Research interests

  • Substantial academic contributions at the interfaces between dairy nutrition, milk composition and rumen function - notably modelling of forage composition, dry cow feeding strategies, forages and fatty acids, fatty acids and fertility, and rumen diagnostics. 
  • Some work used directly by the animal feed industry – notably feed evaluation systems, feed values and dry cow strategies. Much more of my work has been used by farmers and advisers – notably to develop advice and models to predict and increase forage intakes, improve the utilisation of feed protein (reduce N pollution), improve milk composition, and facilitate the use of forage legumes in conventional and organic farming.
  • Current research is developing markers/proxies for digestive efficiency, feed efficiency and greenhouse gas emissions by ruminants – including through the use of gene-centric and 16S-based rumen metagenomics, as well as Nitrogen isotopic fractionation.
