Hebei Messi Biology Co., Ltd.stated that as a feed additive: magnesium oxide is mainly used in dairy cow feed, and secondly in pig and chicken feed. Magnesium is the main cation in the cell as a coenzyme factor for enzymatic reactions, and participates in the main metabolic pathways in the body. Extracellular magnesium is essential for the normal nerve conduction, muscle contraction and bone mineral element deposition of the animal body.
Function for dairy cows: magnesium oxide is the most widely used inorganic magnesium source in ruminant feed. It is an alkalizer. It increases the pH value of the rumen, which can increase the mammary gland’s uptake of blood metabolites and increase the milk fat rate. Studies have shown that the addition of baking soda and magnesium oxide in the diet in proportion can effectively adjust the pH value of the rumen fluid, so that dairy cows have a better rumen environment, obtain the best production performance and feed conversion efficiency, and thus increase milk production.
Function for chickens: Newborn chicks can only survive for a few days when fed a diet that is completely deficient in magnesium. When fed a low-magnesium diet, chicks grow slowly, become lethargic, pant, and breathe rapidly. When frightened, they will experience short-term convulsions, which will eventually lead to temporary coma or death. For laying hens, egg production will drop rapidly when magnesium is deficient. Low blood magnesium causes a large amount of magnesium utilization in bones, smaller eggs, lighter eggshells, and a decrease in magnesium concentration in yolk and eggshell. Studies have shown that the thicker the eggshell, the higher the magnesium concentration in the eggshell. Therefore, appropriately increasing the magnesium concentration in the laying hen diet can improve eggshell quality and increase egg weight.
Function for pigs: Due to the continuous improvement of pig breeds and the continuous improvement of productivity, the nutritional needs of magnesium should be increased accordingly. Feeding growing and finishing pigs with a diet supplemented with magnesium oxide can improve growth rate and pork quality, including the pH value and color of pork, and reduce PSE pork.
Function for freshwater fish: Freshwater fish need to be appropriately supplemented with magnesium in the feed because the amount of dissolved magnesium in water is insufficient.
