Healthy horses, happy owners: What side effect does magnesium have for horses and how can it be avoided?
What side effects does magnesium have for horses and how can they be avoided? The importance of magnesium for the body is essential. This micronutrient is responsible for numerous processes in the body. A lack of magnesium can have serious consequences, especially in the context of equestrian sports, where the importance of this element is increasingly recognized. A horse's body also depends on magnesium, and the question arises: How high is the magnesium requirement in these majestic animals? How can horses meet their needs for this essential micronutrient and what options are there to provide additional magnesium? A look at the magnesium requirement in horses: Magnesium intake has been shown to have a calming effect on horses. Horses that sweat heavily or are under increased stress may require an increased magnesium intake. Mineral feed can be an additional source of magnesium. The daily magnesium requirement for horses varies between two and ten grams, depending on weight and individual needs. A veterinarian can determine the horse's blood magnesium level. Magnesium for relaxing horses It has been proven that magnesium has a calming effect on horses in stressful situations. In stressful situations, this micronutrient can help to defuse the situation and calm the horse. Especially when training young sport horses, nervous behavior poses a great challenge. The first experiences in the field, transport in a horse trailer or participation in competitions can trigger stress, which leads to an increased release of stress hormones. Many horses react nervously in such situations and show restless behavior, which often makes a relaxed forward-downward impossible. Horses and their need for magnesium The magnesium requirement of horses Magnesium plays a central role in the body of horses. It is crucial for the activity of numerous enzymes, energy supply and muscle tension. It is also essential for nerve and muscle tissue as well as for the formation of bones and tendons. Especially in young horses, which are still growing and exposed to increased demands, an adequate supply of magnesium is essential. Magnesium also has a calming effect on the nerves; nervous horses can become significantly calmer, as the micronutrient inhibits the transmission of stimuli in the nervous system. A lack of magnesium can cause various symptoms such as tension, increased nervousness, swollen legs, listlessness, lack of cooperativeness under the saddle, as well as digestive and respiratory problems. The daily magnesium requirement for horses depends on the initial weight and the owner's requirements. Sport horses that sweat heavily have a higher requirement than conspecifics of the same weight that are only lightly trained. Therefore, the daily requirement varies between two and ten grams, depending on breed, weight, daily feed intake and athletic performance. How do horses absorb magnesium and when is additional magnesium intake necessary? Horses that have sufficient access to roughage can usually meet their daily magnesium requirements through their normal feed intake. However, many horses today graze on over-fertilized pastures, where fewer grazing plants grow than in the past. Even when feeding evening hay in the stable, which comes from similar pastures, a deficiency of this micronutrient can occur. In such cases, magnesium supplementation can be useful. During the tournament season in spring and summer, when horses sweat more, additional magnesium intake is advisable, as the mineral is excreted more through sweat. An increased magnesium requirement can also occur in stressful situations such as stable or herd changes, long or unusual transports, diarrheal diseases or at the beginning of the tournament season. This also applies to pregnant and lactating mares. Young horses competing in their first tournament seasons have a particularly high demand. The new situation on the tournament grounds with many impressions, the transport and the many unfamiliar horses and people can strongly appeal to the horse's flight instinct, which leads to an increased adrenaline level and increased fat burning. The fatty acids in the tissue are linked to magnesium, which is increasingly excreted by the increased burning. Flaxseed, wheat bran and brewer's yeast as well as classic mineral feed with a high magnesium content are suitable for additional feeding. Possible side effects of magnesium in horses When using magnesium for horses, it is important to be aware that excessive intake of magnesium can also have side effects. Here are some possible side effects that can occur with too high magnesium intake: Side effect Description Diarrhea An excessive amount of magnesium can lead to diarrhea. This can lead to dehydration and electrolyte imbalance, which can be dangerous for the horse. Reduced nutrient absorption An excess of magnesium can impair the absorption of other important nutrients in the horse's digestive system. This can lead to deficiencies and impaired health. Disorders of calcium metabolism An imbalance between magnesium and calcium can lead to disorders in calcium metabolism. This can negatively affect bone health and muscle tissue. Symptoms of magnesium excess in horses A magnesium excess in horses can manifest itself through various symptoms. It is important to recognize these signs in order to take timely action. Here are some symptoms you should look out for: Lethargy and fatigue Muscle weakness or coordination problems Reduced feed intake Changes in feces, such as diarrhea Unusual behavior or aggression Tips for avoiding side effects To ensure your horse benefits from the advantages of magnesium, it is important to avoid side effects.
