How Probiotics Benefit Horses

PrimaLac Direct-Fed Microbial products are proved to attach to the gut wall and colonize the GI tract. By doing this they help improve overall gut health. The PrimaLac organisms compete for nutrients and attachment sites on the gut wall, as well as produce Lactic acid to decrease the pH in the Small Intestine. These activities make the environment inhospitable for the pathogenic bacteria. That coupled with an improved immune system/response makes for much better overall gut and animal health. The major benefits of PrimaLac are:

  • Improved Intestinal Health
    • More efficient digestion
    • Increases absorption of Nutrients
  • Helps Decrease Gut Problems
    • Colic
    • Scours
  • Improves Hair Coat
  • Reduces the Effect of Stress
  • Improves Performance
  • Environmentally Friendly

Probiotic organisms up close

In the equine species, Lactobacillus acidophilus produces Lactic acid and aggressively attaches to the gut wall. Lactobacillus casei and Enterococcus faecium complement the L. acidophilus by also producing lactic acid, but does so in a wide range temperature and pH. Bifidobacterium thermophilum is found in mother's milk as well as human and animal GI tracts. The combination of these microorganisms make PrimaLac’s multi-strain approach effective in all sections of the GI tract. Helping to prevent intestinal issues as well as improving immunity.
