What is mash exactly? And why do we need it?
Mash is essentially watered down grain. For many it’s as simple as that. Daily grain ration + water + 10 min soak = serve.
However mash can also serve as a fail safe while traveling or camping. It’s a great way to get moisture into your horse instead of worrying at every creek crossing or wondering if they had enough overnight.
Just simply providing and finding a mash that they love- will ensure they drink anytime you need them to. Here’s my basic recipe that supports hydration, forage based diets and the increased nutritional needs during trail season.
- Purina Replenimash – readily available from feed stores, provides the needed electrolytes, and tastes good.
- Vitamin E Capsules – additional 2,000-3,000 IUs during travel and increased work loads.
- Marshmallow Root & Slippery Elm Bark – ulcer prevention.
- Water. A LOT of it. I use 12 gallon flexi tubs and fill them to the brim.
Optional – I add hay pellets for more calories when needed, typically Timothy or Alfalfa.
Once your horse has a mash they love, use it consistently. This is the most reliable way to ensure your horse is drinking well. I know that even on the longest hauls through the hot California valley- Moqui will drink this right through the trailer window. And with that sort of reliability- I feel safer traveling long distances in less than ideal conditions.
For the backcountry- just cut this down to a smaller batch and you have your breakfast mash ready to serve. Add some creek water, your mash baggie and watch them devour it.
