What are the minerals commonly used in pig feed? Types and functions of commonly used trace additives? What are the common types of feed additives? These questions are frequently asked questions by pig farmers about pig feed. The following is a detailed introduction of Huinong.com.
Types and functions of feed micro-additives commonly used in raising pigs?
Feed additive refers to various trace components added to the compound feed. Its function is to improve the nutrient content of the feed, improve feed efficiency, promote the growth of livestock and prevent diseases, reduce the nutrient loss of feed during storage and improve the quality of livestock products. . Feed additives can be divided into three categories: one is a substance that provides nutrients to livestock and poultry, commonly known as 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 enzymes that alter metabolic functions; the third category is feed processing and storage agents, including antioxidants, antiseptic agents, emulsifiers, and dispersants. Stabilizers, anti-caking agents, and flavor enhancers and pigments that act as attractants. The latter two categories are also referred to as non-nutritive additives.
What are the raw materials for mineral feed commonly used in raising pigs?
Mineral feed is the feed needed to supplement pig minerals. Commonly used mineral feeds are supplemented with major elements such as calcium, phosphorus, sodium and chlorine. Commonly used trace elements are generally supplemented in the form of additives. Stone powder: containing 34% to 38% of calcium, it is the most abundant and lowest-priced mineral raw material for calcium supplementation. Bone powder: refers to the fine powder that is made by the animal bones after high pressure cooking, degreasing, degumming and drying. Divided into boiled bone powder and steamed bone powder due to different processing methods, the main component is calcium phosphate. High quality bone pink and white, no caking. Calcium dihydrogen phosphate: pure product is a white crystalline powder, mostly monohydrate salt [Ca(H2 PO4)·H2 O]. This product contains about 22% phosphorus, about 15% calcium, and the utilization rate is better than that of dicalcium phosphate or tricalcium phosphate. Calcium hydrogen phosphate: a white or off-white powder or granular product, which is divided into two types: anhydrous salt (CaHPO4) and dihydrate salt (CaHPO4·2H2O). The latter has high utilization rate of calcium and phosphorus, and is used in production. More. Salt: In the practice of production, the salt is usually supplemented to meet the needs of pigs for sodium and chlorine. Generally, the amount of salt in the porcine air-dried diet is preferably 0.25% to 0.5%. Sodium bicarbonate: also known as baking soda, the molecular formula is NaHCO3, which is a colorless crystalline powder. The sodium bicarbonate contains more than 27% sodium and has high bioavailability. It is one of the high quality sodium-derived mineral feeds. Sodium bicarbonate also regulates dietary electrolyte balance and gastrointestinal pH. The amount generally added is from 0.5% to 1%. Sodium sulfate: also known as thenardite, the molecular formula Na2SO4, is a white powder. Containing more than 32% sodium, containing more than 22% sulfur, high bioavailability, can not only supplement sodium and sulfur, especially sodium does not increase chlorine content, is one of the excellent sodium and sulfur sources. Adding to the sow diet helps to reduce constipation.
What are the types of feed additives commonly used in raising pigs?
Growth-promoting additives, trace element additives, vitamin additives, amino acid additives, antibiotic additives, deworming health feed additives, anti-mold additives or feed preservatives, Chinese herbal medicine feed additives, buffer feed additives, feed flavoring additives, coloring adsorption additives, acidulants Additives, etc.
