Breed for CH4nge project update June 2024

Breed for CH4NGE: is a three-year initiative funded through DEFRA’s Farming Innovation Programme.

The goal is to breed productive, efficient maternal sheep with a naturally low carbon footprint.

To achieve this:

  • Measuring methane output in fully performance recorded lambs to help us identify the best sheep to breed from

  • Gathering data on feed efficiency and rumen biology to help develop a sustainable breeding strategy for ewes that make better use of our land and have a lower carbon footprint

  • Demonstrating the impact that efficient, low methane sheep can have on whole farm carbon footprint

  • Sharing what we find with the wider sheep industry so that we all benefit from improved efficiency

The partnership is made up of commercially driven breeders using performance-recording to deliver profitable maternal genetics at significant scale, with leading academics, a key lamb supply-chain and industry bodies whose networks extend to thousands of English sheep farmers.
