted the fire department, which conducted measurements. The farm has around 250 cows, mainly used for the dairy industry.
The gas was released in a stable, where nearly 35 young cows were kept. Ten animals lost consciousness, and some of them did not survive. The owner of the farm was devastated and told local media that he had “never experienced this in 41 years.” The cause of the incident remains unclear.
