What are the common mineral feeds for pigs?

What are the minerals commonly used in pig feed?

Mineral feed is a feed to supplement the mineral needs of pigs. Commonly used mineral feeds mainly supplement major elements such as calcium, phosphorus, sodium and chlorine, and commonly used trace elements are generally supplemented in the form of additives. Stone powder: containing 34%_38% calcium, it is the most extensive and cheapest mineral raw material to supplement calcium. Bone meal: refers to the fine powder of animal bones after high-pressure cooking, degreasing, degumming and drying. Due to different processing methods, it is divided into boiled bone powder and steamed bone powder, and its main component is calcium phosphate. High-quality bone is pink and white, and does not agglomerate. Calcium dihydrogen phosphate: pure product is white crystalline powder, mostly monohydrate [Ca (H2PO4) H2O]. This product contains about 22% phosphorus and about 15% calcium, and its utilization rate is better than dicalcium phosphate or tricalcium phosphate, so it is often used as piglet feed. Calcium hydrogen phosphate is a white or off-white powder or granular product, which can be divided into anhydrous salt (CaHPO4) and dihydrate salt (CaHPO4 2H2O). The latter has high utilization rate of calcium and phosphorus and is widely used in production. Salt: In production practice, it is generally used to supplement salt to meet the needs of pigs for sodium and chlorine. Generally, 0.25%_0.5% salt should be used in the air-dried diet of pigs. Sodium bicarbonate: also known as baking soda, the molecular formula is NaHCO3, which is colorless crystalline powder. Sodium bicarbonate contains more than 27% sodium and has high bioavailability. It is a high-quality sodium-derived mineral feed. Sodium bicarbonate can also adjust the electrolyte balance of diet and the pH value of gastrointestinal tract. The general dosage is 0.5%_ 1%. Sodium sulfate: also known as mirabilite, molecular formula Na2 SO4, white powder. It contains more than 32% sodium and more than 22% sulfur, and has high bioavailability. Both sodium and sulfur can be supplemented, especially when sodium is supplemented, the chlorine content will not be increased. It is one of the excellent sources of sodium and sulfur. Adding it to sow diet is beneficial to relieve constipation.

Types and functions of trace additives commonly used in pig feed?

Feed additives refer to various trace components added to compound feed, whose functions are to improve the nutritional components of feed, improve feed efficiency, promote the growth of livestock and poultry, prevent diseases, reduce the nutritional loss of feed during storage and improve the quality of livestock products. Feed additives can be divided into three categories: one is substances that provide nutrition for livestock and poultry, which are generally called nutritional additives, mainly amino acids, trace elements and vitamins; The other is substances that promote the health and growth of livestock and poultry, called pharmaceutical additives, including antibiotics, fungicides, insect repellents and various hormones and enzyme preparations that change metabolic functions; The third category is feed processing and storage agents, including antioxidants, anti-corrosion and mildew inhibitors, emulsifiers, dispersants, stabilizers, anti-caking agents, flavor enhancers, pigments and so on. The latter two categories are also called non-nutritional additives.

What kinds of feed additives are commonly used?

Growth-promoting additive, trace element additive, vitamin additive, amino acid additive, antibiotic additive, anthelmintic health feed additive, mildew-proof additive or feed preservative, Chinese herbal medicine feed additive, buffer feed additive, feed seasoning additive, coloring adsorption additive, acidulant additive, etc.
