Animal Feed grade nutrition Magnesium Oxide

Daily in the food of the cows to add the 50 g to 90 g of Magnesium Oxide, or add 0.5%, according to the essence of capacity is not only can make up for the lack of magnesium in the diet, prevent magnesium deficiency, or a good rumen buffer, can regulate rumen fermentation, and increase breast milk synthetic precursor substance absorption, increase the rate of milk and cream. 
According to related reports, adding 0.5% magnesium oxide to concentrate supplement increased milk yield by 1.6 kg and milk fat percentage by 0.145 percentage points on average, and also improved feed intake. 
Adding magnesium oxide in dairy cows' diet can prevent heat stress. Magnesium ions, potassium ions and sodium ions work together to maintain the balance of osmotic pressure inside and outside the cell and relieve the response of dairy cows to heat stress. In addition, chickens can improve the feed intake of dairy cows in summer and ensure that milk yield does not decrease. 

In addition, under the condition of heat stress, it is suggested to increase the supplemental level of magnesium oxide in the diet to compensate for the loss of magnesium in the body, so as to ensure and maintain the normal milk yield. Since both beef cattle and dairy cattle have a good equilibrium mechanism for handling excess magnesium ions, an appropriate increase in the amount of magnesium oxide will not cause adverse effects on cattle. 
The specific manifestations of magnesium deficiency in dairy cows are as follows: First of all, dairy cows will lose their appetite, slow and lethargy, and with the aggravation of the disease, dairy cows will become stiff and wobble in gait; Then, the cow will become nervous and irritable, and the muscles will shake obviously. If there is no improvement, the cow will be completely paralyzed and spasm, and if not treated in time, even death. Second, magnesium deficiency can reduce nutrient digestibility and lead to a decrease in milk production. 
When grazing ruminants such as cattle and sheep, it is important to ensure that their food contains sufficient magnesium to avoid convulsions caused by magnesium deficiency. These convulsions in ruminants are usually caused by eating magnesium-deficient forage in cold weather. There are two most common ways to increase magnesium in livestock feed: one is to mix magnesium oxide with syrup and add it to the feed; One is to add magnesium oxide directly to the feed.
