Hi wonderful people. My 2 year old had a colic episode, and thankfully is fully mended. Doc put him on an equine senior mash during recovery. Doc suggested Purina Mini pellets as a supplement to provide needed minerals which are lacking in my local area (selenium, copper, magnesium?). I read the feeding guideline on back of feed bag, and am amazed how much Purina suggests feeding. Both my 17 year old mare and the 2 year old gelding are in great body condition, and I don't want to get them chubby. Currently, feeding about 2 and a half flakes of grass hay between them, and a small handful of the purina mini grain morning and night. Purina suggests 3 pounds of hay for the mare and slightly less for the 2 year old, PLUS up to 2 pounds of their grain daily. Am I nuts, or is that WAY too much? Thanks! Doc said follow the guidelines.
