Liquid Feed Symposium | September 2015

American Society of Animal Science/American Dairy Science Association JAM | July 2015

  • Novus was a Silver Level Sponsor and exhibitor at this annual event.
  • Due to their experience and highly regarded reputations in the industry, Novus scientists were invited to present information on studies conducted on the mode of action of HMTBa.
  •  Presentations included: Flow of microbial crude protein out of the rumen when dairy cattle are supplemented with HMTBa, Differences in microbial community structure associated with metabolizable protein and HMTBa supplementation when using in vitro and in vivo methods, In situ degradability, rumen bacterial population, and in vitro gas production in cannulated steers fed diets with and without HMTBa, and HMTBa supplementation increases milk fat and decreases synthesis of alternate bihydrongenation intermediates in diets with risk for milk fat depression.


Ruminant Novus Advantage Conference a Success 

Novus hosted its first ever Ruminant Advantage Conference August 24 – 26, 2015, in Little Rock, Arkansas, home to its MINTREX® chelated trace minerals manufacturing plant. The meeting was host to key customers from across the U.S. and Canada. Customers in attendance had the opportunity to tour the state of the art MINTREX manufacturing facility just outside of Little Rock and heard from industry leading speakers in the areas of trace mineral nutrition.  

Dr. Tom Overton from Cornell University discussed the basic needs and requirements for trace minerals and how different sources of minerals, whether inorganic or organic, can affect how the animal performs. He placed special emphasis on research comparing inorganic trace minerals and organic trace minerals showing increases in bioavailability and utilization by the animal.

Dr. Jeff Hall with Utah State University reviewed trace mineral abnormalities and diagnostics in dairy cattle. Dr. Hall shared key information on ways to detect trace mineral deficiencies or excessiveness and offered different solutions for overcoming those challenges if seen. Additionally, he reviewed the normal ranges of trace mineral content in key measurement parameters such as liver biopsy.

Dr. Heather Tucker from Novus spent time talking specifically about MINTREX in the animal and key performance benefits that can be realized. She covered research comparing MINTREX to both inorganic and other organic sources showing benefits against both.

Realize the Hidden Value of MINTREX®   

MINTREX® chelated trace minerals are a proven solution for improving animal performance through trace mineral nutrition. Backed by more than 10 years of science, the MINTREX line is the foundation for Novus’s organic trace mineral platform.

Trace minerals are classified as inorganic or organic. Inorganic trace minerals are often underutilized by the animal due to their low bioavailability. Within the organic trace mineral classification, chelated minerals have a stable and defined structure to also for maximum absorption. MINTREX chelated trace minerals are at the top of their class with a completely verified 2:1 chelated structure using HMTBa as the ligand.

Benefits of organic trace minerals include improved enzyme activity; tissue and structural integrity; immune development and response; oxidative balance; and reduced environmental impact. Research consistently shows that MINTREX can increase reproduction by 7 percent, improve overall health by reducing somatic cell count up to 35 percent, and reduce lameness up to 4 percent when compared to ITMs.

The MINTREX molecule is one of only two AAFCO defined chelated trace minerals available on the market today, featuring unmatched quality and maximum value. MINTREX chelated trace minerals are OMRI listed and are the proven solution for optimal animal performance through trace mineral nutrition.


High Quality Trace Minerals Support Improved Dairy Cattle Reproduction 

By Dr. Heather Tucker, Senior Manager, Ruminant Research, Novus International, Inc.

A major contributing factor to profitability on a dairy is reproductive performance of the herd. As dairy cows move toward more efficient utilization of nutrients for milk production during each lactation, stressors within the environment can reduce cyclicity resulting in poor breed back and increased days open. These alterations in reproductive performance ultimately cost the cow as well as the dairyman. In order to best support optimal performance, nutrition should be a crucial tool in the dairy tool box to improve overall performance.

