T3, stall runner

[Tivers@aol.com]

By the way--have an interesting problem some of you may have an answer for.

TB racehorse in training. Runs around his stall all day long. Shows a T3 over
100 (last reading 128). Can't maintain weight and is catabolic--despite eating
everything put before him--and we put a lot before him (don't want to cause a
lot of heart attacks by saying how many pounds of grain he consumes).

Is this hyperthyroidism? If so, what do you do about it?
