With the continuous improvement of people's living standards, everyone pays more attention to health and health, among which dairy products are more popular products, among which fresh milk is even worse. There are now more farmers raising cows, and the most important thing is to raise cows. If the milking operation is improper or improperly stored, it will not only make the high quality raw milk worse, but also harmful and unprofitable for the cow. Therefore, in order to squeeze out the high quality milk, we must master the following steps and precautions. .
First, the steps of milking cows
1. Clean the nipples. The purpose of cleaning the nipple: one is to stimulate the nipple, and the other is to squeeze out the clean milk.
There are three processes for cleaning the nipple: rinsing, drying, and massage. When washing, please pay attention to the area of ​​washing is not too large, because the area is too large, the dirt in the upper part of the breast will flow down with the water, concentrated to the nipple, increasing the chance of infection of the nipple. Wipe dry with a clean towel or paper towel, pay attention to a cow or a piece of paper. The towel is cleaned and disinfected after use. Then massage the breasts. Promote the release of milk. This process should be gentle and fast, and it is recommended to complete it within 15 to 25 seconds.
2. Discard the first 1 to 2 milk. This allows the milkman to detect abnormal milk and clinical mastitis early, discard the milk containing high bacteria count, and provide a strong milk stimulation. It should be reminded that: squeezing the head 1 to 2 milk, usually before cleaning the nipple, can also be done after cleaning the nipple. It is recommended that it be done before the nipple is cleaned to give the cow a strong milk stimulation early. Waste milk is packed in special containers to reduce environmental pollution.
3, nipple medicine bath. Soak the nipple with a disinfectant solution before milking. Then stay for 30 seconds and dry with a paper towel or towel.
It is necessary to implement this procedure in a dairy farm with poor sanitation or mastitis due to environmental problems. Studies at Cornell University in the United States have shown that immersing the nipples with milk before milking has the same effect as reducing the bacteria on the surface of the nipples and washing the nipples with water. The recommended procedure for the nipple bath is as follows: remove the debris from the nipple by hand; discard the first 1-2 milk of each nipple; take a medicated bath for each nipple and wait for 30 seconds to dry.
4. When milking the milking machine, you should pay attention to the correct use of the milking machine. Observe if the milking machine is working properly. If the machine is not working properly, it will lead to incomplete milking or damage to the breast; manual milking should minimize the milking time.
5. After the milking, the nipple of the medicated bath is squeezed for 15 minutes. The annular sphincter of the nipple can restore the contractile function, and the nipple hole should be closed to prevent the open nipple from being attacked by environmental pathogens. And take a medicated bath in time. The disinfectant is attached to the nipple to form a protective film, which can greatly reduce the incidence of mastitis.
Second, the precautions for milking cows
1. Ensure the cleanliness of the milking machine and pipeline.
2, to maintain the health of the cattle, especially the health of the breast and hindquarters.
3. The extruded milk flows into the storage tank from the pipeline and is not in contact with the air, which can reduce the amount of bacteria.
4, the milkman should wear a overalls, prepare disinfection potions and utensils, wash your hands.
5, before the milking must be prepared to wipe the towel for the breast, a piece of cattle, can not be mixed.
6. Cool the milk. Generally, cold-cold cooling is used, and the temperature of the milk is rapidly lowered from about 33 degrees Celsius to below 10 degrees Celsius.
7. Maintain a good milking environment. Do not feed dusty feed when milking.
8. Strictly implement the daily milking time and do not disturb the established law.
9. Make a good milk record. Make a record of the milk production of each cow on that day, and do a good job of milk production per day in the cow house so that managers can grasp the production dynamics.
The above are the steps and precautions for milking cows. In order to ensure the quality of milk, dairy farmers must master the above steps and precautions when milking, to avoid affecting the milk quality due to improper operation.
