One is cold. The suitable growth temperature for pigs was 32°C~35°C for newborn pigs, 20°C~22°C for nursery pigs, and 15°C~20°C for medium and large pigs. The effect of low temperature on pig growth and weight gain is more serious. When the temperature of the pig house is lower than the lower limit of the suitable temperature, the daily weight gain decreases by 17.8 grams for every 1°C decrease; if the temperature decreases below 4°C, the weight gain rate decreases by 50%. Increase feed consumption by more than double. Therefore, the winter barn should be strengthened to keep warm, reduce the metabolic consumption of pigs, and improve feeding efficiency.
Second, fear of the tide. When the ambient temperature in the house is low, the relative humidity is high, which seriously affects the pig's production performance, especially the piglets. Piglets in pig houses with high relative humidity in winter have an average weight gain of about 48% lower than that of the control group, and are prone to diseases such as diarrhea and enteritis. The suitable growth humidity for different pigs was 50%-70% for piglets, 70% for finishing pigs with 40-80kg, 80% for finishing pigs with 80-110kg, and 55%-80% for breeding sows. Houses can be dampened and kept dry by measures such as ventilation, increased light, warming and bedding.
Three afraid of cold. Winter drinking water and feed temperature have a close relationship with pig growth and health. When the water temperature and material temperature are 0°C, the temperature of the water and the material is raised to a body temperature of 39°C, and the pig body consumes 682 to 878 kcal of heat energy, which means that 0.5 to 0.75 kg of concentrate feed is used every day. Consumptively consumed to maintain body temperature. Therefore, it is better to feed warm and warm water for piglets and sows in winter. The water temperature is maintained at about 37°C.
Four afraid of the wind. Pigs in the winter are most afraid of "dragon style" and "thief wind" will not only reduce the temperature, but also more easily cause swine cold, stroke, rheumatism and other diseases. The pig house in winter must block wind tunnels, hang straw curtains, paste windows, close doors and windows, prevent rat holes, cracks, gaps, broken tops, doors, window seams, etc. in the circle from blowing into the “thief windâ€, affecting normal pigs. Growth and development.
Five are afraid of disease. If the pig house is cold in winter, has high humidity, poor sanitation, and poor ventilation, the pig is susceptible to disease. Therefore, we must strengthen the feeding and management, keep the ventilation and cleanliness of the pens, clean and dry, and regularly disinfect the pens, it is best to use the flame disinfection method. At the same time to achieve "five observations", that is, the concept of form, view of the spirit, view of food intake, observation of excrement, observation of breathing, once the pig disease should be diagnosed in time, as soon as possible isolation treatment.

Mobile video monitoring and alarm system is a set of intelligent system for security to enter the civilian field. This system integrates mobile phone monitoring and mobile phone anti-theft alarm systems. When illegal people break into the restricted area, the system host will immediately call and send SMS or email to the designated users! Users can view the image of the monitoring area with their mobile phones or computers as soon as they receive a phone message.
It eliminates the worries of false alarm of traditional monitoring system and traditional alarm system! The system integrates wireless door magnetic, wireless smoke detector and other wireless alarm accessory information, effectively improving the civilian characteristics of the monitoring system. Shenzhen Kate Technology Co., Ltd. is specialized in mobile video monitoring products. The supporting mobile phone software of this product, namely Kate Guardian, can be linked to mobile text messages or phone calls with video monitoring and home alarm. This product is also a smart home security monitoring anti-theft system: the system is a network but can be completed independently without a computer! The local memory can record video for 24 hours, and you can view and operate all the monitoring images in your home through your Internet phone or computer in other places.
The system has its own wireless alarm module, which can be matched with wireless door magnets, probes, smoke detectors and other wireless alarm trigger devices. When someone breaks into the monitoring defense area, the system will automatically call, send SMS and email to the designated four mobile phone users, and will also generate audible and visual sirens locally. After receiving the alarm call and information, the remote user can view the monitoring picture through the Internet mobile phone or computer, control the camera rotation angle and focus, and deploy and remove the alarm system through the mobile phone, while starting the mobile phone video recording function and handling the alarm.

After work or when going out, you can open your computer or mobile phone at any time to view the real-time image of your home, communicate with your family face to face, learn about your family, and take care of your family remotely; When the thief steals while no one is at home, the automatic signal can be sent to the community monitoring center in time, and the residents can be notified by mobile short message, email or telephone. All this can be easily achieved through the home video monitoring system. As early as 2004, the total output value of China's video surveillance industry application market had reached 15.1 billion yuan, an increase of nearly 23% compared with 12.3 billion yuan in 2003, and growing at an annual rate of about 20%. According to the survey of the analysis institution, with the accelerating pace of life, the demand for family users' sense of security is gradually increasing, and the requirements for family monitoring and security are also increasingly mature.
As the video monitoring system plays an important role in protecting security and preventing crime, the growth of personal users' demand for family security will certainly drive the development of residential monitoring system. The demand for video surveillance from ordinary consumer households is becoming an emerging market for video surveillance applications, and is expected to show significant growth in the next few years.
