Strengthen dairy cattle feeding management, adhere to the "prevention-oriented, comprehensive prevention and control" policy. Every spring and autumn, dairy cows should be immunized against epidemics. At the same time, large disinfection should be carried out inside and outside the dairy farm to ensure the cleanliness and hygiene of the cow body, cowshed, surrounding environment and all appliances, and to strengthen the health care of cows. Dairy cows are groomed with wooden combs every day; they are often massaged before milking; cotton and yarn bras are placed on their nipples in winter and summer respectively to avoid frostbite or mosquito bites; cows are given warm water when the temperature is below 12 C; cows are cleaned in time, and their hooves are regularly trimmed to prevent cow hoof disease.

The cows should be carefully cared for. Besides giving them good food and shelter, cattle farmers should also be kind to them. They should not swear at them casually. They should not talk loudly and run back and forth in the cowshed. They should not let dogs and other animals bark and bark at the cattle farm. Otherwise, the cow's milk production will be affected. If a veterinarian injects a cow, it will remember. Later, when veterinarians enter the cattle pen, cows will be angry or frightened. Therefore, dairy farm keepers should let veterinarians have nothing to do in the cowshed to increase affinity with cows.

At ordinary times, dairy farmers should pay attention to the health of cows.
1. Look at food intake. Healthy dairy cows have a strong appetite and fast speed of eating grass. They begin to ruminate when they are full. When the grass is fresh and mildew-free, if they find that the cows are only sniffing at the grass, they are unwilling to eat or eat less, that is the manifestation of illness.

2. Examine the condition of feces and urine. Healthy cow droppings fall into the ground in the shape of a pancake, round, high-edged concave, and emit a fresh odor of cow droppings, urine is light yellow, transparent. If it is found diarrhea symptoms that the stool is granular, and there is even stench, blood and pus, urine also changes, such as yellowing or reddening, which is a diseased phenomenon.

3. Put a thermometer into the rectum to measure body temperature. Normal body temperature is 37.5 - 39.5 degrees Celsius. If the body temperature exceeds or falls below the normal range, it will be diseased. Cattle whose body temperature is below normal usually suffer from massive blood loss, visceral rupture, toxic diseases, or are about to die. If fever alternates with non-fever in diseased cattle, they may suffer from chronic tuberculosis, coccidiosis or trypanosomiasis.

4. Observe the overall attitude of the cattle. Healthy cows have agile movements, flexible eyes, wagging tails and shiny fur. If cattle are found to have dull eyes, rough fur, arched back, standing still, even shaking and shaking their tails, it is a sign of illness.

5. Nose-looking glasses. Healthy cattle, regardless of the weather, hot and cold, day and night, have perspiration beads in their noses, which are red. If they are dry and without perspiration, they are sick.

6. Weighing and recording of milk production, and comparing the differences in milk production at different times. Healthy dairy cows produce milk more smoothly. If the milk production drops suddenly, it is a sign of illness.

The basic principle of dairy cow medication is: generally, dairy cows are sick, if not very serious, do not use antibiotics. Even with antibiotics, most of the time they are injected rather than taken orally. Because cattle are polygastric animals, when taken orally, antibiotics will kill some beneficial microorganisms in the rumen of cattle, resulting in an imbalance of microbial communities.

In order to prevent disease and promote growth, cow babies are usually fed with antibiotics before the rumen microbial community has been established. But stop feeding as long as seven or eight months old; inject cows as few times as possible. Dairy cows are timid and very sensitive. Even if strangers visit the cattle farm, they will be frightened and reduce their production. The impact of injection is greater. Therefore, vaccination, try to use joint vaccines. After the injection, the milk production of cows will decrease, especially in the hot summer weather.

Generally, when the cow's disease is not very serious, it will wait until two months after stopping milk for treatment. Cattle breeders should strive to keep the cows well in these two months so that they can devote themselves to a new round of milk production with a healthy body.

Employees in dairy farms should not drink raw milk and pay attention to preventing zoonoses, such as Pasteurellosis and tuberculosis. Before the invention of pasteurization, countless people in Europe contracted tuberculosis by drinking raw milk or eating dairy products. But since pasteurization has been widely used, it has been rare for people to get the disease from drinking milk.
