Horses have complicated digestive systems. Colic is any condition that causes abdominal pain or changes the normal functioning of a horse’s digestive tract. When a horse grazes, it takes in the sand from the ground, this sand builds up along the intestinal tract. When the amount of sand ingested surpasses the amount the horse eliminates, it develops sand colic. Psyllium is a product used to prevent sand buildup. As psyllium moves through the digestive tract, sand attaches to it. When your horse passes the psyllium husks, it passes the sand with it.
Start a plan for feeding the psyllium to your horse after discussing the time frame with your veterinarian. Feed the husks three to seven days once a month following the dosage instructions with the product. Dosage will depend on the weight of the horse. Psyllium should not be a daily additive. It can disrupt the natural digestive processes of the horse.
Place the husks on top of the feed. Psyllium absorbs water and becomes sticky. According to the website Horsekeeping.com, application of psyllium husks on top of the feed keeps it from absorbing too much water before the horse digests it.
Supply your horse with plenty of fresh water during the Psyllium feeding period. Psyllium works by absorbing sand as it moves through the digestive tract. Water softens the husks and enables them to move.
