Nowadays, most of the world's pig farms adopt corn-soybean-type diets, corn-soybean-type diets and pigs' amino acid requirements. Lysine and methionine are the first and second limits for pigs. Sexual amino acids, so often add extra.
Netizens suggested that the essential amino acids of pigs include lysine, methionine, tryptophan, phenylalanine, leucine, isoleucine, valine, and threonine. Soybean meal is rich in lysine and tryptophan, while corn contains more methionine, so corn and soybean meal are matched, amino acids are complementary, and a good nutritional balance is achieved.
Because of the lack of essential amino acids, the synthesis of proteins in the body is reduced, which causes a series of protein metabolism and related enzyme synthesis problems in the body. The most important manifestations are growth retardation and even metabolic diseases.
Lysine is mainly used for protein deposition and is rarely involved in metabolic regulation processes. The role of methionine is complicated. In addition to depositing proteins, it is also closely related to the metabolism of sulfur compounds in living organisms. In addition, it can also be used to detoxify toxic substances or drugs by methylation.
Rubber Plastic Insulation Casing Pipe
The rubber plastic material is made of high-quality rubber and polyvinyl chloride (NBR / PVC) as the main materials through mixing, internal mixing, continuous extrusion, heating foaming, cooling and cutting.
Rubber insulation material is an elastic closed cell foaming material, which has the advantages of low thermal conductivity, fire and flame resistance, humidity resistance, vibration and noise reduction, environmental protection and health, long service life, elegant appearance and convenient installation. It is widely used in central air conditioning, construction, chemical industry, medicine, textile, metallurgy, shipping, automobile, electrical appliances and other related cold and hot medium pipes or containers, can achieve the effect of reducing cold loss and heat loss. In addition, the construction is simple, the appearance is neat and beautiful, and the product does not contain fiber dust, will not breed mold and other harmful substances, so it is a new generation of high-quality thermal insulation material.
