The Nutritionist 2017

Upcoming and Archived Webinars

Most two-hour sessions are held the second Wednesday of the month. There is slight variation; attend to the specific talk date. A complete recording of each seminar will later be posted here and on the 3rLab websites. Pre-registration is required. For more information and registration, contact webinars@agmodelsystems.com

Our 2017 webinars are co-hosted by  Paula Turiello in Argentina and 3Rlab in Brazil by Marcos Neves Pereira; the primary host is Mariann Fessenden in English for AMTS. The webinar would not be possible without the generous assistance of Ajinomoto Heartland, Arm & Hammer Animal NutritionDairyLand Lab, Dairy One Forage Laboratories, R&D Life Sciences, Adisseo, AminoMax, Jefo, and QLF

Fiber, Fill, and Fermentability—What determines Feed Intake of Dairy Cows?

Dr Barry Bradford is professor of Metabolic Physiology in the Department of Animal Sciences and Industry at Kansas State University. He oversees a diverse research program focused on interactions of inflammation and metabolism, signaling effects of nutrients, and novel approaches to formulation of dairy cattle rations. A Fulbright scholar, he recently completed a sabbatical in Australia he worked on a next-generation approach to pharmaceuticals known as RNA interference.

Larry Chase, March 8, 2017 5:00 pm EST

Cows, Gases, and the Environment

Dr Larry Chase has been involved in Dairy Nutrition at Cornell since 1975. His focus has been in extension and outreach. Larry’s expertise in efficiencies and sustainability has been used to improve nutrient use in rations and decrease excretion into the environment.

Mark Hanigan, April 5, 2017 1:00 pm EDT

Economic considerations of Ration balancing and Nitrogen Metabolism

 

Dr. Mark Hanigan joined the Dairy Science Department at Virginia Tech in 2005. His research is focused on animo acids and nitrogen with a strong emphasis on improving animal efficiency and reducing the effect of food animal production on the environment. Mark’s talk will incorporate economic considerations into ration balancing. Note the time and date variation form the norm for an Eastern Hemisphere friendlier time.

Ian Lean May 10, 2017 6:00 pm EDT

Nutrition of the Transition Period and the special challenge of Pasture at this time

Scibus founder and managing director, Ian Lean is a leading authority in the medicine, nutrition and management of dairy cattle. Between 1986 and 1996, Ian lectured in clinical nutrition and cattle medicine at the University of California and then the University of Sydney, where he remains an Adjunct Professor in Veterinary Clinical Studies. Ian is the author of than 200 scientific articles, many of which have been published in internationally-renowned journals, as well as the university text, Nutrition of Dairy Cattle. He has appeared as a keynote speaker at major conferences in Australia, New Zealand, USA, Canada, UK, Argentina and South Africa.

Sam Fesssenden, June 7, 2017 6:00 pm EDT

Integration of existing On Farm data collection systems into nutrition models

Dr. Sam Fessenden joined AMTS in October 2016 shortly after receiving his PhD from Cornell University where he focused on the CNCPS model and nitrogen metabolism. His talk will focus on strategies for incorporating existing on-farm data collected from sources such as dairy records, cow tracking software, and feed management programs into nutrition models for efficient sharing of information and more accurate ration balancing. Please note the date.

Dale Bauman, July 12, 2017 6:00 pm EDT

Diet Induced Milk Fat Depression: Rumen-derived Fatty acids as Regulators on Milk Fat Synthesis

Dr Bauman is one of the most noted researchers and teachers in the area of dairy cattle nutrition and feed efficiencies in the world. His research has involved the integration of nutrition, endocrine, and biochemical metabolic regulation. Since his cessation of formal teaching responsibilities at Cornell University in 2010 he has focused on many things one of which is being active participant in providing science-based information for public discussion and interactions with policy makers regarding current issues in science and animal agriculture.

Christian Cruywagen

Christiaan Cruywagen, August 9, 2017 1:00 pm EDT

Challenges to maintain a healthy Rumen pH in Dairy Cows

Chrisiaan Cruywagen is a professor emeritus in animal nutrition in the Department of Animal Sciences at the Stellenbosch University, South Africa.  After working for the Department of Agriculture as research scientist for 21 years, he joined the Stellenbosch University in 1996. His talk will focus on maintaining healthy rumen pH and cover some information for those with cows on pasture. Please note the time change from normal.

Lance Baumgard, September 13, 2017 6:00 pm EDT

Leaky gut’s contribution to heat stress and Ketosis

Lance received his B.S. and M.S. degree from the University of Minnesota and a PhD from Cornell University.  He joined Iowa State University in 2009 as the Norman Jacobson Professor of Nutritional Physiology in the Department of Animal Science. Baumgard’s primary research emphasis has been on the metabolic and endocrine consequences of heat stress in growing and lactating animals. At Iowa State University, Lance’s Environmental Physiology efforts have evaluated how heat stress alters post-absorptive fuel selection in growing and lactating farm animals. He also focuses on the mechanisms that govern nutrient partitioning during the transition period of lactating dairy cows.  His primary goal is to identify nutritional strategies that can improve productivity and production efficiency in monogastrics and ruminants.

Michael Ballou, October 11, 2017 6:00 pm EDT

Systematic approach to improving immunity in periparturient dairy cows

Dr Michael Ballou joined Texas Tech University Colleges of Agricultural Sciences and Natural Resources as a nutritionial biologist and associate professor where his research has centered on understanding how the innate immune responses of animals at various physiological states are involved in resistance to diseases and how those responses can be regulated through management and nutrition practices. His talk will be the first of two focused on this subject.

Heather Dann, November 8, 2017 5:00 pm EST

Milk Analysis and The On-farm use for Management Decisions

Heather Dann is a research scientist at the William H. Miner Agricultural Research Institute in Chazy, NY where her research has focused on dairy cow nutrition and management. In particular, she has investigated different types of diets for transition cows to help control feed costs and minimize environmental concerns while promoting animal health and productivity. Also, she has examined management factors important for animal welfare including stocking density and maternity pen design and management. Most recently, she is looking at ways to use milk analyses for real time management decisions.

Register for the Webinar

The series is a unique, three language presentation held in English, Portuguese, and Spanish.

Noted ruminant nutritionists present in English hosted by Mariann Fessenden of AMTS in the United States; Marcos Neves Pereira hosts a simultaneously translated webinar in Portuguese, and Paula Turiello hosts a Spanish language webinar.
