One Size Fits All? Not for Equines

0

An article in the U.K.’s Daily Mail reports that one-third of recreational riders are too obese for their equines, putting the animals at risk for health problems including lameness and back pain, citing a study from the Journal of Veterinary Behavior.

This is a big issue for equine health, as an equine expected to carry a rider that is too heavy for him can cause both physical and behavioral problems. Rules like “the rider’s weight should be 10% of the equine’s” are often used as a general guideline, but are by no means absolute–there are many other factors to consider. Below, Meredith offers her advice in how to choose the correct equine for the rider.

The maximum weight a horse or mule can carry will depend on a lot of variables. Mules and donkeys can carry proportionately more weight than a horse of the same size, because of the unique muscle structure of the animal. However, you do need to be careful about making broad generalizations. Obviously, an equine that has not been conditioned properly will not be able to efficiently carry as much weight as one who has been conditioned properly, so it is all relative to the situation. Also, the rider with better balance and riding ability is going to be easier for the equine to carry than one who is not balanced regardless of the difference in actual weight. The size of the equine and the proportion of the equine to the rider will also affect balance and carrying ability.

The amount of weight an equine can comfortably carry or pull depends on many things, beginning with the animal’s overall fitness. If he is fit, he will be able to carry more than those who are not, but conformational abnormalities will also have an effect. If he has any deviations in his bone structure (i.e. crooked legs), it can compromise how he moves and put undue stress on certain areas depending on the defect. The easiest way to test for weight tolerance is to watch the way the animal moves. If he is halted and seems to be have difficulty moving, the weight is obviously too heavy. If he is unable to trot, or is resistant to trotting, the weight is too heavy. This would be the same in harness. If he cannot move freely, the load is too heavy. So, it’s not just a matter of how old he is, but rather how he is conformed and how fit he is at any given stage of training and the weight and ability of the rider that will dictate how much he can carry, or pull. Be careful about generalizations, because there are always hidden variables to be considered.

For instance, it is commonly believed that an equine should be able to carry 10% of his weight. But if a 2000 lb. animal is carrying the 200 pounds over a back that has not been physically developed correctly, it could be very difficult for him. If he possesses more strength over his topline and through the croup, then he may actually be able to carry more than 10% of his body weight. Any additional weight (as with saddle bags) also needs to be considered. If he is weak over the topline and in his back, then he shouldn’t be carrying even a 150 lb. person, much less anything behind the saddle. The weight does need to be placed and balanced over the bearing areas and the shoulder and hips do need to be kept clear for optimum movement. Anchoring the saddle with a crupper is always a good idea to keep loads from shifting and placement and security of the foundation tack to which you secure all these things needs to be assessed as well. When you add weight to the saddle, check to see if the girth you are using is adequate to keep the saddle in place without rubbing sores on your animal’s body.
