Profile

I am a reader in livestock nutrition and Director of International (Research).  My research interest is improving the use of feed nutrients for efficient livestock production: farming to make use of feeds that people cannot eat to produce foods that people can eat, while minimising the environmental impact of the processes.

  • Use of forages for improved livestock production

  • Short and long term effects of reducing protein intake of growing and lactating dairy cattle on immediate and subsequent productivity

  • Dietary manipulation to reduce methane emissions from ruminant animals

  • Sustainable intensification of forage-based production systems

  • Improvement of temperate and tropical forages for improved farmer livelihoods

Teaching

- RCUK-CIAT Newton Fund - tropical forage-based diets for Colombian cattle, with CIAT and Bangor
Cleaner Cows - an NRN-LCEE project to reduce environmental impacts of cattle production, with Bangor and Cardiff
CowficieNcy - an EU Marie Skłodowska-Curie RISE programme to improve cattle N use efficiency, with partners in the EU and the US
