Background: 19 year old TB in moderate work, Dressage, Jumping, occasional Hunter Pace or XC. Summer in Georgia is always especially hard on his weight, but he is noticeably lacking in topline this summer although excelling in dressage lessons and muscling elsewhere.
Feed/Turnout situation: In for appx 10 hrs per day, during the peak time of heat. Free choice coastal bermuda and 2-3 flakes of Alfalfa while in stall. Plentiful grass during remaining hours of the day turned out (12-14 hours). Currently eating 8lbs per day of Triple Crown Senior, as well as a daily electrolyte (Kentucky Performance).
My question: Would it be worth feeding a ration balancer as a supplement for added protein to enhance topline? I am worried about selenium overdose, which I’ve read is a real risk when going for RB in addition to a complete feed.
Alternative suggestions are welcome. I will be consulting with my vet as well. Have toyed with the idea of adding Tri Amino or Omega Horseshine, but have not acted on it. Also intrigued by the muscle specific supplements by smartpak or cavalor.
Thanks in advance!
