Horses and Fermentation

Unlike people and dogs, horses have a diet composed primarily of forage (grass and hay) and have a cecum in the hindgut for the fermentation of these forages. For this reason, a horse is referred to as a hindgut fermenter. The cecum is a large tube-like structure at the junction of the small and large intestine that holds large particles of forage material for fermentation and digestion. Fermentation is the process by which the good anaerobic (without oxygen) bacteria break down plant cell walls and carbohydrates to provide absorbable vitamins and energy sources to the horse. Horses cannot break down these plant cells without the presence and maintenance of the good bacteria in the hindgut and the functional environment for the support of fermentation.

Why does Proviable®-EQ use yeast?

Proviable®–EQ supplies live yeast probiotics as a supplemental source of support for the good bacteria in a horse’s digestive tract. These yeast probiotics support the maintenance and repopulation of these bacteria, and the fermentation process necessary for forage digestion. Proviable®–EQ contains billions of live probiotic microorganisms and is quality tested to meet label claims.

Proviable®–EQ uses yeast because they are more supportive in the anaerobic (without oxygen) environment of the hindgut during fermentation, as opposed to aerobic (oxygen requiring) bacteria used in many other products that support the foregut but may not survive in the hindgut. The yeast probiotics used in Proviable®-EQ support the maintenance and repopulation of the beneficial bacteria in a horse's digestive tract, and the fermentation process necessary for forage digestion.

The Saccharomyces species used in Proviable®–EQ have also been shown to inhibit the growth of some bad bacteria that may result in loose stools, such as Salmonella and Clostridium. When imbalances or stress occur, horses become more susceptible to the growth of bad bacteria and the destruction and loss of good bacteria. Saccharomyces species given prior to or after these imbalances or stresses occur can decrease loose stools and protect against a shift in the bacteria from good to bad thus encouraging the maintenance of healthy and effective digestion.
