L-carnitine in the feeding of sports horses
In horses, L-carnitine is synthesized mainly in the liver from methionine, lysine, vitamins C, B3, B6, and B9 and from Fe2+. L-carnitine plays an important role in the transport of long chain fatty acids into the mitochondria, where they are converted into energy needed for muscle contractions. It also contributes to the accumulation of glycogen in the muscles and prevents an excessive production of lactic acid, ensuring a faster muscle recovery after exercise. The organism of a horse is unable to meet the demand for L-carnitine during strenuous effort. Demand for L-carnitine increases in young horses up to 3 years of age and stallions in the breeding season. The addition of L-carnitine is therefore recommended especially for sports horses participating in endurance racing and horse racing.
