Research interests

I am particularly interested in organic agricultural production systems and production animal welfare. I have investigated the differences in production and milk composition from both organic and non-organic dairy systems in the UK, particularly the fatty acid content of milk (Journal of Dairy Science, 2006; 89 1938-1950), milk vitamin content (Journal of Research, 2007; In Press and online at http://journals.cambridge.org/) and the hygiene of the cows and milk produced (Journal of Dairy Research, 2007; 74 302-310). Other research work has investigated calf rearing on Scottish organic dairy farms and consumer perceptions of dairy animal welfare. Current work is investigating the epidemiology of gastrointestinal parasites in organic dairy cattle and, with funding from the Royal College of veterinary Surgeons Trust, a project is investigating control of mastitis on organic dairy farms with minimal antimicrobial use. I have recently collaborated with Duchy College in Cornwall on a DEFRA project to produce a web and DVD-based information resource on animal health and welfare for stakeholders in the organic agriculture sector.
