Add warm water, leave to soak for 5 mins to make a tasty mash, and feed whilst warm (do not use boiling hot water). Cold water can be used to make a mash but leave to soak for 10 mins. Warm water will release the aromas for a more appetising mash. Feed one part mix to five parts water (eg 100g of Ulsa-X – Prebiotic Mash to 500ml warm water). As with any dry feed, be aware that animals that bolt their feed may be at risk of choke. For these animals, soaking thoroughly to make a mash is recommended.