Optimal reproduction in a herd is not limited to getting cows bred but also includes development of young heifers, keeping cows healthy, minimizing lameness and meeting fetal growth requirements nutritionally. Healthy, non-lame cows remain in production for more parities and can maximize production levels on the dairy. Within a dairy cow ration, trace minerals play a vital role in supporting the factors that contribute to a productive cow.  

A dairy cow’s trace mineral requirements can be influenced by age, stage of production and stage of lactation. For example, dairy cattle are most susceptible to mastitis and other infections during the first three weeks before calving and the first three weeks after calving. Proper attention to mineral supplementation, specifically zinc, copper and manganese, during these times can significantly improve immune function and set the cow up for a successful breeding season later on.

Zinc plays a role in immune development and response, cell growth, hoof and bone health as well as a defense against oxidative stress and damage. Additionally, zinc is important for the production of keratin, which lines the inside of the teat duct and helps keep out microorganisms that can cause mastitis. It has been shown that supplementation with chelated zinc can reduce overall somatic cell count, indicating a healthier, more productive cow.

Copper is crucial to red blood cell health, collagen development and more importantly, reproduction. Like zinc, it can aid immune function and help prevent mastitis and other infections. The reproductive benefits of copper are best realized when a challenge or deficiency is overcome. Correcting a deficiency reduces the number of retained placentas, lowers early embryonic death and improves conception rates.

Manganese is the trace mineral that possibly has the greatest impact on reproduction. While pregnant, lactating cows require more manganese than growing cattle. When a cow is deficient, ovulation is delayed, lower conception rates are observed, and often difficulties occur during calving.

While the importance of zinc, copper, and manganese is well known, evidence shows trace mineral requirements of the animal are not consistently met with inorganic forms as bioavailability differs between trace mineral sources. Further, various stressors increase the requirement of these important minerals and can potentially alter the bioavailability of trace mineral sources. Inorganic sources of trace minerals are often prone to antagonisms when used in increased dose levels, resulting in even lower bioavailability. 

Supplementing the diet with highly bioavailable chelated trace minerals allows the cow to get the most use of the mineral, compared to supplementing inorganic trace mineral sources. Supplying a greater, more useable source of trace mineral, either individually or in combination, will help optimize reproductive performance and tissue formation and development. This demonstrates that it is essential to supply the best source of minerals to the cow.

By having greater bioavailability, chelated trace mineral supplementation supports optimal animal performance. A chelated trace mineral source, such as MINTREX® from Novus International, can ensure a greater supply of key nutrients to the cow to support reproductive performance, tissue development and immune response.

Research was conducted at Spruce Haven Farm and Research Center in New York to evaluate the 305-day performance of cows where the inorganic trace minerals were replaced by MINTREX chelated trace minerals. Use of MINTREX allowed for the overall mineral level in the diet to be reduced due to the greater bioavailability.  With no changes in milk yield of composition this study suggests that a trace mineral source with greater bioavailability, MINTREX, allowed for a reduction in mineral intake that did not compromise the mineral status of the cows or alter physiological functions. In addition, a reduction in somatic cell count throughout the 305 d lactation was observed with MINTREX suggesting that the overall health of the mammary gland was improved. 

More recently, a six-month study was conducted on 27 dairy herds in Central Spain with 2,880 cows fed the same TMR with trace minerals coming from either ITMs alone or a combination of ITMs and MINTREX. Throughout the study, it was observed that cows receiving the combination of MINTREX and ITM had a 30 percent improvement in conception rate and were 1.33 times more likely to become pregnant than cows just receiving ITMs.      

With today’s demands on the dairy cow to be more efficient, optimal trace mineral nutrition is important to ensuring the dairy cow is performing at her peak. To best meet her production requirements, she has to breed back in a timely fashion, stay healthy and not succumb to culling due to lameness and other challenges. Through optimizing nutrition with trace minerals such as MINTREX, she can be best positioned for optimized reproduction and production.
