If pig farms cannot supply their own pigs themselves, or if they want to expand their farming scales, they need to purchase piglets. When outsourcing piglets, selecting healthy piglets also makes a decision. Now, we will introduce the healthy piglets to everyone. :
1, on time: This means that the purchase of pigs should be appropriate, the best choice in the spring. Even if piglets cannot be purchased in the spring due to conditions, they should avoid buying pigs in the lunar calendar in August. During this period, the pigs have the highest incidence and mortality, which is commonly known as “bad Augustâ€.
2, near: There are two meanings. First, if there are ideal crossbred pigs in the local market, they should be purchased locally to avoid infectious diseases and other adverse effects. Second, if it is better to choose the same litter for long-term piglets, it is not easy to raise the same litter in the same circle. The phenomena of fighting, fighting, and biting are all in harmony with one another.
3, ears: to buy ears with piglets. The ear number is a gap in the pig's ear. It was cut by a veterinarian using a thorn tong during the injection of the swine fever vaccine. This pig is not susceptible to swine fever.
4, look at: (1) see the size of the head and the trunk is commensurate. Properly proportioned piglets are normal in development, healthy and disease-free; (2) look at foreheads, piglets with wide and flat foreheads that develop rapidly, and the forehead that is slightly outburst and wrinkles are too much indicates that the old phase, commonly known as “small old pigsâ€, grows slowly; (3) look Eyes, healthy pigs have bright eyes and eyes, and pigs often have red eyes or eyelids; (4) Look at the nose. Healthy pigs have long noses, large nostrils, clean nose, and wet nose; (5) Look at the mouth and the length of the fine pig's fork The mouth is round, the lips are thin, and the upper and lower lips are flush. This kind of pig is not picky eaters and grows fast. 5. Listening: Healthy pigs breathe smoothly and rhythmically, and their calls are loud and loud, and their groans are buzzing. The pigs are squeaking, hoarse or coughing, breathing shortly wheezing, flapping their noses, or breathing in the abdomen. Body tremors.
6, heavy weight: As the saying goes "heavy weight is not clinging to light", buy the same litter of piglets to pick the largest weight. The larger the weight of weaned piglets, the faster the development and the more significant the weight gain. Generally 50-60 days of age piglet weight should reach 10-15 kg, piglets below this weight are generally purchased.
7, see hair: to pick thin, thin, tender piglets. This kind of pig fur is smooth and oily, the skin is pink, the body is good, and it grows fast. The pigs with thick skin, thick hair and old meat are slow. The most obvious feature of sick pigs is thick, unkempt and dull fur.
8. Skin selection: The skin of healthy pigs is smooth and elastic. First of all, we must pick out piglets that are not infested. If swelling, ulcers, and small nodules are found on the surface of the skin, the cause must be identified to prevent infectious diseases.
9, pick belly: choose to eat big belly pigs, this kind of pig appetite, grow fast. Select thoracic and abdominal blood vessels, especially pigs with thick exposed breast veins, loose skin, and short interstitial space. The method of selection is to lift the two hind legs of the pig. If the skin at the bottom of the abdomen (the middle of the breast) frequently swings to both sides, the blood vessels on both sides of the breast are clear, indicating that the skin is loose, the vessels are large, and the body condition is good.
10, check the stool: healthy pig manure round, shiny, urine output and normal color, body temperature between 38-39.5 °C. The pig's feces are dry or pulpy, with bloodshot or mucus, dirt around the anus, less urine and yellow, body temperature below 38 °C or above 39.5 °C.
Network Camera NVR CCTV Kits
The functional mode of NVR technology application is relatively flexible and can meet the functional requirements of today's video monitoring system to a large extent. The small NVR scheme with NVR technology as the core has the advantages of small scale, flexible operation, convenient use, economy and practicality. Its front end mainly supports 8-way 720P high-definition video image access with high-definition video camera, and then realizes the centralized management and real-time storage of high-definition video image information through NVR technology. In addition, this small NVR scheme can also support remote management of video images, preview analysis of video images, real-time upload of gigabit network interface video image data, local preview, video playback and other functions. The small NVR high-definition video scheme has a high overall cost performance ratio, simple system and high operational flexibility. This small NVR high-definition video monitoring system is widely used in the centralized video monitoring field in small areas such as companies, factories, family villas, offices, shops, supermarkets, etc.
With the further increase of functional requirements for high-definition video monitoring system, the video monitoring system is required to have the technical performance of expansion, cascade and standard ONVIF communication protocol. The HD cameras of different manufacturers and brands at the front end of the video monitoring system can be organically interconnected through NVR equipment. In this way, a unified functional integrated LAN can be built through NVR to achieve NVR cascade, expansion and mass storage in the video monitoring system. In addition, a centralized advanced application management technology platform is built at the back end through NVR expansion, which can uniformly manage and configure the NVR device group to achieve multi-user forwarding and various application function services (forwarding/management server group) within the region, mainly including: forwarding server, management server, storage database, on-demand server, advanced client application software and other functional modules. The medium-sized NVR high-definition video system is usually used in the medium-sized high-definition video surveillance projects with routes below 1000. Its advantages are that NVR can achieve distributed layout and centralized and unified storage, and its operation stability is high. The back-end technology platform carries out unified management and application, and can achieve multi-user and multi-level integrated and unified application services. The secondary medium-sized network mainly focuses on the urban video monitoring architecture of district, county or prefecture level cities. It realizes the storage of video image data and the centralized communication management of access to front-end equipment through NVR, thus realizing the storage, management, client video image preview, local decoding on the wall and other service application functions of front-end high-definition camera video. At the same time, it can also be authorized by the provincial video monitoring center, The video image information can be previewed, controlled and shared among clients of different levels of users, fully meeting the normal video monitoring function requirements of secondary users in cities such as prefectures, counties and cities.On the basis of the secondary network structure, a large NVR high-definition video system is built by converging into the primary network through private networks, optical networks, and public service networks. The storage and forwarding services of the primary network are realized through the industrial control NVR, and the redundant and safe backup of the video monitoring system is realized at the same time. This distributed multi-level coordinated back-end centralized management network mode greatly provides the overall function and fault tolerance of the video monitoring system, highlights the ease of operation and reliability of the high-definition video monitoring system based on NVR technology, and meets the flexibility, multi-function performance, sharing Emergency handling and other functional requirements.
NVR technology has been widely promoted and applied in urban safe storage, national security and other engineering projects with its own advantages in many aspects. Driven by market and technology, NVR technology will become the mainstream technology in the field of urban security high-definition video surveillance, with very strong theoretical research and practical application prospects
