![]() Water-soluble vitamins by contrast are important factors in metabolic processes. With this division, one can also make an initial breakdown of their function: Fat-soluble vitamins are primarily needed for building and maintaining tissue structures. Vitamins are divided into two general categories according to their solubility: fat-soluble vitamins and water-soluble vitamins. There are two clear aspects regarding vitamin supply and need: original vitamin content in feed and the performance of vitamin synthesis in the digestive tract. In horses, self-synthesis takes place mainly in the large intestine through microorganisms, and through the absorption of added vitamins in the small intestine. This in turn is responsible for the production of the hormone calcitriol, which facilitates the storage of calcium in the bones. An important example of this is vitamin D production through UV rays. However, horses can actually produce some vitamins, partially or even completely, via self-synthesis from so-called provitamins (precursors of the actual vitamins). Horses are generally unable to make their own vitamins. Vitamins are the smallest organic substances, and important components of most metabolic processes. Vitamins Why do horses need good hay, fresh grass and sunlight? Micronutrients are divided into three main categories: from physiological properties that warrant an increased dietary allowance.Īn optimisation of the supply of macronutrients also requires an adjustment to the supply of macronutrients to provide the horse with optimum support. ![]() through illness requiring a high level of nutrients (metabolic illnesses, sweet itch). ![]() through illness causing a high loss of nutrients (diarrhoea, excessive perspiration).regional variations in the mineral stores of micronutrients (soil, drinking water).unbalanced feeding from a lack of supply or poor keeping unsuitable for horses.Possible causes for a nutritional deficiency could be: If a micronutrient is therefore lacking over any length of time, a horse can not only fall ill, but deathly ill. There are also dependent reactions between micronutrients so that a deficiency of one nutrient can also cause a deficiency of another. In contrast to macronutrients, micronutrients fulfil very special functions in the body and are not interchangeable. Overall, the body requires much smaller amounts of micronutrients than macronutrients. The quantities that need to be absorbed depend on the horse’s needs and its body’s ability store them. ![]() These small molecules then pass through the intestinal mucosa into the bloodstream and on to the areas of the body where they are needed. After ingestion, the micronutrients are broken down into their individual molecules during the digestive processes. With few exceptions, micronutrients must be taken in with food, which is why they are also called essential micronutrients. Micronutrients don’t deliver any energy themselves – rather, they act as building blocks for growth, maintenance and development of tissue, energy metabolism and other metabolic reactions. These include vitamins, macrominerals and trace minerals. In addition to energy, a horse’s body especially needs micronutrients, important factors in enzyme reactions to ensure the utilisation of macronutrients. Micronutrients – small building blocks, great benefits Often, these nutrients get much more attention in horse feed than do micronutrients, which are at least as important.Įvery animal needs a balanced supply of both kinds of nutrients so that its body can function properly. The more well-known are macronutrients like proteins, lipids (fats) and carbohydrates (sugars) which make up the organism and provide energy. Healthy horses need two kinds of nutrients in their bodies: What are vitamins, macrominerals and trace minerals?Īlthough their name offers no indication, micronutrients bring great benefits to a horse's organism.
