PREPARATION METHOD FOR COMPOUND AMINO ACID INJECTION FOR LIVESTOCK

摘要

A preparation method for a compound amino acid injection for livestock, comprising: boiling water for injection for sterilization, and then adding an antioxidant ethylenediaminetetraacetic acid disodium salt and an antioxidant sodium bisulfite at 75-95°C under the protection of a CO 2 gas flow; adding 15 amino acids at 70-100°C under the protection of CO 2 gas, then adding tryptophan, tyrosine, and cysteine hydrochloride at 60-70°C, finally adding γ-aminobutyric acid at 20-35°C, regulating the pH value, performing decolorization, etc. The problem of poor stability of amino acid injections for livestock is solved. An amino acid injection for livestock is prepared by multi-step feeding; tryptophan, tyrosine, and cysteine hydrochloride are added at 60-70°C under the protection of CO2; thus, the stability of the tryptophan and the tyrosine is effectively improved and the tryptophan and the tyrosine are prevented from being oxidized; the prepared injection is suitable for disease treatment of livestock and body recovery after diseases.
