My grand prix horse was lethargic on the feed and pink mash, it turned out the pink mash was causing a blockage. In 10 years of owning the horse he had never ever coliced not even once but he coliced twice on this feed in the space of 2 months. He need a week in the hospital as he had two blockages. thankfully since removing off the feed he is back to his normal self. Be very cautious of this feed.
