Excellent results !

My vet had suggested that my horse put on more weight before the winter 1922 . This product worked so well I no longer needed to give it to my horse in the spring . Not to mention this product brought him out of winter with a gorgeous, shiny coat ! I highly recommend , and will probably use it again this coming winter . Which truthfully , I do not want to even think about right now !

Hope it works

This is the second purchase of the same product. First was a smaller bucket used to add weight to a very thin horse. No real result from adding this to his feed the first time. Trying again. Hoping this will work over time.
