First of all, during the transportation of magnesium oxide, ensure that the container does not leak, and no damage will occur if it does not collapse, preventing the leakage and dispersion of magnesium oxide.Secondly, during transportation, do not let magnesium oxide be mixed with oxidants and other guarantees. After the packaging is complete, it should be shipped safely.The caustic soda of magnesium oxide products in summer needs to be strictly controlled, and it should not be too high. Between -23 degrees, in winter, the temperature of the production environment should be controlled between 24-25 degrees. There are two kinds of comprehensive tests and active content tests for magnesium oxide active test methods, no matter which test method is used. The quality of magnesium oxide needs to be judged. The accuracy of the titration rapid method in the content test is relatively accurate, and the time is relatively short. Sampling and the test need to be completed within thirty minutes.

When the high-yielding dairy cows eat more refined feed during the addition period, it is easy to increase the acidity in the rumen, inhibit the activity of rumen microorganisms, cause digestive disorders, decrease the milk fat rate and cause some diseases related to this. The following should consider adding buffers:

Early lactation. Concentrates in diets account for more than 50%. Almost all roughage is silage. The milk fat rate decreased significantly or the appetite of lactating cows decreased in summer, and the dry matter intake decreased significantly. When concentrate and coarse feed are fed separately.

There are many types of buffers, generally sodium bicarbonate (baking soda), sodium carbonate (edible soda) is also acceptable, but for high-yield cows with a daily milk output of more than 30 kg, magnesium oxide or bentonite must be added .

Addition amount of various buffers

Sodium bicarbonate accounts for 0.7% to 1.5% of the dry matter intake of the diet, or 1.4% to 3.0% of the concentrated feed.

Magnesium oxide accounts for 0.3% to 0.4% of the dry matter intake of the diet, or 0.6% to 0.8% of the concentrated feed.

Bentonite accounts for 0.6% to 0.8% of the dry matter intake of the diet, or 1.2% to 1.6% of the concentrated feed.

The mixed use of baking soda and magnesium oxide is better, and the mixture of the two accounts for about 0.8% of the dairy feed (the baking soda accounts for 70% and the magnesium oxide accounts for 30%).
