I feed pink powder and with that my mare gets a bit of horsage calmer and some apple cider vinegar (joints) - No hard feed but is on haylage (wish she was on hay though)
My mare is on a forage only feed as she is prone to tying up and she is fed Hay & a small handful of Hoof Kind with Feedmark Benevit Advance, she has kept her weight on, has a lovely glossy coat, bright eyes and good feet.
