Farms environmental protection air cooling cooler ventilation case

Every year in the summer heat, always due to high temperature stress (terminology) caused by some sow deaths, boar semen quality decline, fat pigs due to the heat to reduce feeding, these effects make it a headache, because the sow is the most important enterprise "assets", valuable, boar semen quality directly affects the production of hogs, which affects the yield and fat pigs, if the normal stalls on the market is not only the production needs, such as if the impact of heat stress, also directly affects its feed-to-meat ratio (term: cost advantage). Normal pen to market is not only the production needs, such as if the heat stress impact, the same direct impact on its feed-to-meat ratio (term: cost advantage), although the original take the installation of sprinkler heads spraying water, as well as the installation of a large number of fans, water curtains for negative-pressure ventilation and cooling, but can not be a fundamental solution to the problem, and gave rise to a series of negative effects, such as in the farrowing room, the sows and the side of the piglets in the temperature needs to be a difference of more than 5 ° C. These methods are not able to Meet the needs of large and small pigs at the same time.
