I have purchased a purebred Arabian colt that is in the process of being weaned right now and will be coming to live with me in early October. He will be five months old when he gets to Florida and I am trying to figure out the best grain choice for him. My local feed store is a Purina supplier so my main options are Equine Junior, Ultium Growth or Omolene 300. What are your experiences (pro's and con's) for feeding a complete feed like Equine Junior versus a more across the board grain that would have to be heavily supplemented with hay/pasture? Even with a complete feed I would still give a small amount of hay daily and he will have access to the pasture for a few hours each day when the weather permits. Thanks!!
