Breed for CH4nge: New Genetic Index to Lower Methane Emissions in Sheep

The Breed for CH4nge project has developed a new breeding value index to help sheep farmers reduce their carbon footprint. By identifying heritable traits linked to lower methane output, the tool allows breeders to select animals with a naturally lower environmental impact without sacrificing productivity. Funded by Defra, the initiative used data from 40 flocks to prove that methane emissions are heritable. The new tools will be integrated into performance recording systems like Innovis and Signet to help the UK sheep industry improve sustainability and meet consumer demand for low carbon meat.

Interesting to see this moving toward a standardized index. The real test will be whether this links to actual subsidies or carbon credits. Without a financial incentive for the farmer, adoption of these breeding values might be slower than the researchers hope.

Exactly. The article mentions a win win for the bottom line, but doesn't specify how. Is it just lower feed costs or is there a price premium for low methane lamb?

The 20 percent less feed for the same growth rate is the most concrete stat here. I wonder if the methane reduction scales linearly with that feed efficiency or if there is a floor to how much you can actually cut through genetics alone.
