When I said little to none, Mine only get grain as a treat once in awhile and then ONLY a Handfull they just do not need grain and I am sure that article means little as 1/4 cup of grain just a small amount 2 times a day....After all mini donkeys only wiegh between 150 and 225 lb's they just IF in good shape, and not in foal, just only need some as a treat but not everyday even at that, IMO... But if you need to put wt on or the jenny is PG then yes a 1/4 to 1/2 cup a day but idle and in good shape donks don't need any..Only as a special treat.
