The animal husbandry inherits from the past, and the former is connected with the planting industry and the latter with the processing industry. It is the main role of large agriculture . The output value of animal husbandry in developed countries in the world accounts for more than 50% of agricultural output, and even exceeds 70%. In China now and in the future, animal husbandry is an important pillar of the rural economy, an important way for farmers and herdsmen to increase their income, and an important part of the development of modern agriculture in the construction of a new countryside.
Great progress has been made in China's animal husbandry development. The scale of animal husbandry production has been continuously expanded, the total amount of animal products has increased significantly, and the quality of animal products has continued to improve. Especially in recent years, with the implementation of the policy of strong agriculture and benefiting agriculture, the animal husbandry industry has shown an accelerating development momentum, and the production mode of animal husbandry has undergone a positive change. The scale , standardization, industrialization, and regionalization have accelerated. At present, the output value of animal husbandry has accounted for 34% of China's total agricultural output value. In areas where animal husbandry is developing rapidly, animal husbandry income has accounted for more than 40% of farmers' income. China's animal husbandry has played a vital role in ensuring the stability of urban and rural food prices and promoting farmers 'income. Many local animal husbandry has become the pillar industry of the rural economy and has become the main source of increasing farmers' income. A large number of outstanding brands of animal husbandry continue to emerge. Has made positive contributions to the development of modern animal husbandry.
However, it also has the characteristics of low scientific management level and low production efficiency. Scientific management of large-scale pastures is becoming increasingly important. Through timely and accurate collection, processing, storage, and analysis of ranch information, not only will it provide first-hand data for management of the ranch, but it will also make scientific predictive analysis and decision-making, and ultimately achieve intelligent and scientific management of animal husbandry management.
The emergence of Internet of Things technology makes it difficult to manage large-scale farming
Through sensors , electronic ear tags, collars and other equipment, around the production and management of facility-based livestock and poultry farms , real-time online collection of farm environment information (CO2, NH3, H2S, temperature, humidity, dust, light, etc.), and integrated transformation Existing farm environment control equipment, feed feeding control equipment, etc., the breeding manager can grasp the farm environment information and individual signs of livestock and poultry in real time through the farm monitoring center or through information terminals such as mobile phones, PDAs, and computers. And according to the monitoring results, the corresponding equipment can be automatically / remotely controlled to achieve intelligent production and scientific management of livestock and poultry farms, and finally achieve the goal of healthy breeding.
1. Feeding management.
1. Environmental control:
Install smart sensors in the barn, collect CO2, ammonia, H2S, air temperature, humidity, light intensity, wind speed and video, etc., and send them to the breeder's mobile phone, PDA, computer and other information terminals through wired or wireless, and grasp the farm in real time Environmental information, and according to the monitoring results, can remotely control the corresponding equipment to automatically open windows for ventilation, spray cooling, adjust lighting, etc., to achieve the goals of management automation, healthy breeding, energy saving and consumption reduction. Such as Yixing in Jiangsu, Jiahe in Hunan, and other intelligent pig farms , and 1 million intelligent laying hen farms in Huanghuang, Hubei, to realize automatic detection, transmission, reception, and automatic regulation of the environment in the farm.
2. Fine breeding:
Large-scale breeding farm enclosure construction and breeding machinery and equipment can provide conditions for fine breeding. Relying on the Internet of things computer technology, automated quantitative feeding has now been applied in China. When the cow passes the milking canal, the ear number, weight, and physiological status data are automatically recorded and transmitted to the computer system, which analyzes and calculates the optimal feed intake of the cow, and directs the feeder to automatically distribute feed and statistics. For example, the feeding monitoring system of Ningxia Yinchuan Aote Information Co., Ltd. sets the formula for different herds, and queries the details of each feeding time, loading point loading point, unloading pen, and unloading amount. Used by other cattle farms.
