I bought Rosie for my daughter in November as a pony club all-rounder. Rosie would lose condition and become very tucked up the more work she did and the more we traveled to competitions. When I tried to build her up on our usual nuts and chaff she would get really fizzy, not load, spook etc. My vet advised I try Simple System feeds. We haven't looked back. Rosie has maintained her weight, we can feed it to her as we need to. She often eats it in the trailer with lots of water added so she doesn't dehydrate when traveling. My daughter Harriet and Rosie are going from strength to strength. jumping higher and higher . I can't recommend this feed enough. Thank you!
