Introduction
Horses can be affected by Equine Polysaccharide Storage Myopathy (PSSM). This is a debilitating and common muscular disorder. This condition results from an enzyme deficiency that causes large amounts of polysaccharide material to be deposited in the muscle fibers. This can cause stiffness, pain, and decreased muscle strength and performance. Sometimes, horses may be unable or unable to stand or move due to this condition. PSSM can be controlled with the right treatment and prevention. Horses can enjoy a happy, active life.
What is Equine Polysaccharide Stock Myopathy (PSSM),?
Horses can be affected by Equine Polysaccharide Storage Myopathy (PSSM). This is due to a lack of the enzyme glycogen synthase. It converts glycogen into glucose, which the muscles use for fuel. Lack of this enzyme can cause muscle stiffness, pain, reduced muscle strength, and poor performance. PSSM is common in many breeds but it is more prevalent in draft and warmblood dogs than in ponies.
PSSM Signs and Symptoms
PSSM symptoms can vary from horse-to-horse, but they generally include stiffness, pain, muscle weakness, poor performance, and decreased muscle strength. Horses may become unable to stand or walk in extreme cases. You should also look out for signs such as muscle twitching and trembling.
Diagnosis for PSSM
A veterinarian will usually perform a physical exam and talk about the horse’s history to determine if PSSM has been diagnosed. To determine the severity of muscle damage, blood tests can be done to test for muscle enzymes. To confirm diagnosis, a muscle biopsy can be done to inspect the muscle fibers.
Prevention and Treatment of PSSM
It is important to control the horse’s diet when treating PSSM. The diet should be reduced in sugar and starch, and increased fat. Fat provides an alternative source of energy for the horses. Horses should exercise at a moderate pace and should be closely monitored for any signs of recurrence. PSSM can be treated with supplementation with enzyme glycogen synthase. Your veterinarian should discuss the exact dose and frequency. There are many supplements that may help with the condition such as vitamin E and omega-3 fatty acid, along with carnitine.
Tips to Prevent PSSM
PSSM prevention is best achieved by a healthy diet and regular exercise. It is important to eat a low-fat, high-sugar diet. Regular exercise is important but should not be excessive to stress the muscles. You should also be alert for any changes in behavior and performance of your horse. PSSM is a condition that can be detected early on by your veterinarian.
FAQs about PSSM
What are the symptoms and signs of PSSM?
PSSM symptoms can vary from horse-to-horse, but they generally include stiffness, pain, muscle weakness, poor performance, and decreased muscle strength. Horses may become unable to stand or walk in extreme cases. You should also look out for signs such as muscle trembling, muscle twitching and sweating.
How does PSSM get diagnosed?
A veterinarian will usually perform a physical exam and talk about the horse’s history to determine if PSSM has been diagnosed. To determine the severity of muscle damage, blood tests can be done to test for muscle enzymes. To confirm diagnosis, a muscle biopsy can be done to inspect the muscle fibers.
