In winter, the temperature is low, the weather is cold, and the cows have a large amount of heat, which affects the milk production. In order to ensure the continued high yield and stable production of dairy cows, it is necessary to further strengthen dairy cows' winter management.

1. Keep warm and keep warm Insulation of dairy cows is an important measure to improve the environment and strengthen winter management. The optimum temperature for black-and-white cows is 8 to 16°C. Closed thermal insulation barn can not reach the requirements at night, can increase the stocking density, cows can be closed when the cowshed idle part. Or use simple plastic shed culture, can increase the temperature of the cowhouse. As long as the feeding is good, the milk production will not drop.

2. The use of artificial lighting with a closed warm house cattle, the lack of light, can increase the artificial light, so that not only increase the temperature of the cowhouse, but also increase milk prolactin, increase milk production. The method is to light 16 hours dark and 8 hours proportional circulation. According to the test, the daily milk production per cow can be increased by 10%. The cows are shed with plastic film, although there is natural light during the day, but it is necessary to make up for 16 hours in the short night, and for 8 hours in the night, sticking for 2 to 6 weeks, it can be effective.

3. Feeding dairy cows with high levels of feed nutrition Winter and spring weather is cold, the temperature is low, the body of the cow is very hot, the heat needed for warming should be increased, and the amount of mixed concentrate should be increased by 5% per day to maintain good sensation in order to guarantee the cows. The normal milk production and increased milk production.

4. Drink to feed scientific straw silage and vegetables, potatoes, beets and other juicy feed rich in nutrients, cows love to eat. In particular, sugar beet contains oxidizing enzymes, which can effectively increase the milk production of dairy cows and is a good feed for milking cows. The number of drinking cows is not less than 3 times a day. And be sure to drink close to body temperature (38 °C ~ 40 °C) of warm water. Avoid drinking cold water, ice water.

5. The method of raising milk production by alternation raising method is to gradually reduce the amount of concentrate feed in the feed of cattle, and gradually increase the amount of green and rough feed, if the amount of milk produced is still not reduced, etc. Increase the concentrate. This repeated replacement of fine, rough feed feeding method can stimulate the cow to eat more green, rough feed, improve feed conversion rate and milk production.

6. Increase the number of milking to increase the number of milking cows. It can increase the milk production of dairy cows. Experience has shown that the maximum number of milkings in a day is 4 times, usually 2 or 3 times. Squeeze a few times a day, can strengthen the function activity of the gland of the mammary gland, accelerate blood circulation, metabolism, also raised the milk production quantity of the cow.

7. Hot compresses and massages the breasts The breasts and hot compress breasts are maintained in hot water at 53°C to 56°C, which allows the breast blood vessels to expand rapidly, increase the amount of blood flowing to the breasts, strengthen the synthesis of milk fat, and stimulate the breasts to discharge more milk. Breast massage during pregnancy can promote breast development, increase milk production, the effect of the initial distribution of cows is more obvious. Massage the breasts before milking can stimulate the rapid expansion of the breast, easy milking, and more milking. After breast milking, the remaining milk can be squeezed out, which has a significant effect on increasing milk production and milk fat percentage.

8. Brush the cattle body cold in winter, the cow's surface vasoconstriction. If you persist in brushing your body with a brush, you can promote the blood circulation of the cow and have a significant effect on increasing the milk production of dairy cows. The milk yield can be increased by 8% to 10%. The contaminated part should be washed and wiped with lukewarm water, and the area to be washed in winter should be smaller, not to wash the bovine body in a low-temperature environment to prevent the occurrence of a cold.

Intelligent Face Recognition Locks

Hello~Face recognition is a kind of biometric identification technology based on facial feature information. Using a camera or camera to collect images or video streams containing faces, and automatically detect and track faces in the image, and then carry out face recognition on the detected face of a series of related technologies, usually called portrait recognition, face recognition.
Face recognition system mainly consists of four parts, which are: face image acquisition and detection, face image pretreatment, face image feature extraction and matching and recognition.
Face recognition is mainly used for identity recognition. Due to the rapid popularization of video surveillance, many video surveillance applications urgently need a kind of fast identification technology under the condition of long distance and users' uncooperation, in order to quickly confirm the identity of people from long distance and realize intelligent early warning. Face recognition technology is undoubtedly the best choice. Using fast face detection technology, we can find the face from the surveillance video image in real time, and compare it with the face database in real time, so as to achieve fast identity recognition.
