Trevor DeVries
University of Guelph

Presentation: Consistency is Key When it Comes to Feed Consumption in Dairy Cows!
Wednesday, March 6, 2019; PM Concurrent Session III
Presentation: Managing Robot Herds to Optimize Health and Welfare
Friday, March 8, 2019; AM Plenary Session VII

Trevor DeVries is a Professor in the Department of Animal Biosciences at the University of Guelph and Canada Research Chair in Dairy Cattle Behavior and Welfare. Trevor received his B.Sc. in Agriculture from The University of British Columbia (UBC) in 2001. Immediately following he began graduate studies at UBC, where he received his Ph.D. in 2006. Following that, he spent one year as a post-doctoral fellow with Agriculture and Agri-Food Canada. In 2007 he was appointed as faculty with the University of Guelph in the Department of Animal Biosciences. In that position Trevor leads a highly productive research program focused on dairy cattle behaviour, nutrition, management, and welfare.

Presentation Overviews: In his first presentation (Session III), Trevor will discuss how dairy cow health and production are optimized when cows have access to a balanced diet, and consume that ration as presented, and in a manner that is good for them. That consistency in diet consumption is only achieved through the use of quality feed ingredients, proper ration formulation and preparation, and management of that ration at the feed bunk. This includes managing forage particle size, ration moisture content, and consistency, timing, and frequency of feed delivery and push-up.

In his second presentation (Session VII), Trevor will discuss how the health and welfare of dairy cows managed in robotic milking herds are highly dependent on housing design and management, and have a direct impact on productivity. Robot milked cows must have both the desire and ability to milk voluntarily, as well as meet their other behavioural needs. To achieve these, producers must focus on minimizing the risk of conditions such as lameness, injuries, ketosis, and mastitis through proper nutritional management and ensuring clean, comfortable housing.

J.C. (Kees) Plaizier
University of Manitoba

Presentation: What is Gut Health and How to Improve It?
Wednesday, March 6, 2019; PM Concurrent Session III

J. C. (Kees) Plaizier is Professor in Dairy Nutrition and Management at the University of Manitoba. He grew up on a dairy farm in the Netherlands, and obtained his M.Sc. in Animal Science at Wageningen University (the Netherlands), in 1986. Subsequently, he worked for the Food and Agriculture Organization of the United Nations for six years. During that period, Kees collaborated with scientists in developing countries on improving the productivity of local livestock. In 1997, Kees obtained his Ph.D. in Animal Science at the University of Guelph, and remained at the University of Guelph as a post-doctoral fellow working on dairy cattle nutrition.  In 2000, he joined the faculty of the Department of Animal Science of the University of Manitoba.

His current research program focuses on the enhancing health and nutrient utilization of dairy cows, as well as environmental sustainability of dairy farms, and the evaluation of novel feeds for cattle. He has authored or co-authored over 90 manuscripts in scientific journals and numerous conference abstracts, articles, extension materials and technical reports. Since January 2014, Kees has been Editor-in-Chief of the Canadian Journal of Animal Science. At the University of Manitoba, Kees teaches dairy cattle production and ruminant nutrition at the diploma, degree and graduate levels.

Presentation Overview: In his presentation, Kees will discuss how the need to feed high grain diet to high yielding dairy cows and beef cattle jeopardizes their gut health. As alternatives to these high grain diets are not available, feeding strategies that allow feeding such diets without impacting gut health must be developed. Gut health encompasses the health of digesta, epithelia, and microbiota in the digestive tract. Hence, subacute ruminal acidosis (SARA) is only one aspect of poor gut health. Improving the functionality of gut microbiota and the epithelia of the rumen and the hindgut contribute to improved gut health. Strategies such as supplementation with buffers, probiotics and yeast products can be used to improve these functionalities.

Frank van der Meer
University of Calgary

Presentation: Bovine Leukemia Virus in Your Herd? Get Rid of It!
Thursday, March 7, 2019; PM Concurrent Session V

Frank van der Meer graduated from the Faculty of Veterinary Medicine at Utrecht University in the Netherlands in 1996. He worked for 1.5 years in large animal practice and returned to the Utrecht University to conduct research on horse reproduction. His strong collaboration with the virology department during that time sparked his still ongoing passion for viruses. Frank completed his PhD on the activity of antiviral compounds to Retro- and Nidoviruses in 2007. In May 2008 he joined the newly established Faculty of Veterinary Medicine at the University of Calgary (UCVM) to teach vaccinology, virology, diagnostics and immunology to veterinary students. Congruently, he continued his postdoctoral research in the Faculty of Medicine, focusing on Human Immunodeficiency Virus infections. In October 2013 he was appointed as Assistant Professor of Global Health and Infectious Diseases at UCVM.

Bovine viral diarrhea virus is of special interest due to its impact on the cattle industry, involvement in the bovine respiratory disease (BRD) complex and several unique virological features. He currently studies the transmission and evolution of this virus and the consequences of BVDV variability on vaccination strategies. Bovine Leukemia Virus and its impact on the dairy industry is his new target for exploration, a program funded by ALMA and Alberta Milk started in September 2015 aiming to design a BLV control strategy for Alberta. The bovine respiratory ‘virome’ (all viruses in the cow’s upper and lower respiratory tract) will be characterized, especially the normal changes that will occur during the cow’s life, following vaccination, antimicrobial treatment and when a cow gets sick. This is in combination with the ALMA/Genome Alberta project which aims to shed more light on the microbiology of BRD. The last topic he is currently working on is the exploration of wildlife viruses in the Canadian arctic. That viruses infect our wildlife is clear, but which viruses these are and what the impact is, is part of this study. Frank’s activities reach well beyond Alberta as a leader in the UCVM/Cumming School of Medicine One Health Field School that takes place yearly in May/June in Tanzania. He works with veterinary students as part of their rotation in an interdisciplinary team to improve the livelihood of the population that primarily depends on livestock for their survival.

Presentation Overview: In his presentation Frank will discuss how enzootic Bovine Leukosis is a problem that almost every dairy farmer recognizes. In the recent past this disease was dismissed as having hardly any impact on productivity, however, we now have evidence that BLV does negatively influence cow health and milk production. The good news is that it is possible and profitable to control or eliminate BLV from your herd.
