Richard - an Australian company are producing an additive for dairy cow feed from seaweed which in small quantities (circa 6%) reduces methane emissions by up to 40% a totally natural additive and really positive for emissions reduction without any nasty chemicals!
Cheers!
Robbie, thanks that's good to read and the right direction ahead.
The Arla etc additive can cause cancer in sufficient strengths so who's so say this is not building up in the cows body (as Ragwort does) and being passed on to the consumer these chemical compounds are not the way ahead.
