Equine Products UK Sand Shifter is a technologically advanced compound which encourages digestive health. Containing Psyllium Husk powder, this effective dietary supplement uses the revolutionary bulk forming 100% natural fibre that once in the digestive system, reacts with the sand particles to form a fibrous gel that binds the sand and enables the gut to then shift it, avoiding the development of blockages and their potential complications. Equine Products UK Sand Shifter contains psyllium husk powder, a revolutionary bulk-forming natural fibre derived from psyllium seeds. Once in the horse's digestive tract, psyllium forms a fibrous gel which adheres to the sand particles, preventing them from staying in the gut and causing potential blockages. Its bulk-forming capacity encourages movement by peristalsis, aiding the removal of blockages from the horse's digestive tract. Aniseed flavouring has been added for palatability. Feeding Guidelines: For a 500kg horse, feed 150g of powder for 4-5 days. Once the sand particles have been eased through the gut, the horse may require feeding for a further 2-3 weeks to rid the colon of sand. For horses grazing sandy loams or short cropped grass, feed 50g twice daily for seven consecutive days, once every 3-4 weeks or as directed by your veterinary surgeon. What's in it: Pysllium husk Powder, Aniseed flavouring. Size Guide: Available in a 700 gram tub or 4 kilogram tub.
