At the end of each milking, the milking equipment and site shall be thoroughly cleaned and disinfected to keep clean and sanitary.

The sewage discharged from the drainage outlet shall be cleaned up in time, kept unblocked, and discharged in time to prevent overflow and leakage to low-lying places.

Millions of bacteria can be attached to a fly. The milking parlor should prevent mosquitoes and flies from entering, and weeds in the breeding ground of mosquitoes and flies should be eradicated frequently. Weeds and excrement should be transported to the excrement treatment area for centralized treatment. Burning weeds is prohibited.

milking station surrounding environment weekly application2%Sodium hydroxide solution or other high-efficiency low-toxicity disinfectant disinfection once.

The sewage tank and sewer in the station are disinfected once a month with bleaching powder to kill mosquitoes, flies and other pests and provide a good milking environment for cows.

 

Staff Hygiene

Milk parlor staff must be in good health and often trim their nails. When entering the milking station, you should wear work clothes, work shoes and work hat. To wash hands, and by ultraviolet disinfection. Work clothes, work shoes and work caps must be disinfected daily.

Cattle with high somatic cell count and unhygienic preparation before milking may cause serious contamination of milkers' hands. Studies have shown that,50%The milkman's hands are contaminated with bacteria before milking, while the milking is almost100%Contaminated. All measures should be taken to reduce the direct contact of milk with hands, and hands should be kept clean at all times, especially when moving between cows. Rinsing with water or immersing your hands in a medium disinfectant (when moving between cows) will help. However, the number of bacteria may still be high due to rough skin, cracks, etc.

A good way to reduce the spread of mastitis between cows with contaminated hands is to wear disposable plastic or rubber gloves and dip them in disinfectant when moving between cows.

 

Cleaning and disinfection of nipples and breasts before milking

The infection route of mastitis is mainly the pathogenic bacteria attached to the mouth of the nipple and enter the breast through the nipple. Through the digestive system, genital tract, skin damage, through the lymphatic system and blood circulation system into the breast tissue and infection is only a minor position.

The sanitation and disinfection of the cattle environment can only be done relatively well and poorly, and it is impossible to achieve the degree of sterility. Cows live in this environment, breasts and nipples cannot be free from contact with various pathogenic bacteria. The key is how to avoid or reduce the invasion of these pathogenic bacteria into the breast tissue.

Before cleaning the nipples and breasts, ensuring that the cow's body is clean is not only important to reduce the number of milk bacteria and improve the quality of milk, but also affects the preparation time and milking time before the milking machine is put on. In general, such as during milking more5%Dairy cows whose udders and nipples are contaminated with cow dung and other debris need to be adjusted in certain areas to improve the cleanliness of the cow body.

The basic goal of good milking hygiene is to milk on clean, dry teats, which plays an important role in reducing bacteria on the skin of the teats.

Research materials at Cornell University in the United States clearly show that manual drying of nipples is much more effective than other nipple and breast preparation techniques.

Even cows that appeared to have relatively clean teats before milking had higher levels of bacteria in their milk if they were not prepared or scrubbed with only a wet towel or scrubbed with only a dry towel than those that were properly prepared and dried3~16Times.

Studies have shown that the most ideal method of nipple and breast preparation includes cleaning the nipple with a wet paper towel soaked in disinfectant, and then drying the nipple with a disposable paper towel, which can significantly reduce the number of bacteria on the breast skin and reduce the incidence of mastitis. The surface of the breast should be kept dry (even if dirty), and it is not encouraged to wet any part of the breast without wiping it dry, because a wet surface of the breast can cause dirty bacteria-contaminated water to flow into the teat cup during milking and increase the number of bacteria in the milk.

Cleaning and drying the teats not only reduces the number of bacteria, but also the teat cups are less likely to fall off or produce noise, and reduces the incidence of new mastitis caused by the milking machine.

Wash or nipple pre-bath and dry with disposable paper towels (or a separate towel for each cow) (10s) remove approx.1/2of bacteria.

In dairy farms with a high incidence of mastitis, milkmen can be seen scrubbing the breasts of all cows with a towel, which is one of the most imperceptible ways of transmission of mastitis in cows.

As for the choice of towels, paper towels or other water-absorbent materials, it depends on the amount of water used to clean the nipples or the amount of nipple medicine bath and the cleanliness of the nipples.

 

A study by the University of Minnesota in the United States shows that when the nipple is pretreated with an effective bactericidal solution, and then the nipple is massaged by hand,30~40sAfter drying with a paper towel, the nipple is clean and the milk effect of the cow is more obvious. This procedure is called“Minnesota Pre-Milking Breast Preparation Method”.

A study by Cornell University in the United States shows that compared with not taking any cleaning measures, the correct washing of the nipples before milking can reduce the amount of milk in the milk and on the nipples.75%~85%of bacteria.

Cornell University also concluded from a herd of bacterial immunity tests that pre-milking compared to no cleaning measures“Wet towel—Dry towel”Washing method can reduce disease transmission43%,“Medicinal bath before milking—Dry towel”law can be reduced66%.

