摘要：This study aimed to evaluate the effects of a supplement that contains resveratrol and hyaluronic acid (RH supplement) in aged lame horses. A total of 16 horses of both sexes, aged between 15 and 22 years, weighing between 350–450 kg and showing lameness due to arthritis of the knee, hock, stifle, and fetlock joints and stiffness owing to ageing were used for the study. They comprised eight horses that were administered the RH supplement for three weeks and eight others that served as controls and were given only a Saccharomyces cerevisiae yeast strain used as carrier in the supplement. Blood samples were collected from each horse before supplementation (week 0) and at weekly intervals for the three weeks of the experiment. Biochemical parameters including creatine kinase, aspartate aminotransferase, urea, glucose, total cholesterol, sodium, potassium, chloride, and calcium were measured by standard methods. There was a significant (P˂0.05) reduction in values of creatine kinase and glucose in the horses administered the RH supplement. It was concluded that the RH supplement may reduce the level of these biochemical parameters and their deleterious effects especially during ageing in horses.
