How Soon Should You Change Horse Feed?
The safest answer is usually: not in a hurry. Most horse feed changes should be made over a step-by-step transition of about 7 to 10 days, and sometimes longer for delicate horses. A thoughtful feed change supports digestive health, supports hindgut fermentation, and gives the digestive system time to adjust to new levels of fiber, starch, protein, and calories. Even if the new horse feed looks similar, a sudden switch can still disrupt gut health and cause digestive upset.
