Why birth of IVF calf Hilda in Scotland is being hailed as a milestone for greener farming

Hilda is part of the Cool Cows project, which is aiming to breed cows that produce less of the greenhouse gas methane

Vets working on a project to breed more environmentally-friendly cows have described as “hugely significant” the birth of a calf using IVF, saying it could accelerate the dairy industry’s journey to net zero.

The calf, named Hilda, is part the Dumfries-based Langhill Herd, which has been a source of data for the UK dairy industry for more than half a century.
