Research interests
I have a background in animal science and grazing ecology and specialise in developing and testing management strategies for upland systems. My research interests include: species and breed differences in diet selection and ingestive behaviour, conservation grazing, nutrient supply from forages, greenhouse gas emissions from grazing animals, and the bio-energy potential of semi-natural grasslands. I have worked with a range of animal species (sheep, cattle, goats, ponies, deer, South American camelids) and pasture types (cultivated, improved permanent pasture and semi-natural grass and heath communities), as well as fresh and ensiled alternative forages (high WSC grasses, forage legumes, brassicas, pulses and bi-crops), to deliver a range of products (meat, fibre, habitats and biorenewables).
