Messing with the rumen will either increase or decrease the productivity. Methane is high in calories so it should intuitively increase the productivity, which they currently think is true but unproven - https://research.csiro.au/futurefeed/faq/ https://research.csiro.au/futurefeed/faq/ It also should increase productivity on all ruminants in theory. I like this bit - "While analysing the gas samples using gas chromatography (GC) there was a repeating scenario of a 10-20% methane reduction, until suddenly one sample showed no methane! At first it was assumed that there was a problem with the GC so the test was repeated, and when the same result was replicated we had our moment of discovery. Those results have reproduced on every subsequent test and the red seaweed Asparagopsis is the star performer."
