Selko, along with Nutreco and Trouw Nutrition, present research

SYMPOSIA session is being held in July in Canada.

Selko and the feed additives brands Nutreco and Trouw Nutrition are set to present their latest research at the co-hosted ASAS-WSASAS BEEF SPECIES SYMPOSIA session during the American Society of Animal Science (ASAS) Annual Meeting from July 21 to 25 in Calgary, Canada. The session will be co-chaired by Prof. Dr. Reinaldo Cooke of Texas A&M University and Dr. Jeff Heldt of Selko U.S., featuring leading academic and industry researchers in trace mineral nutrition.

The Trace Mineral Symposium, scheduled for Monday, July 22, will explore the critical role of trace minerals in beef cattle metabolism and performance. Speakers at the symposium include:

  • Prof. Dr. Jerry Spears, North Carolina State University
  • Dr. Javier MartĂ­n-Tereso, Trouw Nutrition
  • Prof. Dr. John Arthington, University of Florida
  • Prof. Dr. Terry Engle, Colorado State University
  • Prof. Dr. Rodrigo Marques, Virginia Polytechnic Institute & University
  • Prof. Dr. Pedro Fontes, University of Georgia

Dr. Jeff Heldt remarked, “Delegates at the symposium will return home with the most up-to-date view on trace minerals for beef cattle production in the 21st century.”

Dr. Davi Brito, global trace mineral program manager at Selko, highlighted the significant contributions from Selko and Trouw Nutrition, who are Diamond sponsors of the ASAS annual meeting. Over 60 industry professionals, including nutritionists, technical advisors, consultants, veterinarians and researchers, have been invited to share and discuss research findings. Selko and Trouw Nutrition will present 14 research abstracts, including eight at the Trace Mineral Symposium.

Key abstracts include:

  1. Effects of trace mineral source and chromium supplementation on rumen fermentation, growth performance, and carcass characteristics in finishing beef steers.–Dr. Jeff Heldt, Selko & Colorado State University, USA.
  2. Maternal supplementation with different sources of trace mineral and its effects on postweaning responses of offspring.–Vinicius Cruz, Virginia Polytechnic Institute and State University, USA.
  3. Copper, Manganese, and Zinc source and concentration in free-choice mineral supplements. Influence on production throughout three cow-calf production cycles.–Chance Farmer, Selko & Colorado State University, USA.
  4. Effects of particle size and trace mineral source on vitamin A stability in premix.–D. Brito De Araujo, Selko & Masterlab Netherlands.
  5. Effects of trace mineral source on dry matter digestibility of silage and mineral absorption.–Fernando Leonel, Federal University of S. J. Del Rey, Brazil.
  6. Impacts of supplementing sulphate vs. hydroxychloride sources of Cu, Mn, and Zn on heifer growth performance and physiology during feed restriction and high-starch challenge periods.–Philipe Moriel, University of Florida, USA & Jose Luiz M. Vasconcelos, Sao Paulo State University, Brazil.
  7. Dietary guidelines for Zn, Cu, Mn, and Fe in bovines, by integrating net requirements, native dietary occurrence, and homeostatic regulation boundaries.–Javier Martín-Tereso & Jean-Baptiste Daniel, Trouw Nutrition, The Netherlands

Strategic Collaboration

Dr. Javier Martín-Tereso, ruminant R&D director at Trouw Nutrition, emphasized the strategic collaboration with academic partners to advance the understanding of trace minerals in animal health and performance. “Our collaborations with partners at research institutes and across the beef industry help us better define the role of trace minerals and other additives in animal health and performance,” Dr. Martín-Tereso stated.
