Dr Jordana Rivero-Viera

Dr Jordana Rivero-Viera Chairperson

Jordana Rivero’s work is focused on livestock grazing systems with an emphasis on sustainability. Her research covers main aspects of grazing livestock systems such as pasture and grazing management, animal performance and emissions, forage quality and breeding objectives for several livestock species. Jordana started her career in Uruguay, developing breeding goals and breeding objectives for dairy cattle under pasture-based systems, and in 2013 she was awarded a PhD in Agricultural Science from the Universidad Austral de Chile where she gained experience in grazing systems and NIRS applied to feeds and animal products. Jordana also collaborated on the characterisation of a creole sheep breed, regarding grazing behaviour and meat quality. During her postdoctoral fellowship, she studied the joint effect of agronomic management and cultivar of perennial ryegrass on grazing dairy cows ‘performance and nutrients use efficiency. In her current role at Rothamsted Research, Jordana is involved in a variety of fascinating research projects related to nutrient flow efficiency through the soil-plant-animal continuum, animal behaviours and welfare, animal genetic selection, grazing systems, sward diversity and key performance indicators. Jordana is also an active participant of the NCC North Wyke Farm Platform (Devon), where she works on grazing management of beef and sheep, pasture production/utilisation, animal behaviour and product quality.

Dr Jude Capper, PhD ARAgS

Dr Jude Capper, PhD ARAgS Committee Member

Jude L. Capper, PhD, DSc (h.s.)  ARAgS has two main roles: she is the ABP Chair and Professor of Sustainable Beef and Sheep systems at Harper Adams University in Shropshire, UK; and is an independent Livestock Sustainability Consultant based in Oxfordshire, UK.

Jude's research focuses on modeling the sustainability of livestock production systems, specifically dairy, beef and sheep. She is currently working on projects relating to on-farm greenhouse gas emissions from UK beef production; climate footprints of smallholder farming; the impacts of livestock health and welfare on system sustainability; and technology use in South American beef production. She sits on the National Beef Association board; is Chair of the Route Panel for Agriculture, Environment and Animal Care and Vice-Chair of the Green Apprenticeships Advisory Panel at the Institute for Apprenticeships and Technical Education.

She has an active social media presence and spends a considerable amount of time de-bunking some of the more commonly-heard myths relating to livestock production. In 2021, Jude was awarded both an honorary doctorate (DSc honoris causa) by Harper Adams University, and the Sir John Hammond Award by the British Society of Animal Science and British Cattle Breeders Club, in recognition of her contributions to the UK livestock industry.

Dr Michael Rose

Dr Michael Rose Committee Member

Mike graduated with a PhD from the University of Newcastle upon Tyne (UK) in 1993. His PhD was an investigation of the extent of the milk yield response of dairy cows to bovine somatotropin. Following this he worked in the National Institute of Grassland and Livestock Research (Japan), for seven years as a research officer, where he studied the metabolic endocrinology of dairy cows. He moved to Aberystwyth University (UK) in 2000 and was there until 2019. He moved to the University of Tasmania in 2019 where he is Interim Director, Tasmanian Institute of Agriculture.
