light framed horse

Question

light framed horse   Hi sir. Is there any term for a horse that is born with a light frame than the ideal thoroughbred which has a round and deep rib cage? We have a 3 year old thoroughbred filly which is just 370kgs and has a light framed structure which looks like this in the photo I have attached.

Answer
Hi she is a beautiful color. I haven't seen. Many of that color. Most fillies are usually smaller in frame then your colts of the same age. Size in the racing industry doesn't seem to matter.  If she is sound then


She will prob make a good race horse. Thanks ED HESS
