Scope

Scope: This document specifies the basic requirements for mechanical milking and disinfection technology in large-scale dairy farms in Ningxia, including disinfection, milking operations, equipment cleaning, and maintenance of milking machines. This document applies to the technical requirements for mechanical milking and disinfection in large-scale dairy farms in Ningxia. Main technical content: 3. Terminology and definitions: The following terms and definitions apply to this document. 3.1 Raw milk: Unaltered whole milk expressed from the mammary glands of healthy cows that meet relevant national requirements. Colostrum produced within 7 days after calving, milk during antibiotic treatment, and spoiled milk shall not be used as raw milk. 3.2 Disinfection: A measure using relatively mild physical and chemical factors to kill pathogenic bacteria on the surface or inside objects that are harmful to humans or animals, while causing minimal harm to the disinfected objects. Disinfection includes milking hall disinfection, equipment cleaning and disinfection, cleaning and wiping of cow udders, and teat dipping disinfection before and after milking. 3.3 Teat dipping: The process of disinfecting cow udders before and after mechanical milking in large-scale dairy farms. 3.4 Disinfectant: A drug used to rapidly kill pathogenic microorganisms, such as organic iodine mixtures (iodine), acid-base cleaning agents mainly composed of phosphoric acid and sodium hydroxide, Chlorhexidine, and alcohol. 3.5 Mechanical milking: A process that uses vacuum to suck milk from cow udders, imitating the physiological action of calf suckling. A vacuum pump generates negative pressure, a vacuum regulating valve controls the vacuum level of the milking system, and a pulsator generates milking and resting rhythms. Air enters the milk claw through small holes to help transport milk from the milk claw to the milk pipeline. 3.6 Milk claw: A container for collecting milk from four milk cups. Before
