David Pugh, DVM, MS, Dipl. ACT, ACVN, of Auburn University, spoke at the AAEP's Horseman's Day on Geriatric Nutrition. He said a geriatric is a horse over 20 years of age. "Just like us when we age, horses have problems," said Pugh. "Horses' intestines, eyes, and so on wear out. Because of the care people are providing, the potential exists for a horse to live into its 30s and 40s. I know of one stallion who is 45, and they still collect (semen from) him!"

Pugh said a body condition score tells us a horse's long-term energy intake. "I want a horse at 5-6 on a 1-9 scale," he said. "By definition, a 5 is a horse I cannot see the ribs, but I can feel them.

"Every geriatric needs an oral exam twice a year because of potential molar loss," said Pugh.

Feed for geriatric horses needs to be easy to chew and swallow. Choke is a major problem. Feed also needs to be palatable, dust-free, and provide enough energy to keep the horse at a body condition score of 5 or better. While older horses need protein, crude protein levels shouldn't exceed 12-16%. Make sure there is enough fiber for normal gut function, with adequate vitamins and minerals. (See article #4983
