Novel dairy cow nipple protection film and preparation method thereof

Abstract

The invention relates to a novel dairy cow nipple protective film. The protective film is prepared from a film-forming fiber and a plurality of skin moisturizing agents and disinfectants. A protective film can be formed, and the disinfection effect is achieved; and the film has no irritation, no side effect and good air permeability. After the dairy cow squeezes the milk, the product can form a layer of protective film on nipples within 3-5 minutes to prevent bacteria from invading, and also can disinfect, so that the mastitis is effectively prevented.

Description

Technical Field

[0001] The invention discloses a novel protective film for the nipple of a dairy cow, which is made of a film-forming fiber, a plurality of emollients and disinfectants. The product can form a protective film after the dairy cow is milked, and can effectively prevent mastitis, and belongs to the field of veterinary health products. Background Art

[0002] Mastitis is one of the three major diseases of dairy cows, with a high incidence rate and great harm, and is one of the important reasons for the economic loss of dairy cow production. Therefore, the ranch must disinfect the nipples of dairy cows with a medicated bath every time after milking.

[0003] Traditional medicated bath liquids have gone through the development of ordinary iodine tincture, hydrogen peroxide and various medicated bath liquids, but these medicated bath products are only simple instant sterilization and disinfection. The highest incidence of cow mastitis is within the 15 minutes after milking and before the nipples close. Therefore, the instant sterilization of traditional medicated bath liquids cannot completely prevent cow mastitis, resulting in a high incidence of cow mastitis. Summary of the invention

[0004] The present invention develops a new type of dairy cow nipple protective film. The dairy cow uses the product after milking, and a protective film can be formed on the nipple within 3-5 minutes to prevent bacteria from invading and also can disinfect, thereby effectively preventing mastitis.

[0005] Liquid protective film is a cow nipple protection product made of multiple effective ingredients such as film formers, disinfectants, emollients, emulsifiers, stabilizers, enhancers, surfactants, etc.

[0006] A novel dairy cow nipple protective film, characterized in that it is composed of the following components by weight percentage:

[0007] Polyvinyl alcohol (PVA) 1799 was selected as the film-forming agent.

[0008] The disinfectant used was powdered povidone-iodine (PVP-I).

[0009] Medical grade glycerin (propylene glycol) is used as a moisturizer.

[0010] The emulsifier used was OP-10 (polyoxyethylene dodecylphenol ether).

[0011] The stabilizer is a mixed solution of sodium iodide and sodium iodate, which is used to increase the iodine content and the stability of iodine.

[0012] The synergists are ethanol and glacial acetic acid.

[0013] Sodium dodecyl sulfate was selected as the surfactant.

[0014] Ingredient Description: (1) Mixing of povidone iodine solution: Add sodium dodecyl sulfate as a surfactant to water, then add glacial acetic acid as a synergist, and then add povidone iodine powder and stir to mix; (2) Preparation of sodium iodide - sodium iodate solution: Prepare a mixed solution of sodium iodide and sodium iodate; (3) Preparation of PVA solution: Dissolve flocculent PVA (1799) under high temperature and high pressure, and then filter. (4) Final mixing: Add a skin moisturizer (glycerol), emulsifier OP - 10, synergist (medical alcohol), and sodium iodide - sodium iodate solution to the povidone iodine solution. While it is hot, add the PVA solution and stir well. Description of the Drawings

[0017] Example 1 A new type of dairy cow teat protection film, calculated by 100 parts, is composed of the following raw materials in parts by weight:

[0018] A preparation method of a new type of dairy cow teat protection film: 1. Preparation of PVA solution: Weigh 2.5 kg of PVA (1799), add 16 kg of water, dissolve it under high pressure at 122 °C for 30 minutes. After taking out the pressure cooker, add 17.3 kg of water while it is hot, stir well and then filter. Prepare two portions of the same solution and mix them to obtain 66.6 kg of PVA solution; 2. Preparation of PVP - I solution: Weigh 15 kg of water, add 0.34 kg of glacial acetic acid, then add 66.7 g of sodium dodecyl sulfate and dissolve it. Finally, add 667 g of povidone iodine and dissolve it to obtain 16.1 kg of PVP - I solution; 3. Preparation of sodium iodide - sodium iodate solution: Weigh 5 kg of water, add 120 g of sodium iodide, add 33.4 g of sodium iodate and dissolve it to obtain 5.15 kg of sodium iodide - sodium iodate solution; 4. Final preparation and sample addition sequence: PVP - I solution (16.1 kg) → glycerol (3 kg) → emulsifier OP - 10 (2 kg) → ethanol (4 kg) → sodium iodide - sodium iodate solution (5.15 kg) → 6% PVA solution (66.6 kg) → Add water (3.15 kg), stirring each time you add sample.

[0019] Example 2 A novel dairy cow nipple protective film is composed of the following raw materials in parts by weight per 100 parts:

[0020] A preparation method of a novel dairy cow nipple protective film: 1. Preparation of PVA solution: weigh 2.8 kg of PVA (1799), add 16.5 kg of water, dissolve under high pressure at 122°C for 30 minutes, take out the pressure cooker and add 17.3 kg of water while hot, stir well and then filter, prepare two identical solutions and mix them to obtain 67.6 kg of PVA solution; 2. Preparation of PVP-I solution: weigh 15 kg of water, add 0.2 kg of glacial acetic acid, then add 80 g of sodium dodecyl sulfate and dissolve, finally add 800 g of povidone iodine and dissolve to obtain 16.3 kg of PVP-I solution; 3. Preparation of sodium iodide-sodium iodate solution: weigh 5 kg of water, add 180 g of sodium iodide, add 49.5 g of sodium iodate, dissolve, and you can get 5.23 kg of sodium iodide-sodium iodate solution; 4. Final preparation and sample addition order: PVP-I solution (16.3 kg) → glycerol (5 kg) → emulsifier OP-10 (1.5 kg) → ethanol (3 kg) → sodium iodide-sodium iodate solution (5.23 kg) → 6% PVA solution (67.6 kg) → Add water (1.37 kg), stirring each time you add sample.
