Helps horses overall health and condition including attitude
easy to feed this product to make sure they get those probiotics. Nice price on S&S too.
We have been using 707 products for many years. Our horses that are 25+ years have no digestive issues and our vet is impressed.
Using under 707 recommendations because we lost a horse due to colic.
Live your products. Am using several and they work amazingly. Thank you
From FWC (fecal water synonym) to perfect road apples within 2 weeks. So nice to have a clean tail.
The mare never really had a dietary or digestive issue. As she ages, we thought it couldn't hurt.
My horses do so well on it!

Today, we continue his legacy with a full line of innovative products to support every horse.
