“Effects of direct-fed microbial supplementation on digestibility and fermentation end-products in horses fed low-and high-starch concentrates”

Fifteen mature Thoroughbred geldings were assigned to trial diets to assess how Direct-Fed Microbials might increase digestibility and reduce acidosis from a higher starch equine diet. The paper relates a higher starch diet to enhanced nutrient digestibility but suggests DFM supplements should be studied in a different diet to assess impact.
