Why Does My Horse Need a Probiotic?

Humans are not the only species that need a healthy gut. Animals of every kind are vulnerable to harmful bacteria in the stomach. Just like humans, a high-quality probiotic is necessary to regulate your horse’s immune system.

For a healthy horse to create the necessary vitamins and minerals needed for good health, all systems must work in harmony to produce healthy enzymes and nutrients. If the digestive tract is off, parts of the horse’s health will suffer.

*Writer’s Tip*

The microbial purpose is to maintain your horse’s live colonies of the good bacteria it needs – That is the lactic acid-producing bacteria that are typically in the horse’s intestines, naturally. It does not take much for the digestive tract to become unbalanced, causing your horse’s health to change.

Enterococcus, Bifidobacterium, and Lactobacillus are the three vital components that can either prevent or reduce the growth of unhealthy pathogens. There are some illnesses, such as Botulism, that can be deadly to a horse.

High-quality fatty acids, enzymes, and vitamins are vital for promoting GI health. Watching for behavior changes in your horse is the first sign that something is “off” with its health. [2]

Yeast and Its Ability to Destroy Horses GI Tract

Yeast is part of the fungus family that can destroy the healthy bacteria in the intestines rapidly. Once that happens, your horse’s behavior and health will change dramatically. While yeast cultures such as yeast extract and active dry yeast, stimulate healthy bacteria growth, a yeast overload can quickly get out of control.

Active dry yeast to be productive must contain fifteen billion live yeast cells for each gram. When you are choosing the best probiotic for your horse, be sure it includes enough yeast cells to be effective.

How to Know Your Horse Needs Probiotics

Horses are like all other species in that their performance and well-being play a considerable role in its healthy digestion. Aside from the barn environment, diet changes, illness, training, and age plays a significant role in its digestive support.

Before you realize there is an underlying issue, your horse’s entire system can fall out of balance. When that happens, the result can be anything from minor problems, such as a bad attitude and dull coat) to significant health concerns.

The following are medical concerns for horses with digestive system disruption:

  • Ulcers
  • Weight Loss
  • Diarrhea
  • Colic

Sixty-five percent of a horse’s immune system is the digestive tract. If the animal has a weak digestive function, it will result in weakened immunity. For whatever purpose your horse serves, providing a probiotic can make all the difference in its health.

Choosing the Right Probiotic

A basic probiotic supplement that provides the horse with the proper dosage is more than enough for most horses. Most supplements such as the ones in this guide will work efficiently in maintaining your horse’s digestive system. The goal of every probiotic is to give the species the right amount of “good bugs” to combat the bad.

However, if you have a horse that is suffering from stress, it is to the benefit of that horse to take a daily supplement. Aside from you supplying the probiotic, you may need to buy a more comprehensive product to best suit your horse’s needs.
