饲料中氨基酸快速分析

Lysine is an essential amino acid which means that it cannot be synthesized in the body at a sufficient rate to meet the physiological needs of the body, and therefore must be supplied by the diet. Lysine is one of the most important essential amino acids: it is a building block of protein and an important component in amino acid balance. It is a limiting amino acid in cereal grains and in some vegetable protein sources, therefore requiring synthetic supplementing to meet the animals needs. Lysine is a structural element of proteins; it is a vital component of the enzymes and is present in almost all the tissues of the animal. Because lysine is involved in a large number of metabolic processes it has a fundamental role in animal nutrition and animal health. Improvement in animal performance through better amino acid balance, better carcass quality, and prevention of lysine deficiency are some of the benefits associated with the right lysine content in the animal diet. For example, for piglets and pigs the use of synthetic lysine allows an increase in feed consumption and body weight gain; and an improvement in feed conversion and in nitrogen retention. Particularly with pigs, its use allows an improvement of the carcass quality. Using the Biochrom 30 buffer system, lysine can be accurately quantified in less than 10 minutes to enable adjustments to the formulation of feedstuff.
