Why internet storm about Bovaer is mistaken

I was interested to read the following statement from Milk & More who deliver my milk, who no doubt have seen an opportunity to seize a commercial advantage over Arla who are being boycotted by some consumers after an internet and media storm:

You may have seen recent news about the use of the Bovaer additive in the production of some dairy products - an experimental feed additive being trialled by some farms selling milk to larger companies and retailers to help reduce methane emissions from cows. We want to confirm that Milk & More isn't involved in these trials, and neither are the farms we work with. As an independent company, we're proud to partner with British farms that uphold high standards of animal welfare, food safety and environmental responsibility. Our fresh British milk is just as it should be - free from additives, fresh from trusted farms and delivered to your doorstep with care. With Milk & More, what's in your glass is simple: British milk. Nothing more, nothing less. My comment is that there is no evidence that this additive reaches the milk itself and we need to try out ways of reducing methane emissions from dairy cattle.  Unfortunately, one start up that hoped to achieve this objective has just collapsed. Bovaer is used in many countries including major dairy producers.
