Problems solved by technology

At present, most of the nipple bath liquids commonly used at home and abroad are iodine preparations. Although these products have strong bactericidal power, they have certain defects: (1) Iodine residues in dairy cows may cause excessive iodine in milk, thereby affecting milk quality and food safety
(2) Pollution of iodine preparations in the industrial production process
(3) During the use of iodine preparations, due to the special color, it is easy to contaminate work clothes and other labor protection products, and it is difficult to wash
(4) The cost is relatively high
[0004] Although there are experimental reports on the use of acidic electrolyzed water dipping to disinfect dairy cows’ udders alone, the evaporation of acidic electrolyzed water dipping is fast and the duration of action is short, which cannot achieve the same effect as povidone-iodine

Embodiment 1

[0022] Example 1: Preparation of acidic electrolyzed water

[0023] According to the mass ratio of tap water and sodium chloride 1:0.5%, mix well, stir well, and then place it in the electrolytic cell of the acidic electrolyzed water generator. The area is 108cm 2 Carry out the electrolysis reaction for 20 minutes, use HCl and NaOH to adjust the pH value to 2.5-6.5, obtain the required effective chlorine concentration of 30-100 mg / L for the experiment by distilling water dilution method, and obtain the acidic electrolyzed water in the medicated bath.

[0024] The available chlorine (ACC) in acidic electrolyzed water was determined by iodometric method (American Public Health Association, 1975).

Embodiment 2

[0025] Example 2: Effect of glycerin on main physical and chemical indicators of acidic electrolyzed water

[0026] Adopt the method of Example 1 to prepare acidic electrolyzed water with available chlorine of 60 mg / L, and add 3% and 10% glycerin by volume to the above-mentioned acidic electrolyzed water, store in a 1.5L plastic bottle, and place the plastic bottle indoors. The available chlorine and pH were measured at 0h, 0.05h (3min), 0.5h, 1h, 2h, 6h, 12h, and 24h respectively.

[0027] Such as figure 1 As shown, the available chlorine content of acidic electrolyzed water added with glycerol gradually decreased with the prolongation of storage time. After standing for 2 hours, the available chlorine of acidic electrolyzed water with 3% glycerin dropped from 59.80 mg / L to 34.27 mg / L, a loss of 43%; the available chlorine of acidic electrolyzed water with 10% glycerin dropped from 59.80 mg / L to 25.64 mg / L, a loss of 57%; the loss of acidic electrolyzed water added with dif...

Embodiment 3

[0030] Example 3: In vitro simulated sterilization experiment

[0031] 1. Test strain

[0032] Escherichia coli (Escherichiacoli), Staphylococcus aureus (Staphylococcus aureus), Streptococcus agalactiae (Streptococcus agalactiae), Streptococcus dysgalactiae (Streptococcusdysgalactiae) are the main pathogenic bacteria that cause mastitis in cows. Escherichia coli and Staphylococcus aureus were provided by the Veterinary College of Inner Mongolia Agricultural University; Streptococcus agalactiae (CVCC3940) and Streptococcus dysgalactiae (CVCC3701) strains were purchased from China Veterinary Microbiology Collection Management Center.

[0033] 2. Configuration of medicated bath agent

[0034] Acidic electrolyzed water was prepared by the method in Example 1.

[0035] Acidic electrolyzed water-1: ACC: 30mg / L, pH: 5.5-6.5, hereinafter referred to as: AEW (30).

[0036] Acidic electrolyzed water-2: ACC: 60mg / L, pH: 5.5-6.5, hereinafter referred to as: AEW (60).

[0037] AEW (60)...

Abstract

The invention discloses a dairy cow nipple medicated bath agent as well as a preparation method and application thereof, and belongs to the field of dairy cow culture. The dairy cow nipple medicated bath agent uses acid electrolytic water with the volume percentage being 90 to 97 percent and glycerol with the volume percentage being 3 to 10 percent as major ingredients; the problem of easy evaporation of the single use of the acid electrolytic water is solved. The acid electrolytic water in the medicated bath agent has the disinfection characteristics of high efficiency, no residue, safety, low cost and the like; the cow mastitis can be effectively prevented; meanwhile, the glycerol can be used for protecting the skin and preventing the nipple skin crack and frozen injury. The medicated bath agent provided by the invention can completely replace the common iodine preparation; the problems of high cost, pollution on labor protection articles, iodine standard exceeding in the milk and the like are solved.

Description

technical field [0001] The invention belongs to the field of dairy cow breeding, and in particular relates to a milk teat dipping agent and a preparation method and application thereof. Background technique [0002] Acidic Electrolyzed Water (AEW) is produced by treating the water in a special device with an electric field to change the pH value, oxidation-reduction potential (ORP value), available chlorine concentration (ACC) and other indicators of the water. Produced acidic ionized water (strongly acidic electrolyzed water or slightly acidic electrolyzed water) with special functions. The special physical and chemical properties of acidic electrolyzed water determine its special characteristics, which can be summarized as follows: (1) Acidic electrolyzed water has the effect of instant sterilization and a wide spectrum of sterilization. (2) No residue, no pollution to the environment. Acidic electrolyzed water is very different from traditional chemical disinfection and...
