The invention relates to the technical field of
livestock breeding disinfection, and particularly provides a dairy cow nipple pre-dipping liquid adopting
lactic acid as a bactericidal ingredient, the dairy cow nipple pre-dipping liquid comprises the following raw materials:
lactic acid, a
plant bactericide, a surfactant, a PH buffer agent and deionized water; the preparation method of the dairy cow nipple pre-dipping liquid adopting
lactic acid as a main bactericidal component comprises the following steps: S1, mixing and stirring deionized water, lactic acid, a surfactant and a PH buffer agent; s2, adding a
mint extract and a thyme extract, and continuously stirring; and S3, finally adjusting the pH value of the mixture
system to 3.0-4.5. According to the invention, lactic acid is adopted as a main liquid
medicine, and the lactic acid, the
plant fungicide and the surfactant are compounded to realize synergistic interaction, so that the prepared finished product has the advantages of high sterilization speed, remarkable synergistic effect, high organic
pollution resistance, environmental and
skin friendliness, stable formula and convenience in use; the use requirements of large-scale breeding in a
pasture can be met. In conclusion, the method has a good application prospect.
