Equine America Sand-Out Digestive Supplement for Horses

  • Powder » 2.6kg Tub £36.49


Soil and pasture vary greatly throughout the UK. If a horse grazes on a sandy pasture, small amounts of sand and dirt will inevitably be ingested which, over time, may build up in the gut.
Sandout should be fed for one week each month to horses or ponies grazing on sandy pastures. A veterinary surgeon may also recommend Sandout in other situations, and will advise accordingly.

Important note: Do not add to wet food, or allow to soak up moisture. Ideally mix into feed immediately before feeding.

Sand out

17th Jan 2017
Timothy Flint
  • VioVet Customer Since: April 2015
  • From: Derbyshire, United Kingdom

My horse has had recurring colic. After severe attack was diagnosed with possible sand colic. She's been free of colic for 5weeks now. We have used the sand out as prescribed by vet. Two weeks 80grams twice daily . a week off then back to the two weeks on. 80 grams twice daily. Would it be advisable to continue using it at a maintenance level. If so how much should I use and how often.

  • Veterinary Advisor

If your horse is grazing on sandy pasture then it would be a good idea to continue with sand out. You could discuss with your vet also but I would recommend feeding for 1 week each month at 80g twice daily.

What is in sand out other than psyllius

does the horse require magnesium sulphate with this product for it to work
what about using a probiotic such as in product assure

thank you

  • Veterinary Advisor

Sand-out contains Psyllium seed husks, Bentonite and Sodium Propionate but no Magnesium Sulphate as far as I am aware. It doesn't need to be fed with a probiotic or magnesium sulphate in order to be effective but can safely be fed with either. Feeding your horse a probiotic is always a good idea to help maintain healthy gut function as suggested with the Assure products. You should not need to add any oil or other type of lubricant- once in the gut it will take on a gel like consistency that will lubricate the gut.

How big are the particles?

13th Feb 2014

My horse chokes and can only eat soaked nuts, no hay or chaff. Can standout be mixed in wet feed?

  • Non-Executive Director

This product can be mixed in wet feed to make it easier to swallow. It is always important to mix the food thoroughly, to ensure that there are no dry pockets of food within the bucket. Then it should not be a problem. It is better to make it slightly over-moist than a bit dry for sensitive horses.
