Magnesium additive in feed for pigs

Magnesium in the diet of pigs, usually contains a sufficient amount. However, some species and sex and age groups (young, pregnant, high) may lack magnesium.

Most often this occurs in extreme conditions: the transition period of detention, diets changing, stress, cold, rainy summer, weaning, etc.

Magnesium digestibility of pigs from separate feed and compounds is

corn — 55.7% ,
oats — 82.7%,
barley — 54.5%,
soy flour — 60.3%
carbonate — 64.9%,
and phosphate — 54%.

Application of magnesium in the diet of pigs

Additive in piglets diets of age 2 to 4 months of magnesium in an amount of 4–5 g provides an increasing in average daily live weight gain of 6–7%, while reducing feed costs by 7% compared to animals treated with 3–3.5 g of magnesium.
Feeding to pigs of increased doses of magnesium (57 g) contributes to lower daily gain, respectively 3–4 and 7–8% compared with control (with no magnesium), and 10–11 and 14–15% compared with animals treated with 5.4 g of magnesium.
Inclusion in the composition of the diet of piglets of age 2 to 4 months magnesium in an amount of 4–5 g has a positive effect on the physiological state of the organism. There is an increasing of blood morphological indicators (leucocytes, erythrocytes, hemoglobin, total protein, glucose).
Feeding piglets from of age 2 to 4 months of 4–5 g of magnesium as part of diets allows you to get more revenue.

Large specialized farms and recommended for use in the diets of young pigs of age 2 to 4 months magnesium fertilizer AgroMag® at a dose of 4 g or 1.44 g of pure magnesium per head.
