Monitoring and management system for automatic drinking water of pigs

Abstract

The invention discloses a monitoring and management system for automatic drinking water of pigs. The system includes a flow meter, a pressure gauge, an electric control valve, an electric pressure-reducing valve, an alarm, a controller, an ear tag, a code scanner, a power supply, a communication converter, a host computer, a displayer, a mouse and a keyboard; the system allows real-time monitoring and regulation of the flow and pressure of water flowing out of a pig-use water dispenser to be conducted on the computer in an office, and can achieve the functions of flow upper limit alarming, flow lower limit alarming, pressure upper limit alarming, pressure lower limit alarming, water shortage alarming, running water alarming, flow regulation, pressure regulation and recording the instantaneous water intake and cumulative water intake of each pig. The pig farm management efficiency is improved, the labor intensity of workers is reduced, the sewage discharge is reduced, the pollution to the environment is reduced, the sewage treatment cost is saved, and the intensive management of large-scale pig farms is achieved.

Description

technical field [0001] The invention relates to the technical field of livestock breeding devices, in particular to an automatic drinking water monitoring and management system for pigs. Background technique [0002] Drinking water has a major impact on the feed conversion ratio, growth and health of pigs. Drinking water quality not only reduces the bacterial load in the water, but also increases the digestibility and absorption of nutrients in the pig's digestive tract. Under house feeding conditions, a sow with piglets needs to supply 75-100L of water per day, 30L for pregnant sows, boars and finishing pigs, and 15-20L for young pigs and fattening pigs. It is extremely important for weanling pigs to drink enough water in the first 2 weeks after weaning, because high protein diets at this time require a higher water intake to excrete excess nitrogen, so as to ensure feed intake and reduce morbidity. In particular, it is necessary to ensure the supply of water for lactatin...

Problems solved by technology

[0005] If the water flow rate of the drinker is too small, the pigs will not drink enough water; if the water pressure is too high, the flow rate of the drinker will be too fast, which will easily cause water waste and wet the ground; the drinker is relatively delicate and easy to be damaged. Water, for example: in pig farms using iron pipes for water supply, rust will occur in the water pipes in 2 to 3 years. The rust spots will combine with calcium and sediment in the water to form a mixture, which will block the water supply branch pipes and drinking fountains, resulting in insufficient water supply pressure. There may be local water shortage in pig houses, or indirect water shortage. Therefore, at present, it is necessary to manually check the drinking water system 3 times a month; Drinking water for more than 6 hours will lead to overdrinking, and symptoms of "water intoxication" will occur. In mild cases, oliguria and frequent urination, red urine, body temperature drop, rapid breathing, and abdominal circumference increase. In severe cases, appetite loss, vomiting, The feces are thin, the limbs are weak and swimming like paddling, muscle spasms, and even death; if the drinking fountain is damaged, the water will not flow continuously, resulting in waste of water and wet ground, and increase the amount of sewage discharge and increase the treatment cost
