As a horse owner, you know that your horse's digestive health is essential to its overall well-being. Digestive supplements like probiotics and digestive enzymes can help support your horse's digestive system and promote better nutrient absorption. Probiotic supplements, in particular, have become increasingly popular in recent years for their ability to help maintain a healthy gut microbiome.
When choosing a probiotic supplement for your horse, it's important to consider the specific strains of bacteria included in the formula, as well as the overall quality of the product. Look for a probiotic supplement that contains a variety of beneficial strains, such as Lactobacillus acidophilus and Bifidobacterium animalis. Additionally, you'll want to choose a product that is backed by scientific research and is effective in supporting the digestive health of horses.
In addition to probiotics, digestive enzymes can also be beneficial for horses. These enzymes help break down complex carbohydrates and proteins, making it easier for your horse to digest their food. When choosing a digestive enzyme supplement, look for one that includes a broad range of enzymes, such as amylase, protease, and cellulase, to ensure comprehensive digestive support.
How to Find the Best Probiotic for Horses
Here are the key points on how to find the best probiotic for horses, along with probiotic and prebiotic supplements, and beneficial bacteria:
Probiotic supplements should contain a high number of live and active bacteria per dose, typically in the billions. Look for a supplement that contains a variety of bacterial strains, such as Lactobacillus acidophilus, Bifidobacterium bifidum, and Streptococcus thermophilus.
Make sure the supplement is designed specifically for horses, as supplements designed for other animals or humans may not be suitable. Consider the form of the supplement, such as powder or paste, and how easy it is to administer to the horse.
Prebiotic supplements should contain a variety of fiber sources, such as beet pulp, alfalfa meal, and soy hulls. Consider the amount of prebiotics in the supplement, as some may contain more or less than others.
Make sure the supplement is designed specifically for horses. Consider the form of the supplement, such as pellets or powders, and how easy it is to administer to the horse.
Beneficial bacteria for horses include Lactobacillus acidophilus, Bifidobacterium bifidum, Streptococcus thermophilus, and Enterococcus faecium. Lactobacillus acidophilus helps regulate the pH of the digestive tract and aids in the breakdown of food.
Bifidobacterium bifidum supports the immune system and helps prevent harmful bacteria from growing in the gut. Streptococcus thermophilus aids in the digestion of lactose and helps break down food into simpler components. Enterococcus faecium supports the immune system and can help prevent diarrhea in horses.
Overall, it's important to consult with a veterinarian to determine the specific needs of your horse and to find the best probiotic and prebiotic supplements for their digestive health.

Buyer's Guide
How do you evaluate probiotic potency in a horse supplement?
Here are some common methods:
Colony Forming Units (CFUs)
This is a standard method for measuring the concentration of viable microorganisms in a supplement. The CFU count represents the number of live bacteria in the product that can reproduce and form colonies. The higher the CFU count, the more potent the probiotic.
Microbial viability
The viability of the microorganisms can be tested by culturing them under specific conditions to ensure that they are still alive and active.
DNA analysis
DNA analysis can be used to identify the specific strains of bacteria present in the supplement and confirm their potency.
Clinical studies
Clinical studies can be conducted on horses to evaluate the effectiveness of the probiotic supplement. The studies can measure parameters such as digestive health, immune function, and overall well-being to determine if the supplement is effective.
It is important to note that potency is just one factor to consider when evaluating a probiotic supplement. Other factors such as strain selection, stability, and delivery method should also be taken into account when choosing a probiotic supplement for horses.
