My Favorite Mule is a Hinny! - Part 3

Part III. My favorite hinny!

It is my belief that there are more hinnys in the mule world than we realize because we typically group hinnys and mules together at shows. I often wonder how many times hinnys are sold as mules and the buyer is not told in fear they will not buy the animal. We bought our first hinny a year or two ago and when purchasing the hinny, which we believed to be a mule, the seller told us before paying for him that the mule was a hinny and did we still want to buy him. The seller informed us who raised the hinny and that he was by a Rocky Mountain Saddle Horse and by a mammoth jenny. We still purchased him and he's been a very unique and wonderful hinny (see photos of James Dean). James Dean like several of the hinnys I have seen has a bald face. Of the few hinnys I have seen all have had some type of unusual star or markings that seem to be less common in mules.

Due to the fact that many people do not register their mules and animals change hands, and information is lost along the way, there are probably more hinnys around than we think. For example, twelve years ago I met a legendary mule trainer, who I consider to be one of my heroes, Walter Nunn, from Bryan, TX in Bishop, CA. He was riding a palomino mule, named LeMoan, that was fantastic on cattle and his friend Kathryn rode her in the reining and she was awesome! Twelve years later, I found out that one of my favorite mules, LeMoan, is not a mule! Until recent correspondence with Dr. Tex Taylor, who clued me in on LeMoan being a hinny, I had always thought LeMoan was a mule and I was bound to find out for sure!

Well, I didn't exactly know how to get in touch with Walter so through a friend (Tina Varga) I got Kathryn Bradley’s email. Kathryn is a great friend and traveling companion of Walter’s and I knew she would know for sure if LeMoan was a hinny and how to get in touch with Walter. I got the answers to both! Walter Nunn impressed me again, with the fact he has email and emails, not to mention he was also inducted into the Hall of Fame this year at Bishop Mule Days (2007)! He emailed me back and said "yes, LeMoan is definitely a hinny." For years I thought my favorite mule was a mule but nope she's a hinny! I studied the photos that Kathryn had sent me to see if I could tell any physical differences when comparing her to a mule and I could not. After finding out that LeMoan was a hinny I was curious to know more from Walter about raising and training hinnys. When I asked Walter about how many times he had to cover his jenny with the stallion, he replied, "I turned the stud in with the jenny and her bred her once or twice." It was a normal breeding schedule, the stallion was turned in with the jenny and she was bred once or twice and then she had a hinny! Unfortunately, Walter has not had any more hinnys and he has tried to rebreed LeMoan's dam but no luck. I was also interested in knowing if the gestation length is similar to that of a mare carrying a mule. A lot of our mares typically carry the mule foals 11 ½ months but I wondered if it would be the same or different if the jenny (since the donkey's gestation length is twelve months compared to the mare's being eleven months) was the mom. I did ask Walter but he couldn't remember.

I was also curious to know from Walter if training a hinny is similar to training a mule or more like a donkey. The hinny we own, James Dean, is super gentle but he was already broke when we got him so I missed out in terms of witnessing how he was started and how he reacted. Walter responded in his email, "LeMoan had a few donkey moments of just sulking up and not going forward and then she got over it." I think her multiple world championships in roping, cow working, cutting, and team penning speak for themselves! LeMoan and Walter Nunn are quite famous and are known from coast to coast for their many accomplishments in those events but I wonder what people will say when they find out like me that their favorite mule is a Hinny! Will this make more people want a hinny and then attempt to breed for hinnys?

I would like to know how many other mules are not mules but hinnys that are showing. I do know another hinny that has done quite well in the show ring. She's a beautiful, true tobiano, sorrel and white, 16 plus hand, hinny owned by Kick Ass Mules in Truth or Consequences, New Mexico. This hinny has been shown throughout the country by Sandy Dove and she too has done outstanding. This hinny will catch your eye if you have never seen her! I have tried to contact Sandy to get some photos but I have not been able to do so. I do know that they have tried to raise more but I believe the hinny’s sire that was a paint horse passed away. This hinny like LeMoan is quite special and well trained. I was always impressed with this hinny because to me she was extremely "horsy" she moved more like a horse, more forward and correct, she seemed to have less resistance and more balance as she tracked.

If you have any experience raising hinnys please contact me because I would like to learn more about them. I truly believe there are more hinnys at our shows than we realize and it would be interesting to learn more about the challenges reproductively in trying to produce them, train them, etc. Dr. David Pugh did mention that when treating hinnys with sedatives that it's recommended to administer a dose more similar to what you would give a donkey and the dosage of a sedative for a mule should be administered closer to that of a horse. Again, these suggestions from a veterinarian are facts that need to be known and practiced by all that own these animals. These suggestions also raise more questions in my mind such as feeding hinnys vs. mules vs. donkeys. If administering medications is different for each hybrid because their body's metabolism is different these are topics that should be researched more. Our manmade hybrids continue to intrigue us all and there is still so much to learn from them! I look forward to your comments and feedback about hinnys; you can email me at amule@bellsouth.net or mcleana5@msu.edu, or send information to Amy McLean 1284 Anthony Hall, Animal Science Department, Michigan State University, East Lansing, MI 48825. I will also be at the following shows this summer, Bishop Mule Days, Bishop, California and The Great Celebration Mule and Donkey Show, Shelbyville, TN look forward to hearing from y'all!
