Mineral feeds include mineral feeds that provide major elements such as calcium and phosphorus, and inorganic salts that provide trace elements such as iron, copper, manganese, zinc, and selenium. First, calcium source feed The calcium content of the natural plant feed is insufficient compared to the calcium requirement of the animal. Therefore, calcium source feed must be added to the diet. Stone powder is a product of comprehensive exploitation of limestone and marble. The basic ingredient is calcium carbonate, which contains 34% to 38% calcium. It is the cheapest calcium source feed. Shell powder shells are shells of seawater and freshwater mollusks. The main component of the shell is also calcium carbonate. The amount of calcium is similar to stone powder. Fresh shells must be heated and crushed to prevent transmission of disease. The dead shell's shell organic matter has been decomposed and safer. Shells are often mixed with fine sand and mud. Shell powder containing these impurities contains low amounts of calcium. Second, phosphorus source and phosphorus, calcium source feed Providing only a few sources of mineral feed is limited to phosphoric acid, sodium phosphate and so on. Phosphoric acid is liquid and corrosive. It is inconvenient to use compound feed for production. Sodium phosphate provides both phosphorus and sodium. Most of the commonly used calcium and phosphorus feeds contain both calcium and phosphorus. The bone meal is dried and crushed by animal bones after hot pressing, degreasing and degumming. The basic composition is calcium phosphate. High quality bone meal contains 28% calcium and 13.1% phosphorus. The ratio of calcium to phosphorus is 2:1. It is a balance between calcium and phosphorus. Mineral feed. The simple method of producing bone meal is directly crushed without degreasing, degumming, and autoclaving. There are many fats and proteins in the product, which are prone to spoilage and deterioration. There are also risks of transmission of disease, and care should be taken when using it. The calcium hydrogen phosphate without crystal water contains 29.46% of calcium phosphate and 22.77% of phosphorus. The crystal water of calcium hydrogen phosphate contains 23.29% of calcium and 18.01% of phosphorus. Calcium and phosphorus in calcium hydrogen phosphate are easily absorbed by animals. Common calcium and phosphorus feed. In addition, calcium phosphate and superphosphate are calcium- and phosphorus-rich feeds, but their absorption rate is not as high as calcium hydrogen phosphate. Third, the main ingredient of salt table salt is sodium chloride, which can provide two kinds of sodium and chlorine which are relatively lack of vegetable feed. At the same time, it has a flavoring effect and can enhance animal appetite. Fourth, trace element additives According to the amount of animal essential trace elements, the use of inorganic salts or oxides of trace elements formulated as a certain percentage of trace element additives to supplement the lack of animal feed essential trace elements. At present, there are many kinds of trace element additives. When using them, it is necessary to carefully identify the quality and to pay attention to the content of trace elements in different compounds.
