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.

On the 15 th of August 2016, a 6-month-old colt weighing 118 kg was presented to the large animal clinic of Veterinary Teaching Hospital, Michael Okpara University of Agriculture, Umudike. The colt showed clinical signs including fever, weakness, inappetence, anaemia, tachycardia, dyspnoea, rough hair coat, pale mucus membranes, lacrimation, ataxia and edematous swelling of distal limbs. Rhipicephalus eversti eversti ticks were detected on different parts of the colt's body. Examination of peripheral blood smear showed Babesia caballi within the erythrocytes. Haematological analysis showed a decrease in red blood cell count, packed cell volume and haemoglobin concentration. Administration of imidocarb dipropionate and good nursing care yielded a successful result after two weeks of treatment. It is necessary to control ticks by regular use of acaricide and timely treatment of affected horses in order to reduce the devastating effects of this protozoan disease.

This chapter evaluated resveratrol supplementation on laboratory animals, cats, pigs, horses, dogs, cattle and birds. Resveratrol (3, 5, 4′-trihydroxystilbene) is a stilbenoid, a derivate of stilbene. It is found in some plants such as red grape, grape products, cocoa, peanuts, raspberries, mulberries, strawberry and Japanese knotweed roots. The most important dietary source of resveratrol is red wine, and it is often assumed to be an important factor in the French Paradox, a term used to describe the observation that the French population has a very low incidence of cardiovascular disease, despite a diet high in saturated fats. Research has shown some therapeutic effects of resveratrol ranging from antioxidant, anti-inflammatory, cardioprotective, antiatherogenic, antiaging, antiplatelet aggregation, anticancer, antidiabetic, antitumor, and immunomodulatory activities. In laboratory animals, benefits of resveratrol comprise antitumor effects while in cats it has shown to improve hepatic function. In pigs, the antibiotic and antiviral effects of resveratrol have been illustrated. The anti-inflammatory and antioxidative properties of resveratrol in horses and cattle were also reviewed. The supplement was shown to be useful as an antibiotic and an aid in improving alertness in dogs. Resveratrol also showed to increase growth performance in birds. It is therefore concluded that use of resveratrol is a potent aid in improving animal production and health.
