ASHWORTH CHRIS

Dr. Chris Ashworth is a Global Research and Development Veterinarian for Zinpro Performance Minerals, based in Greenwood Arkansas. He is a 1987 graduate of Louisiana State University School of Veterinary Medicine. After veterinary school he completed a one-year large animal internship and then completed a three-year food animal medicine and surgery residency with an emphasis in internal medicine and infectious disease, all at the U. of Illinois at Urbana-Champaign. Dr. Ashworth has been a national dairy and beef technical veterinarian for Purina Mills, Monsanto, and Elanco Animal Health companies. He joined Zinpro Performance Minerals in 2017.

In the field of lameness his area of interest is lameness in beef bulls and aged beef cows, attempting to get one more productive year of use, out of both these animals.

Dr. Ashworth lives in Greenwood, AR and also owns a 200 head Registered Black Angus seed stock operation. He is responsible for research and development studies across a number of species from cattle to companion animals for Zinpro Performance Minerals.

CARTER STUART

Stuart Carter – University of Liverpool, UK
Emeritus Professor of Veterinary Pathology.

Have been an academic at Liverpool University Veterinary School since 1985 working in various areas of infectious disease research in species ranging from farm animals, small animals, horses and including other variously exotic species from seals to camels. Roger Blowey triggered my interest (and our long term collaboration) in digital dermatitis in 1993 and it has continued to this day. The main interest in all this time has been the infection biology of digital dermatitis (in cattle and sheep), primarily in bacteriology, immunology and the genetics of susceptibility.

The Liverpool Livestock Lameness Group has developed from this work in which I am privileged to work with George Oikonomou and Nick Evans. Our work is all aimed at identifying and implementing effective disease interventions/prevention, and recent developments in genomics and AI are making this a much more achievable aspiration.

CASELLATO ANDREA

Andrea Casellato, DVM Freelance, lives in Milan, Italy. He graduated in 2001 from the University of Milan. In the same year he attended a course of Bovine Veterinary which included lessons regarding the foot and the limb diseases. In that context he met teachers who would become his professional mentors in the field of "lameness in cattle" and then colleagues. He began to learn that the foot hides a small world of knowledge to explore. After a period in which he also worked as a veterinary surgeon, in 2004 he moved his work only to foot health. From then till today, he works as a hoof trimmer, podiatrist and consultant in dairy farms located in the central part of the Po Valley.

He has attended national and international training courses and conferences. He has also participated as a lecturer in many national courses for veterinarians and hoof trimmers of foot and claw health topics. He has always been passionate about data collection and analysis. Since 2004 he has collected data and analysis on lameness using Microsoft Excel. Since 2017 he has developed a web application with a computer engineer with the aim of having a better, constantly and easily upgradable tool to increase the understanding of the epidemiology of claw diseases at the herd level.

TELEZHENKO EVGENIJ

Evgenij Telezhenko is a researcher at the Unit of Animal Environment and Building Function, Department of Biosystems and Technology, Swedish University of Agricultural Sciences. Evgenij received his PhD in Animal Science at the Swedish University of Agricultural Sciences Swedish in 2007 and provided an important contribution to the field by investigating effects of different flooring systems on gait, behaviour, foot health and biomechanics in dairy cattle.

He then held a position as a postdoctoral researcher at the Animal Welfare Program (University of British Columbia, Canada) in 2009-2010. Next, he worked in the dairy industry and then returned to academia in 2017 with new ideas and experience. A recent long-term project led by Evgenij scrutinized various flooring systems in Swedish dairy free-stall barns, focusing on their influence on slipping risk, long-term effects on animal welfare and health, Swedish farmers' motivations for choosing particular flooring designs, and the economic impact of these choices on farming. He is currently working on research projects that explore various aspects of hoof trimming in cattle and pigs.
