Abstract

The invention discloses a composite functional amino acid feed additive and an application. The composite functional amino acid feed additive is prepared from the raw materials of L-glutamic acid, L-glutamine, glycine, L-arginine and L-cysteine at a certain weight ratio; the preparation method comprises the following steps: step A, respectively weighing the L-glutamic acid, the L-glutamine, the glycine, the L-arginine and the L-cysteine; step B, sequentially feeding the weighed amino acids into a mixer and then uniformly mixing to obtain a composite amino acid feed additive. The invention also discloses the application of the composite amino acid feed additive to livestock and aquatic livestock feeds. The composite functional amino acid feed additive is reasonable in formula, convenient to use, high in safety, free of resistance to drugs and capable of improving animal intestinal health, promoting growth, improving feed conversion efficiency and reducing incidence of diseases, so the composite functional amino acid feed additive can be used for effectively replacing an antibacterial growth promoting agent.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry or feed, more specifically relates to a compound functional amino acid feed additive, and also relates to the use of a compound functional amino acid feed additive. Background technique [0002] In recent years, more and more studies have shown that the cell- and tissue-specific functions of amino acids are not only reflected in protein synthesis, but also play an important role in many signaling pathways. These amino acids that can participate in and regulate important metabolic pathways to improve animal or human health and survival, growth and development, lactation and reproductive performance are collectively referred to as functional amino acids, including arginine, glutamine, branched-chain Amino acids, tryptophan, glycine and proline, etc. [0003] Glycine not only participates in the composition of body proteins, but also is the basic structure of many important substances such ...
