This webinar is intended to familiarize the poultry industry as well as research institutes around the world with the Optimum Vitamin Nutrition (OVNTM) concept. This concept was introduced as an efficient means to optimize poultry health and performance which can also directly influence the quality and nutritive value of their products for human consumption. Research has demonstrated that following OVNTM recommendations for dietary supplementation of both water- and fat-soluble vitamins can result in beneficial effects on birds well-being and production variables under practical poultry farm conditions. 


This webinar will broadcast at:

  • 9:00 AM Central (Chicago)
  • 4:00 PM CET (Zurich)



  • The benefits of OVNTM supplementation in modern poultry production
  • How OVN™ ensures animals receive the level of vitamin supplementation necessary to allow them to produce to their potential, while remaining healthy.
  • How Hy-D®, the highly effective 25-OHD3metabolite of vitamin D3, has a role in numerous functions such as supporting a healthy immune system.


This webinar is sponsored by DSM and presented by WATT Global Media


Speaker Info:

Ramesh headshotDr. Ramesh Selvaraj, professor at Ohio State University, associate editor of Poultry Science

Dr. Ramesh Selvaraj was born in India and received his DVM and MS degree from Tamil Nadu Veterinary and Animal Sciences University, second MS degree from Oregon State University and his PhD degree from University of California, Davis in Immunology.  After a postdoctoral research associateship at St. Jude Children’s Research Hospital, at Memphis, TN, he joined The Ohio State University as an Assistant Professor in 2007. Selvaraj’s laboratory is the first laboratory ever to identify and characterize chicken T regulatory cells. T regulatory cells are a subset of T cells specializing in immune suppression and are involved in microbial defense, pathogen persistence, impaired vaccine responses, and compromised anti-tumor responses. A comprehensive understanding of T regulatory cells is critical not only for understanding host-pathogen interactions during infections, but also for vaccine design and development. Chicken T regulatory cells were isolated based on CD25 marker. Because anti-chicken CD25 was not available commercially, Selvaraj’s laboratory made a monoclonal anti-chicken CD25.

Selvaraj has published approximately 35 refereed papers. He teaches Nutritional Immunology in Animal System to graduates and undergraduates at The Ohio State University. A PSA member since 2001, he has regularly served as section program chair and judge of student presentations at the annual meetings. He is also serving as an associate editor of Poultry Science (Health and Disease) and frequently reviews manuscripts for other journals in his specialty area. 


Levy headshotDr. April Waguespack Levy, Technical Support Manager for Poultry, DSM

Dr. April Waguespack Levy holds a M.S. and Ph.D. in Animal and Dairy Sciences from Louisiana State University, where her focus was the feeding of low crude protein, amino acid supplemented diets to broilers and pigs. She is currently a Technical Support Manager for Poultry at DSM where she specializes in vitamins and enzymes. Prior to DSM, her work focused on organic acids, minerals, and antioxidants in the U.S. poultry industry. Dr. Levy is an active member of both the Poultry Science Association and World Poultry Science Association. She has 9 papers in peer-reviewed journals.

Dr. Guillermo Zavala is the founder of Avian Health International

Dr. Guillermo Zavala is the founder of Avian Health International.  Dr Zavala holds a DVM and a specialty in poultry production from the University of Mexico; a Master of Science, a Master of Avian Medicine, and a PhD in medical microbiology from the University of Georgia. He has worked in broiler and breeding companies, vaccine companies, one diagnostic laboratory, two academic institutions and as Adjunct Professor at the Department of Population Health, University of Georgia. His field of research is in applied virology (CIAV, IBDV, tumor viruses, ILT, enteric viruses and fowl adenovirus). He has 32 publications in peer-reviewed journals.