Through the medicated bath before milking, the main reason for the significant reduction in neonatal mastitis is that the disinfection of the nipple end and the nipple tube is better, but the liquid medicine penetrates into the funnel-shaped nipple tube, which can better achieve the purpose of eliminating bacteria than washing and wiping.

 

In addition, it can be seen from some farm experiments in Vermont, USA,“Medicinal bath before milking—Dry towel”The cleaning method compared“Wet towel—Dry towel”of washing methods, whose main mastitis pathogens decreased on average54%Left and right.

A large number of domestic studies have shown that nipple medicated bath is the best and least cost method of choice for controlling mastitis. Daily period of labor2times, daily during lactation3Times, after dry milk1Daily during the week.1Times.

Pay particular attention to the following3a lactation medicine bath work:

Annually7,8,9In the month, the temperature and humidity are high, the reproductive ability of pathogenic microorganisms is enhanced, and the chance of infection in dairy cows is increased;

Section1,2The milk yield reached the highest at the month of lactation, the cow's feed intake increased, the breast burden was large, and the incidence of mastitis increased;

Near the end of the lactation period, due to long-term milking, the opening of the nipple tube increases, and external pathogens are easy to invade the breast.

 

During milking, cow dung, sewage, dirt and bacteria from other parts of the milk area (especially the bottom of the udder) can easily enter the milk cup, udder and milk, resulting in an increase in the somatic cell count of cows and the occurrence of mastitis, which will be more serious in the rainy season.

 

 

Post-milking teat medicated bath

Have a nipple bath immediately after milking, because after milking15minThe posterior sphincter of the nipple can close the opening of the nipple canal.15minThe open nipple hole is vulnerable to environmental pathogens. Timely medicine bath, so that the disinfectant attached to the nipple to form a protective film, can greatly reduce the incidence of mastitis.

 

In addition to the use of pre-milking medicine bath, at present, British Sinoe post-milking medicine bath not only has strong sterilization performance, but also can form a breathable protective film outside the nipple to prevent bacteria from invading, preventing cracking, sunburn, etc. of cow nipples, and protecting nipples under extremely cold and hot weather, rainy weather, wet grass, dirty bedding and other conditions to avoid bacteria in breast ducts, thus effectively controlling the occurrence of cow mastitis.

Sinopauli can provide biological disinfection and protective barrier during the milking period. It can form a protective film and moisturizing effect on the nipple, and can prevent environmental biological invasion of the nipple orifice and skin abrasion.

 

 

Cleaning and disinfection of milking equipment

During mechanical milking, the cow's teats are open for the release of milk and bacteria can easily invade. Milking machine cleaning and disinfection is not strict will cause the spread and spread of pathogenic microorganisms, resulting in a high incidence of mastitis in dairy cows, which will bring huge economic losses to dairy farming.

If the equipment is not cleaned well, bacteria on the surface of the teat cup set and other parts of the milking machine will increase quickly, thus providing the possibility for it to enter the breast through the loose and open mouth of the milk duct and cause infection. Therefore, the cleanliness of the milk collector and the milk liner surface should be carefully checked.

Before milking, rinse the milking equipment once with clean water.

Immediately after milking, use clean warm water(38-43 ℃)Clean the milking equipment to prevent residues in the pipe from hardening due to temperature drop and difficult to rinse.

Cleaning water can only be circulated in the system once, then discharged, and repeatedly cleaned until the water is clear.

After washing with warm water, immediately usepH11.5Alkaline liquid circulation cleaning6~10min, starting temperature70~75 ℃, After circulation, the water temperature cannot be lower48℃.

Rinse with warm water after alkaline washing5min.

When two consecutive milking shifts are cleaned according to the above procedure, the lye is changed to acid for the next shift.pHshould be controlled in3~3.5, Still rinse according to the above procedure, the main purpose of pickling is to clean the residual minerals in the pipeline.

It should be carried out alternately according to the frequency of two classes of alkaline washing and one class of pickling.

 

 

 

 

When milking in a bench-top milking parlor, if a continuous milking time is too long, a short drinking water flushing procedure should be set in the middle of milking to reduce the probability of contamination and cross-infection.

Special attention should be paid to the milk lining head. The outer surface of the milk lining lip along the mouth cannot be cyclically cleaned. Therefore, it needs to be cleaned manually. At the same time, the cleaning of the inner surface of the milk lining and the uniformity of the surface is also very important. If the inner surface of the milk lining is rough and has cracks, it will become a breeding ground for pathogenic microorganisms, which will not only affect the quality of milk, but also bring about mastitis in dairy cows.“outbreak”.

Milk pumps, milk pipes, valves, etc. should be brushed again with clean water after each use, every week2Washing, cleaning.

The pulsator, milk collector and milk duct shall be removed and washed at least once a week. All parts that come into contact with milk are rinsed with warm water and then soaked in0.5%Scrub in alkaline water, and finally rinse with water, dry.
