MDCP - (the mixture of MCP and DCP ) to complement the need of young livestock with P ,CA and minerals nutrition to accelerate its growth and development, shorten the fattening period, accelerated weight gain, increase the rate of breeding and survival, enhance the disease resistant ability to cold, and osteomalacia, pullorum disease prevention.MDCP, also known as calcium phosphateIII, chemical formula is CaHPO4 2H2O + Ca (H2PO4) 2 H2O, molecular weight of the body is 252.07, after dryed the product is white powdery crystals or granules. Neutral, soluble in dilute acid, and 40% was dissolved in water, heated to about 90 °C began tolose crystal water .? High purity, the ratio of P and CA is appropriate to ensure that its high biological potency.? This product uses a unique high-tech, to the variety of raw materials,the harmful impurities can be control within an effective scope. ? This product drying process in advanced,under the premise containing low free water,ensuring the product not to lose the crystal water, avoiding the reduction of the biological potency in the drying process ..
