My oldest mare is 34 years old and wondered what that equals in human years. I found a calculator on line that suggests she is the equivalent of 100 years in human age. She is in pretty good shape structure wise blessed with good bones and joints, but poor teeth and doesn't shed well naturally so she gets her senior pellets as a mash and clipped. She was my best producer and gave me five champions on my show string and passed her outstanding movement. She was very reliable to easily foal and an excellent mother, she came from the Peaceful Valley farm, Mr. Dalton . She was retired from breeding after eight foals years ago, but she still cycles and drives the boys insane. She will not ever be bred again, but I recall someone on here in the past had a very old mare that had a healthy foal when in her 30's. Anyone remember that?
