This best product for added hydration!

I absolutely love replenimash! I actually add more water than whats said to the mash to make it extra soupy for my guys just for added hydration on the super cold

I absolutely love replenimash! I actually add more water than whats said to the mash to make it extra soupy for my guys just for added hydration on the super cold nights.. they love the taste of it and will drink every last drop! I have 2 horses, a picky mini, and a donkey who all very much so enjoyed it. I love that theres no added corn and that it has beet pulp and seaweed derived calcium which has been known to help horses with ulcers. This is a staple in your barn to help prevent dehydration on those super hot or really cold nights.

Picky Eater Loves It

My gelding is older, and he’s not the pickiest eater ever, but he has his opinions. The weather has been up and down and it gets a little concerning when he doesn’t want to finish his feed. He can’t pass this stuff up though and it’s been a great tool to have around for those days. I’ll definitely be using it if we go to any overnight shows this year to make sure he stays in good shape.

My horse loved the flavor of this and licked her feed dish cleaned! This mash is relatively finely ground and needs to be soaked before feeding. It’s easy to scoop out and use as a topper to her other soaked pellets and supplements.

I LOVE Replenimash. I use it a lot in the Summer at shows: during hauling to encourage water drinking, at shows if they don't like the water, or after XC when I want to rehydrate them. I simply add it to water and make it really soupy, they love it.

Great for picky eaters or bad drinkers !

My horses absolutely love this stuff! I’m going to start using it year round to help promote drinking during the colder months, as well as make sure they drink enough
