Bovaer: Methane-cutting cow feed trials on Arla dairy farms end

The conclusion of a significant UK trial involving a controversial feed additive intended to decrease methane emissions produced by dairy cows has recently occurred. Arla Foods, which owns the largest dairy co-operative in the UK, is currently assessing the outcomes of tests conducted on 30 farms before deciding on the future use of the product. When the Bovaer supplement trial was initiated last year, there were concerns raised regarding food safety, alongside misinformation and conspiracy theories circulating online. Videos surfaced on social media depicting individuals pouring milk down the drain in protest.

Following fresh concerns raised by farmers, an inquiry into Bovaer is underway in Denmark. Despite this, the manufacturer, DSM-Firmenich, maintains that the additive is both effective and safe. According to a company spokesperson, Bovaer has been utilized successfully for more than three years by numerous farmers across 25 countries. However, recent farmer reports expressing worries about cow health have prompted active engagement with relevant organizations to address these concerns thoroughly. Previous cases have not implicated Bovaer in the health issues raised by farmers.

Methane, a highly potent greenhouse gas, poses a severe environmental threat, being 28 times more powerful than carbon dioxide over a century. Bovaer, also known as 3-Nitrooxypropanol, has the potential to reduce cow methane emissions by 30-45% and support farmers in adopting more environmentally friendly practices. Approved by UK regulators, the supplement has received acknowledgment from the UK government as safe for human consumption, despite ongoing uncertainties about its broader application within the United Kingdom. Arla’s spokesperson mentioned that the trial findings are under evaluation at present.

Addressing the importance of animal welfare, the National Farmers’ Union (NFU) emphasizes that any new product must prioritize the well-being of livestock. In light of investigations in Denmark concerning methane suppressants, the NFU Dairy Board remains vigilant for further developments to ascertain product impacts. In Denmark, where reducing emissions is a crucial government objective, methane-reducing animal feed usage is compulsory for dairy farmers, assigning particular significance to products like Bovaer. The Danish Food and Veterinary Administration is closely monitoring reported cases of animal illness linked to Bovaer, seeking to determine the underlying causes and enforce necessary protocols. Multiple studies conducted by Aarhus University in Denmark provide valuable insights into methane reduction strategies and offer guidance to Danish regulatory bodies
