I Just Want To Say Thank You To Koolspeed Feeds…
“I typically run older barrel horses-I guess you might call them seniors-but they don’t act like seniors. Obviously with their age, they require more nutrients, vitamins, minerals, joint supplements, and sometimes ulcer products. I began my feed regiment with Koolspeed feeds over a year ago and have not been disappointed once. I feed the KoolFoal, due to the fact content for my senior horses. I have never had horses that look better. They have a stronger mind and feel their best. Thank you KoolSpeed Feed.
