What’s Fighting Your Phytase?

There are many schools of thought on the relative value of an inorganic source of mineral versus an organic source of mineral. In an inorganic source, the metal is linked with an inorganic element (i.e. sulfate, chloride, oxide), which varies in bond strength. Inorganic trace minerals (ITMs) are often known to be antagonistic within the diet by attaching themselves to diet components like phytic acid, rendering both the inorganic mineral supplemented and the phosphorus bound to the phytate molecule unusable to the animal.

Producers typically supplement phytase to enhance phosphorus release from ingredients making it more available to the animal. However, phytate has a high affinity for the metal anions from ITM supplementation. As a result, before phytase has a chance to have an effect on phytate, mineral-phytate complexes have been formed, limiting phytase effectiveness for phosphorus liberation (Peng and Applegate, 2006). In other words, use of high levels of ITM fights against phytase effectiveness. Adding more ITMs on top of the diet to offset these antagonists is popular due to the perceived relative lower cost of ITMs versus more available chelated mineral sources. However, over-formulating total trace mineral levels arises from this strategy. Choosing a high quality chelated organic trace mineral (OTM) source allows for lower trace mineral inclusion and less mineral excretion.

In OTMs, the mineral is bound to an organic ligand through coordinate covalent bonds. The term “organic” indicates the presence of carbon atoms in the ligand. The strength of these bonds and pH at which they dissociate varies between different types of OTMs. Chelate minerals are considered the most bioavailable trace mineral source on the market. In chelates, the organic ligand is bound to the mineral by coordinate covalent bonds that protect against early dissociation and antagonisms.

By supplementing a highly bioavailable chelated trace mineral, producers can expect the added phytase to be more effective and, in turn, provide more phosphorus to the diet. Efficiently feeding pigs for optimal growth, better feed efficiency and lower mortality is essential for economic return, so feeding a highly bioavailable mineral is imperative.


Industry News Alert > > >

It's clear that the world of pork production is changing rapidly. As a global company, Novus International understands this and has launched a specific program, Project Horizon, to help producers in the US work toward meeting market demand in a sustainable and efficient way. We offer solutions for gut health, feed quality, immunity and much more based on years of research and proven results. CIBENZA® DP100 enzyme solutions support gut health in nursery piglets, SANTOQUIN® feed preservative increases shelf life of feeds that easily oxidize, MINTREX® chelated trace minerals help boost immunity from the sow to the finisher hog and our ACTIVATE® organic acid blends help support positive microflora balance in nursery piglets and can increase performance with or without ractopamine in finisher hogs.

Taking Part in Progress Day836782dd-ff5c-4f90-a098-9a4e9d596c2c

The Novus team had the honor of attending and sponsoring the Keystone Pork Expo and Poultry Progress Day in Pennsylvania. We are proud to support both local, regional and global customers and this expo is one of the many ways we are able to do that. Join us next year!

Getting to Know Dr. Yulin Ma


What is your official title at Novus?
Technical Services Manager, Monogastric. But before I began in this role I worked as a part of the global R&D team in St. Charles as Swine Nutrition Researcher.

How long have you been with Novus?
Six years in February, but it seems like yesterday.

What is your background in the industry?
Swine nutrition by training with focus on mineral nutrition in sows and pigs.

Which product of Novus’s is your favorite?
MINTREX®. The more research I have done on MINTREX, the more confidence I have with MINTREX. I would like to say, if you want to use the best organic trace mineral, MINTREX should be it because it is the best product with tremendous return based on what I have seen so far in the market.

What accomplishment or moment in your career are you most proud of?
My doctorate research on nutrition requirements, specifically minerals, for gestating sows and W-F pigs resulted in five peer-reviewed published articles and five presentations. Another moment was when I received a call from a customer, who kept talking about the benefits he saw with MINTREX, "I was like, the best moment ever."

What is the oddest or hardest question a customer or collaborator has ever asked you?
What is the best product that Novus makes? It’s too hard – we have so many good products!

In your opinion, what is the biggest challenge facing the animal agriculture industry today?
Collaboration and information sharing across the industry.

What would be your first move if you were tasked with helping the industry overcome that challenge?
Next Generation Nutritionist Council was formed across the industry to discuss issues and promote potential collaboration.

When you are not promoting Novus products what do you like to do?
As a fan of Big Blue Nation of University of Kentucky, of course I like to play basketball and watch the NCAA tournament.

If you could go to dinner with any 3 people dead or alive, who would you choose?
George Washington, Chairman Mao and my grandfather.

If you had to choose only one book for your library, what would it be?
A book on World History – it fascinates me.

What is your favorite beef/dairy/pork/poultry product to eat?
Pork chops and grilled ribs.
