Filed: 2020-08-18
Abstract: A method for preparing a compound amino acid injection for livestock, comprising the steps of adding an antioxidant under the protection of nitrogen; and adding 18 kinds of amino acids at one time at 60 to 70℃ under the protection of nitrogen, then adding γ-aminobutyric acid at 20 to 35 °C under the protection of nitrogen, and performing decoloration, thus solving the problem of high preparation costs of injections for livestock. Switching to nitrogen protection reduces the production costs. Further, adding 18 kinds of amino acids at one time under the condition of 60 to 70℃ reduces the operation process and labor intensity. Further, as the content of tyrosine and tryptophan in a solution is relatively high at 60 to 70 ℃, dissolving each amino acid at 60 to 70 ℃ can effectively increase the content of each amino acid in the injection. The prepared compound amino acid injection for livestock is suitable for body repair during the treatment of diseases and the recovery period after the diseases of livestock.
