Mineral feed or mineralized concentrated feed

Sense or nonsense? 

Horses that are not supplied with sufficient minerals can develop a mineral deficiency in the long term. This is because an adequate supply of essential micronutrients, especially trace elements, is no longer available from hay and grass. Feeding mineralized concentrates, often in the form of muesli or pellets, is therefore still very popular. It is an uncomplicated way to provide horses with energy, minerals and vitamins at the same time.

Why does AGROBS not mineralize its concentrated feed and instead offers concentrated feed and mineral feed separately?

Does fully mineralized concentrated feed meet your horse's individual requirements?

Every horse has individual energy and nutritional requirements. Concentrated feed is used to cover the increased energy requirements of sport horses or broodmares, for example. It should only be supplemented if horses are unable to maintain their weight on hay alone. A 600 kg warmblood requires around 63 megajoules (MJ) of metabolizable energy (ME) to maintain its weight without additional training. The horse should cover this energy requirement purely through roughage such as hay - additional concentrated feed is not necessary.

Further explanation:

11 kg of hay with an average energy content of 6 MJ ME per kilogram provides around 66 MJ ME per day. To supplement the missing micronutrients, a mineralized concentrated feed with an average energy content of 10 MJ ME per kilogram is added. According to the manufacturer's recommendation, 2.5 kg of concentrated feed per day must be fed to cover all requirements, resulting in an additional energy and calorie intake of 25 MJ ME per day. In our example, this means that covering the mineral requirement with a mineralized concentrated feed results in excess energy, which makes the horse fat in the long term.

Does the need for vitamins and minerals really always increase or decrease in line with the need for energy?

Horses that work every day, on the other hand, have an increased need of energy and may therefore need a concentrated feed. However, the need for energy is very individual: A leisure horse that is ridden cross-country at a walk for an hour every day only burns approx. 6 MJ ME in addition to its maintenance requirement. For a sport horse it can be 25 MJ ME or even more. While a leisure horse only needs 500 g of concentrated feed in addition to hay, for example, to cover its energy requirements, a sport horse with a performance requirement of 25 MJ ME needs 2 kg of the same concentrated feed.
However, the need for minerals and vitamins does not increase linearly with the need for energy and varies greatly depending on the nutrient. A sport horse may therefore need five times the amount of energy to cover its performance requirements, but not five times the amount of zinc, selenium, iodine or vitamin A. It therefore makes sense to consider the feeding of energy (through a concentrated feed) and micronutrients (through a mineral feed) separately from each other in order to provide each horse with an individual supply that meets its needs.
