Magnesium additive in feed for cattle
Magnesium is a «building» material for bones and teeth, it is a significant part of various enzymes and plays an important part in metabolism. Along with calcium, magnesium ensures normal functioning of the nervous and muscular systems.
Magnesium assimilation by cattle
Bioavailability of different sources of magnesium (MgO and Mg(OH)2) is similar when fed them by full diets or by mineral fertilizing. Magnesium absorption in the digestive tract of animals is difficult due to the formation of sparingly soluble compounds of magnesium in the gut. Only magnesium ions and soluble magnesium salts of bile acids are absorbed. Assimilated magnesium stored in the liver, and then much of it goes into the muscles and bones.
Undigested magnesium excreted in the feces and urine. In muscles, magnesium is involved in activation of anaerobic metabolism. In muscles contains more magnesium than calcium.
Digestibility of magnesium (Mg) in cattle feed from juicy
high-proteinfeed is about 10%, of grain and mineral supplements — 30–35%
- high content of fats, salts, P, Ca;
- availability of phytin, fiber.
- The optimum ratio of calcium, magnesium and phosphorus: Ñà: Mg = 1: 0,5; Ñà: Ð = 1: 1,5
To meet the needs of magnesium of
high-producingcows the daily intake of magnesium in the feed must be 25–60 grams, depending on the availability of the magnesium in the feed.
Digestibility of magnesium in dairy cows in the
winter-stallperiod is an average of about 30%. In leguminous this element is in the form of more digestible than cereals. For high- producing cows in the transition period ( May-June) 50–60 g of magnesium per day should be added to the diet with an adequate level of magnesium in the diet (2.1–2.3 g / kg), and in the period from June to September — 25–30 g. Thus, the fat content of milk increased by 0.1–0.15%.

If estimation of the diet is based on tabulated data density of the feed, it is recommended to increase the rates on guaranteed bonus of 6 g Ca, 4 g P, 5 g of Na and Mg 2 g per head per day.
The magnesium content of silage depends on the type of soil on which grass was growing, and of the quality of its fertilizer. In addition, excessive fertilization of soil by potassium and sodium reduces the magnesium content in growing plants. Young grass is most rich in potassium and raw protein, but provided little by useful raw fiber and carbohydrates. If a cow is not suitably prepared for pasture feeding, then its rumen microbiology will convert the formed ammonia in protein of microorganisms. Ammonia and potassium inhibit reabsorption of magnesium through the mucosa of the rumen, and therefore the content of magnesium in the blood reduces. In the young grass and other types on grass absorption rate of magnesium decreases from normal (20–30%) to 10–15%.
Effective method is spraying of rangeland by suspension of magnesium hydroxide («AgroMag® AktiMaks») before grazing. It can increase the rate of magnesium absorbed with grass and significantly reduces the risk of grass tetany.
