Sife  Chikunya

Dr Sife Chikunya

Role

Senior Lecturer in Animal Science. I teach undergraduate (BSc) and postgraduate (MSc & PhD) degree programmes. I am also programme manager for the MSc in Animal Welfare and Conservation, MSc in Livestock Production Science and the MSc in Animal Health Science degree courses. I lead a number nutrition and biochemistry related modules in the School of Animal and Equine Science.

Biography

I hold the following academic qualifications: a BSc (Hons) in Animal Science (University of Zimbabwe), an MSc in Animal Nutrition (University of Cambridge), a PG Cert. in Learning and Teaching (Open University), and a PhD in Ruminant Nutrition (University of Cambridge). During my academic career I have received prestigious scholarships and awards, such as The Rotary Foundation Freedom from Hunger Scholarship, The Commonwealth and Livingstone Trust Scholarship, and The Farmers Clubs Charitable Trust scholarship. I hold several professional fellowships namely, Fellow of the Cambridge Commonwealth Society; Fellow of the Higher Education Academy, Honarary Member of the Farmers Club, Member of the British Society of Animal Science, and Member of the Nutrition Society.

Qualifications

PhD, Ruminant Nutrition (University of Cambridge)
PG Cert, Learning & Teaching in Higher Education (Open University)
MSc, Animal Nutrition (University of Aberdeen)
BSc (Hons), Animal Science (University of Zimbabwe)

Subject Areas

My main area of specialisation is animal nutrition. I teach module areas such as nutritional biochemistry, principles of nutrition, applied animal nutrition, and research methods.

Research

My areas of research interest include utilisation of nitrogen and energy sources in ruminants. I am also interested in the metabolism and utilisation of dietary fatty acids and vitamins in ruminants, and their effects on semen quality and ruminant food products such as meat and milk. Recently, I have started work to investigate the effects of essential oils on the activities or rumen micro-organisms in vitro.
