Adding 50-90 g of magnesium oxide per day to the cow's grain or adding 0.5% of the concentrate can not only supplement the deficiency of magnesium in the diet to prevent the occurrence of magnesium deficiency, but also is an excellent rumen buffer. Rumen fermentation, and can increase the absorption of milk synthesis precursors in the breast, increase milk production and milk fat percentage. According to foreign reports, the addition of 0.5% magnesium oxide to dairy concentrate supplements can increase the milk yield by 1.6 kg, increase the milk fat percentage by 0.145 percentage points, and help to increase feed intake. Adding magnesium oxide to dairy cow diet can prevent heat stress. Magnesium ions can work together with sodium and potassium ions to maintain the balance of intracellular and extracellular osmotic pressure, and alleviate the response of dairy cows to heat stress, thus improving the intake of dairy cows in summer. Quantity, to maintain milk production does not decline. It is also recommended that in the case of heat stress, the amount of magnesium oxide in the diet should be increased to compensate for the loss of magnesium in the body to ensure and maintain normal milk production. Both cows and beef cattle have a good balance mechanism to handle excess magnesium ions, so an appropriate increase in the amount of magnesium oxide does not adversely affect cattle.
When ruminants such as cattle and sheep are grazing, make sure that they contain enough magnesium in their food to prevent them from twitching due to lack of magnesium. Usually this kind of convulsion is caused by the lack of magnesium forage in cattle or sheep in cold weather. There are two common methods for adding magnesium to livestock feed: one is to mix the magnesium powder with the syrup and then added to the feed; the other is to add the light burned magnesium powder directly to the purchased feed. Magnesium deficiency is more common in beef cattle and sheep than in dairy cows because of the greater amount of concentrate in dairy cow diets and the relatively smaller concentrates in beef and sheep diets.
The amount of magnesium oxide added to the ruminant diet is 0.5% to 1.0%.
Newborn chicks can only survive for a few days while feeding a diet that is completely deficient in magnesium. When fed a low-magnesium diet, the chicks grow slowly, become drowsiness, wheezing, and have shortness of breath. After being frightened, they will show short periods of paralysis and eventually lead to temporary coma or death. According to the test, the growth rate of broilers was reduced by 80% compared with the diet containing 200 ppm of magnesium and the diet containing 600 ppm of magnesium.
For laying hens, the amount of egg production will decrease rapidly when magnesium is deficient. Low blood magnesium causes a large amount of bone magnesium to be used, the egg becomes smaller, the eggshell becomes lighter, and the magnesium concentration in the egg yolk and eggshell decreases. Studies have shown that the thicker the eggshell, the higher the concentration of magnesium in the eggshell, which suggests that properly increasing the concentration of magnesium in the diet can improve the quality of the eggshell and increase egg weight.
Usually in production, depending on the age, variety and poultry, the commonly used poultry feed magnesium concentration is between 0.15% and 0.22%.
Due to the continuous improvement of pig breeds and the continuous improvement of productivity, the nutritional needs of magnesium should be correspondingly improved. The lack of magnesium in the diet can cause a significant increase in piglet mortality. The lack of magnesium can cause a pig's footsteps, which is manifested by the fact that when the pig is standing, the rear hooves seem to be in the same place. For sows, magnesium oxide is widely used as a laxative to prevent stress syndrome such as excessive sensitivity and tail biting in captive pigs. ?
Recent studies have also shown that adding magnesium oxide to pig diets or appropriately increasing the concentration of magnesium in the diet can improve pork quality. Growing and finishing pigs fed a diet supplemented with magnesium oxide can improve growth rate and pork quality, including pork pH, color, and PSE pork. ?
According to the growth stage, body weight and production purpose, the concentration of magnesium in pig feed commonly used in the feed industry is 0.13% to 0.27%.
Freshwater fish are insufficiently dissolved in water, so it is necessary to properly supplement magnesium in the feed.
Rumen buffering regulators in additives such as sodium bicarbonate, magnesium oxide, etc.