3. Intelligent management:
In addition to automatically adjusting the temperature, light, and ventilation of the farm environment monitoring, intelligent farms can also realize intelligent feeding: the water supply and food distribution can be programmed according to time, and the intelligent host feedbacks information based on time nodes or detectors, and quantifies regularly. Ration food. Intelligent feces collection: When the feces fall to the overhead platform to reach a certain amount, the intelligent host can notify the cleaning equipment to collect the feces. Intelligent cleaning: The cleaning device can start cleaning regularly to avoid bacterial infection. Therefore, using a new type of intelligent farming can not only sit in the office to achieve breeding management, but also save labor and energy conservation and emission reduction. For example, the annual production of more than 20,000 heads at the Aotian Farm in Daxing District, Beijing can save 50,000 tons of water per year.
4. Video surveillance:
By installing video surveillance, you can understand the current and period of time audiovisual data, understand the livestock activities in the field, and the work of the breeders. There are door magnets, human sensors, infrared dual detectors, infrared beams, sound and light alarms, front-end detectors, etc., which can remind illegal hosts to call or send messages to the host through the alarm host. Entry monitoring of off-site personnel improves the safety level of the ranch.
Second, reproduction management.
1. Dairy estrus monitoring system:
It consists of a pedometer fixed on the thigh of the cow and a sensor of the milking table. The data of the pedometer and the sensor is automatically identified and exchanged every time you milk, and the pedometer cow's activity is automatically transmitted to the computer database. Analyze whether you are in heat. Kappa value of estrus monitoring is 0.706 (bred cattle) to 0.850 (breeding cows), which can not only detect estrus, but also breed management, judge estrous period and monitor follicular cysts, ovarian stagnation, pregnant cattle estrus, hoof limb disease.
2. Sow estrus monitor:
The "boar effect" principle combined with Internet of Things technology for estrus monitoring has been produced and applied. When the herd is in estrus, it will contact the boar in the electronic estrus detection station. The system records the ear tags and the number and duration of contact with the boar. .
3. Delivery and piglet management:
In addition to the installation of wireless high-definition cameras to understand the activities of livestock on the farm, sow birth and piglet management can also be carried out. For example, video information can be released before delivery to transmit monitoring data. A sow delivery alarm device installed on the delivery bed can send a detection signal when the piglets are ejected from the birth canal, and call the breeder for delivery management. Similarly, using a thermal infrared sensor to monitor the piglet movement zone in the farrowing limit pen, once the piglets are detected in the movement zone, the breeder is notified through a pager. The use of machine vision technology and thermal infrared sensor monitoring for sow farrowing detection and piglet management has been applied.
3. Animal disease surveillance.
1. Routine monitoring:
Use embedded chips and other intelligent acquisition devices to collect physiological status indicators such as body temperature, heartbeat, ruminant, belching, feces, urine data, and changes in blood cells and enzymes. These data are transferred to a computer system to analyze the health status, monitor the disease, and detect The preliminary physiological analysis of the received physiological data, combined with clinical diagnosis, early treatment of livestock to prevent large-scale outbreaks of the disease.
2. Alarm monitoring:
The RFID real-time positioning system (RTLS) is used to help farmers locate individual cows in their herds. Even when grazing far away, they can analyze the behavior of the cows and detect the precursors of disease in time. If the feeding time of cows with ketemia is reduced, abnormal gait, aggressiveness, or roaring may occur. When the reader receives the tag signal, it is transmitted to the central management system for alarm. Using this system for analysis, it is generally possible to find the disease one week in advance.
3. Diagnosis of the disease:
The Internet of Things hardware and software technology promotes the development of biometrics, sensors, digital medical equipment, and rapid diagnostic instruments for animal disease. The application of immunosensors, DNA, microorganisms, tissues and other biosensors can directly diagnose such as Brucella sheep Diseases such as disease, Newcastle disease, bird flu, and petite ruminant disease can also be used to determine the titer of immune antibodies, and these data are directly transmitted to terminal systems such as PAD through computers, which is convenient for managers to carry out animal disease prevention and control.
In the process of promoting the scale, intensification, standardization, automation, industrialization, marketization, and intelligence of animal husbandry production, not only animal husbandry and veterinary technology and factory hardware conditions, but also a large number of computer information application software development, animal husbandry The development, application and supporting promotion of the Internet of Things technology will become a new topic in modern animal husbandry production, which should attract great attention from animal husbandry departments, scientific research institutes and scientific and technological personnel at all levels. Interdisciplinary professional research and application of animal husbandry, veterinary medicine and information technology will become the future Research focus.
