Self-cooling barn for live pigs and a cooling method thereof

Abstract

The invention belongs to the field of pig breeding, and particularly relates to a self-cooling barn for live pigs and a cooling method thereof. The barn comprise a water storage bin arranged at a bottom of the barn, wherein an upper end of the water storage bin is provided with a plurality of elastic mechanisms protruding out of the bottom of the barn, a bottom of the water storage bin is providedwith a cleaning mechanism, a right side of the cleaning mechanism is connected with a water storage chamber through a pipeline, a pump is connected to a right side of the water storage chamber through a pipeline, a fan is arranged above the water storage bin, a spray head is arranged below the fan, an upper end of the spray head is fixedly connected with an output end of the pump through a pipeline, an exhaust pipe and an exhaust pipe are arranged below the elastic mechanism, a movable switch is arranged at one end, far away from the water storage bin, of the exhaust pipe, and an exhaust portis arranged at one end, close to the movable switch, of the exhaust pipe. The barn can automatically cool the live pigs and effectively save water resources.

Description

technical field [0001] The invention belongs to the field of pig breeding, and in particular relates to a pig self-cooling barn and a cooling method thereof. Background technique [0002] The normal production performance of pigs requires a suitable ambient temperature. When the weather is hot in summer, high temperature will reduce the feed intake, pork quality, reproductive performance of sows, and semen quality of boars, and cause heat stroke; High, the breathing rate of pigs is accelerated in order to dissipate body heat, the metabolism is affected, the appetite is reduced, and the feed intake is significantly reduced, resulting in reduced productivity. If the ambient temperature increased to 25°C and 30°C, the feed intake decreased by 10% and 35%, respectively. It is reported that at 28-35°C, the daily gain of growing and finishing pigs of 15-30kg, 30-60kg and 60-90kg is 6.8%, 20% and 28% lower than the expected daily gain, respectively. [0003] In order to avoid the...

AI Technical Summary

Problems solved by technology

[0003] In order to avoid the impact of high temperature on live pigs, some intensive pig farms are equipped with air-conditioning systems. According to the actual situation, water curtains, dripping, drafting, spraying and other methods can be used to adjust the temperature of the pens. However, the air-conditioning systems have a large demand for electricity. , it is inconvenient for some free-range farmers to use; some farmers use artificial water spraying to cool down the pigs, but artificial water spraying not only wastes water resources, but also cannot guarantee continuous observation and monitoring of the environment. The timely cooling of pigs is not only based on inaccurate judgments, but also excess waste water remains in the pen, which is extremely detrimental to the growth and health of pigs
