Do you know the first signs your horse’s digestive system is in danger? Diarrhea, upset stomach, or the worst scenario — colic — can all be caused by changing from one type of forage to another too quickly. Whether it is moving barns, moving to a new batch of hay from the supplier, or switching from a lush, moist, grassy paddock to a dry sandy sacrifice paddock and dry hay, the importance of switching forages slowly cannot be overstated. An adaptation period of 10 to 14 days to transition new feeds into your horse’s diet is recommended.
