Could your trace mineral program be doing more harm than good?
Dr. Sara Kvidera, Technical Manager, Micronutrients kicked off the afternoon of presentations with a talk that emphasized the importance of stability, palatability, bioavailability, and digestibility while evaluating trace mineral programs, concluding that hydroxy trace minerals provide more predictability in diets than sulfate trace minerals.
Current concepts in fiber digestion: Focus on source of forage and trace minerals
The second presentation contributed by Michael Miller, Research Technician, W. H. Miner Institute, focused on a study examining corn silage hybrid and trace mineral source. His research determined that cows fed hydroxy trace minerals had higher feed intake compared to cows fed sulfate trace minerals. Furthermore, Mr. Miller’s study found increased total tract fiber digestibility in cows fed hydroxy compared to sulfate fed cows.
The effects of low feed intake on gastrointestinal function
Dr. Greg Penner, Associate Professor, University of Saskatchewan, also talked about the results of low feed intake, and even brief periods of feed restriction and how this can lead to compromised barrier function of the gut and make cows more susceptible to ruminal acidosis.
The causes and metabolic consequences of leaky gut
Closing out the afternoon of speakers was Dr. Lance Baumgard, Iowa State University. He presented about the many factors that can induce leaky gut: heat stress, transition stress, and feed restriction leading to immune system activation and energy directed away from productive performance. He observed that hydroxy trace minerals had been shown to reduce inflammation and improve gut morphology during feed restriction challenges.
Hydroxy trace minerals are specialty trace minerals that, due to their unique chemical structure, improve the stability of premixes and feeds. Micronutrients is the market leader for hydroxy trace minerals marketed under the global brand name IntelliBond. Based in Indianapolis, Ind., Micronutrients is a global mineral feed ingredient producer focused on developing, manufacturing, and marketing a full range of quality trace minerals.
