Bifidobacterium longum subsp. infantis (B. infantis) is unique among gut bacteria in its immense capacity to digest and consume complex oligosaccharides like those found in equine milk.

B. infantis and L. plantarum are believed to work together in a three-part action:

1. Consume complex carbohydrates found in equine milk

2. Produce short chain fatty acids which help provide extra energy for the foal

3. Support a healthy gut epithelium, the layer of cells that form the surface lining of the small and large intestine in the gastrointestinal tract
