Lactobacillus fermentum - Feed Ingredient

Lactobacillus fermentum is a species of lactic acid bacteria commonly used as a probiotic in animal nutrition. It is a Gram-positive, facultative anaerobe that ferments carbohydrates to produce lactic acid. In equine feed and supplement formulations, L. fermentum is included to support gut microbial balance and maintain a stable intestinal environment.

This probiotic is typically added in a freeze-dried form to ensure viability during feed processing and passage through the stomach. It may be included alone or as part of a multi-strain probiotic blend. The intended function is not nutritional but microbial—helping to stabilize the gut microbiota, especially during periods of stress, dietary change, or antibiotic use.
