Achieving Net Zero Dairy Farming

Dr John Webster is Emeritus Professor in Animal Husbandry at the University of Bristol, UK. He established the Animal Welfare and Behaviour Group at the University of Bristol, one of the largest and most highly-regarded of its kind in the world, and was a founder member of the Farm Animal Welfare Council which pioneered the Five Freedoms for farm animals. Professor Webster is editor of an earlier Burleigh Dodds Science Publishing volume: Achieving sustainable production of milk Volume 3: Dairy herd management and welfare (published in 2017). Other key books written or edited by Professor Webster include Understanding the Dairy Cow and Animal Husbandry Regained: the place of farm animals in sustainable agriculture.
