Four years ago we started looking into new products that might reduce death loss in feedyards, we had two questions in mind:

1) How do we get more from current vaccines and antibiotics?

2) How do we avoid using antibiotics in the bunk?

One of the many unique products we looked at is called beta glucans. The beta glucan molecule is a proven natural immune stimulant taken by humans and fed to livestock.

Beta glucans had widespread use in poultry, swine, and aquaculture. Specifically designed glucans fed to dairy cows in research trials were shown to reduce mastitis (udder infection) by 40%.

We started to search for a beta glucans product that might reduce pneumonia in feedyard cattle.

In all, VeriPrime feedyard members and research veterinarians evaluated over 20 different beta glucan formulations. Plant based, mushroom based, and several yeast derived beta glucans were tested. Some were completely ineffective while others showed promising results.

Final formulations were tested looking for the best improvement of acquired immunity, stimulation of mucosal immunity, and increased effectiveness of macrolide antibiotics.



This paper provides a review of Beta Glucans, the molecule’s chemical and biological properties, role in immunological reactions and a summary of VeriPrime investigations

Beta glucans are stimulators of macrophages, see studies measuring the effect on white blood cell counts of cattle.
