More Than Just Colostrum! Newborn foals require much more than colostrum for optimal health and protection. Foal Response has been formulated to provide newborns with the optimum Immediate Care Nutrition that they need. Colostrum has been long-studied for its positive effects on the intestinal tracts of newborns, but colostrum is only one piece to the "puzzle." Probiotics have long been recognized as an important factor in gut health, and Foal Response provides the live microbials (probiotics) that may be missing in your foal's gut at the time of birth. The KPx Colostrum and probiotics found in Foal Response, along with other essential nutrients, make Foal Response an ideal supplement for newborns, older foals or weanlings.
