Magnesium is an important element in the activation of over 300 enzymes. Without magnesium, protein synthesis in the metabolism is disturbed, lipolysis does not function optimally, and blood glucose is not broken down to a sufficient degree (Matthei, 1996). The influence of magnesium on the metabolism of the musculature and nervous system is considerable. magnesium is considered to be an "anti-stress" mineral, since sufficient supplies reduce the release of stress hormones.
Magnesium in horses
Magnesium absorption takes place in the small intestine, whereby only 10-60% of the magnesium in feed is absorbed and 70% from mineral substances containing magnesium. A horse weighing 500 kg stores about 125 mg of magnesium, 75 g of this amount in the skeleton, 45 g in the heart, muscles and liver. The normal plasma / serum level in horses is 18-24 mg Mg/l or 0.75 - 1.0 mmol Mg/l (Meyer, 1996).
The recommended dietary magnesium supply for horses is 20 mg Mg/kg of body weight per day, corresponding to a maintenance requirement of 10 g Mg/500 kg body weight.
The following deviations in requirement levels should be kept in mind:
Work light, moderate, heavy: 10.5 g / 11 g / 13 g / animal / day
Pregnancy 9th-11th month: 10.5 g / animal / day
Lactation, 3rd month: 13 g / animal / day
Foals 3rd-6th / 7th-12th month: 5 g / 6 g / animal / day
Foals 13th-18th / 19th-24th month: 7.5 g / 8.5 g / animal / day
Foals 25th-36th month: 9 g / animal / day (modified, Meyer, 1996)
Magnesium supply in grazing mares and foals is usually sufficient at average grass contents levels of c. 2 g Mg/kg DS (Finkler-Schade et al., 1996).
Not meeting increased requirements during pregnancy and lactation, in cases of extreme and unbalanced nutrition during training, competition sports, transport and stall changes, and in stressful situations in general.
Increased elimination in gastrointestinal and urogenital tract illnesses.
Corresponding to the important role played by magnesium in the metabolic system in general and in muscle and nerve tissue metabolism in particular, the following
How to tell if a horse requires supplementation:
Loss of appetite, exhaustion, poor condition, excessive excitability, nervousness, sweating, muscular tremor, muscle strains, cramps.
Vitamin B12 (Cobalamines) in horses
Cobalamines in the vitamin B12 group have a central cobalt atom. For this reason, an insufficient supply of vitamin B12 is a possibility in regions with extreme cobalt dearth.
The cobalt requirement in horses is 0.05-0.1 mg/kg feed DS. Like magnesium, vitamin B 12 also contributes to the control of the sensitivity of the nervous system to stimulation.
Equistro Betamag 12
High levels of physical stress can quickly lead to a horse showing nervous reactions. The combination of a magnesium salt with immediate availability and a magnesium salt with delayed availability in EQUISTRO BETAMAG 12, together with vitamin B12, can assist with restoring willingness to perform.
EQUISTRO BETAMAG 12 can be administered in long periods of high stress levels and to highly nervous animals for longer periods. To compensate insufficient supply or prepare an animal for physical and nervous stress (loading, transport), the daily supplement can be doubled for c. 10 days.
