Garlic: Feeding garlic as a fly repellent is not a new idea, and works because high sulphur compounds in garlic are released through the skin via natural body secretions such as sweat, producing an invisible barrier that flies find repellent. Whilst they may still be present around the horse, they seldom land on the skin, and this significantly reduces the level of irritation normally seen.
Linseed Oil: Linseed oil is rich in Omega-3 oil and can help in producing a healthy glossy coat, healthy skin and boost the immune system. A horse’s natural diet can be low in Omega-3 so horses often need an additional source to provide these essential fatty acids for optimum health.
Antioxidants: Antioxidants are the body’s natural defence against oxidative damage from free radicals and reactive oxygen species (ROS) produced naturally within the body during immune challenge and in the defence against pathogens and play an important role in maintaining the health and integrity of all the different types of cells within the body. The major dietary antioxidants include Vitamin E and Selenium. Imbalances in pro-oxidant production and antioxidant capacity have been linked to ageing, muscle fatigue during exercise and to a number of diseases in horses (DJ Marlin, CE Dunnett and CM Deaton, 2005).
