Novus International Green Acres Research Farm

Green Acres is a 95-acre multi-species, multi-functional research facility operated by Novus International, Inc.

The Overrated Value of Overfeeding Minerals

Trace minerals are essential to optimizing cow production throughout the year. From breeding season all the way through gestation and calving, providing the proper level of supplementation is critical to maintaining a healthy, productive cow.

The challenge for nutritionists and beef producers is that poor trace mineral status, either excess or deficiency, does not immediately impact health or performance. In fact, trace mineral deficiencies can take 60 to 120 days to appear, and nearly as long to fix. It’s important to consistently feed an adequate amount of a bioavailable source of trace minerals to maintain optimal levels of productivity and performance.

Proper trace mineral nutrition can lead to:

  • Enhanced immune system function
  • Reduced morbidity and mortality
  • Improved immune response to vaccination
  • Enhanced reproductive efficiency
  • Improved hoof health
  • Improved oxidative balance
  • Improved carcass quality

The National Research Council estimates that trace minerals such as copper, manganese and zinc have low natural bioavailability and absorption in the animal and must be supplemented to meet requirements. Also, commonly fed by-products, such as distiller’s grains, can contain high levels of sulfur that act as antagonists to minerals, making them less available to the animal.

Trace minerals provided as inorganic salts (sulfates or oxides) are susceptible to antagonists, which makes the trace mineral unavailable to the animal. Formulated supplements may include inorganic salts as sources of zinc, copper and manganese, but much of the trace mineral is excreted and lost to the animal due to numerous chemical antagonisms and interactions with other components of the diet in the digestive tract. This can result in producers spending more than necessary to over-supplement minerals and higher levels of unabsorbed minerals being excreted into the environment. In today’s market place, with margins that are continually shrinking, it is important to consider a trace mineral supplementation option that optimizes production and yields the greatest return.

“Once you meet an animal’s nutritional requirement for trace minerals, the rest is just extra, those extra minerals don’t matter. We actually have seen research that shows those extra trace minerals can do more harm than good.

“The animal’s needs can be easily met with a lower supplemented level of a high quality organic trace mineral. This not only saves the producer money but saves on production losses that can occur from mineral-to-mineral antagonism.” explained Dr. Will Seymour of Novus International.

With a solid foundation in trace mineral nutrition, Novus International offers two different lines of minerals for nutritionists and producers to utilize, MINTREX® and MAAC® chelated trace minerals. Due to the greater bioavailability of both lines of trace minerals, producers are able to supplement cows with a lower total level of trace minerals and still achieve the same, if not better, performance.

Because of the unique chelate structure, which “protects” the mineral in MINTREX and MAAC, their affinity to interact with antagonisms in the diet is essentially zero. This results in a much higher post-rumen availability of the trace minerals, meaning that more is absorbed and utilized by the animal.

Announcing MINTREX® Packaging Change

Novus is pleased to announce a packaging change for MINTREX Zn, MINTREX Cu and MINTREX Mn from the existing paper bag to a new polywoven bag. This change will not affect product prices or specifications but has been rolled out to increase bag quality, strength and longevity.

Product is now being bagged in the new polywoven bags in Little Rock, Arkansas, at our MINTREX plant. Expect to see the new bags in your warehouse over the next two months as inventory of product in the paper bags depletes at our warehouses throughout the U.S.

We apologize if this causes any inconvenience but feel you will appreciate the new bag. If you have any questions about this packaging change, please contact your local Novus sales representative or our customer service team at 800-568-0088.

Novus Is With You When It Matters!

Novus represented our dedication to providing products based in science at JAM 2016 in Salt Lake City, Utah! Several of our Novus researchers presented brand new research during the daily sessions including new research on the possibilities of enhancing reproductive development and performance of beef heifers by supplementing chelated trace minerals presented by Dr. Heather Tucker. Our ruminant sales team was able to discuss with customers, industry producers, as well as students from around the world opportunities for overcoming industry challenges and utilizing Novus products. Celebrating our 25th Anniversary at Squatters Brewery was a great success with our customers and industry partners. Everyone who attended received a Novus JAM Salt Lake City t-shirt in honor of Novus birthday. Getting to share our experiences and passion for the animal health industry with the Novus family for the last 25 years was a great joy. The Novus crew thanks YOU, our customers, for 25 years of business and is looking forward to continuing our business partnership for the next 25 years and beyond.

Getting to Know William Seymour


Dr. William Seymour is responsible for the management of technical support for primarily ruminant team members and independent agents throughout the US. As a liaison among Novus sales, marketing and research teams, he helps train sales staff, develops technical marketing materials and is involved with product development

Prior to joining Novus in 2014, Will managed ruminant and nutrition research as well as provided field technical services for Southern States Cooperative, Inc. He was responsible for multi-species feed formulation and product integrity, and supervised the formulation staff. He also taught professional animal science training programs for the company’s technical services representatives.

Will has held technical marketing management, nutritionist and research roles throughout his 25+ year career at companies such as Roche Vitamins Inc., Tennessee Farmers’ Cooperative and Agway, Inc. He also spent time as a regulatory affairs manager for DSM Nutritional Products, Inc., where he was responsible for U.S. Food and Drug Administration submissions for animal feed additives.

Will is a past president of the American Registry of Professional Animal Scientists and has published several peer-reviewed articles in the Journal of Dairy Science and other publications. He earned his bachelor’s degree in animal science from Cornell University, and his master’s in Dairy Science and doctorate in Animal Science from Virginia Polytechnic Institute and State University while on a John Lee Pratt Animal Nutrition Scholarship.
