The Swiss Farmers' Union and Suissepigs have decided to prohibit the use of the hormone PMSG, sourced from the blood of pregnant mares, in their farms due to concerns over its production conditions and potential conflict with high animal welfare standards. This rule will apply to farms under the AQ-Viande Suisse program, covering around 95% of Swiss livestock farms, effective September 1, 2022. The ban will be enforced from 2023, with veterinarians being informed of the prohibition.
