Buying the next pack of a horse supplement is a good time to check the label. A refill pouch can save space in the feed room. A tub may come with a scoop. A liquid can be convenient to measure if its feeding directions suit your routine.Match the name and formula before you refillCheck the full product name, form and ingredient list on both packs. Some ranges offer powders and liquids with similar names. For example, Global Herbs Restore powder and Restore Liquid have separate feeding directions. Use the directions on the pack you are feeding, with the correct scoop for powder or a marked measure for liquid.Compare days of supply for your horseDivide the packs weight in grams by the number of grams you feed each day. For a liquid, use millilitres for both. If the directions have a higher initial rate, calculate those days separately.For example, the label for Airway Plus Powder refill gives a maintenance rate of 22g a day for an average 500kg horse. At that rate, 750g lasts about 34 days. The Airway Plus Powder tub in 1kg lasts about 45 days. The higher starting rate on the label will use the pack faster. Check the weight shown for the option you select.Keep the label with the supplementIf you use a pouch to refill a tub, empty and dry the container first, then keep the pouch label, batch number and best-before date. Store it sealed in a cool, dry place as directed. A pouch such as the Marshmallow Root Powder refill also has its own feeding instructions. Check those each time you switch products, especially if your horse receives other supplements or medication.Review the whole feed routineRead the ingredients of the products you already feed before adding another. Keep a note of the product, rate and date started so everyone who feeds your horse follows the same plan. Ask your vet or an equine nutritionist for advice if youre changing the routine for a horse with a diagnosed condition.
