If you have a grassfed beef program, you may be wondering: Which mineral formula fits your operation best?

Here at Riomax®, we have a couple different lick tubs that may fit into your operation. In this article we'll be discussing a few of the differences between PG360™ (our powerful year-round formula) and GRASS-MASTER360™ (our formula designed specially for grassfed beef operations).   

Which formula best fits your grassfed program?

Similarities between PG360™ and GRASS-MASTER360™  

Both of these products are Riomax® lick tubs, which means they both contain the foundational Riomax® science. This includes Nutrizorb®, a digestion powerhouse, and Esqort®, 100% protected trace minerals. Both PG360™ and GRASS-MASTER360™ include all of the digestion ingredients, minerals, vitamins and trace minerals that your cattle need. Both are foundationally the same, but there are a few key differences that will help you decide which formula makes the most sense on your ranch.     

Differences between PG360™ and GRASS-MASTER360™

The primary differences between the 2 formulas are:

  • GRASS-MASTER360™ is made with non-GMO ingredients
  • GRASS-MASTER360™ does not contain flax. 

If you run a grassfed beef program, you can be assured you aren’t feeding any grains or grain byproducts by supplementing GRASS-MASTER360™.   

American Grassfed Association (AGA) 

We are pleased to announce we have been approved by the American Grassfed Association Riomax® Grass-Master360™ is the first lick tub pre-approved for their grass-fed beef program in the United States.  

Of course, this formula may be used in other grass-fed programs, but the American Grassfed Association is one of the strictest programs.  We are excited to build relationships with those who believe in healthy for people, healthy for animals, healthy for the plant and healthy for communities!

Ultimately, the best protein tub formula for a grassfed beef program is...

...probably GRASS-MASTER360™. If you are after a non-GMO product that doesn't contain any grain byproducts, this is the tub for you! Additionally, because it is approved by the AGA, you can have peace-of-mind that it will align with your grassfed beef operation.
