It is very important to use environmental controller in pig raising equipment

We all know that high yield can bring high benefit. In order to obtain good breeding results, farmers often need to control from multiple aspects of breeding, such as pig breeding, feeding, disease prevention and control, pig house environment and so on. Farmers all know the importance of selection, feeding and disease prevention and control. However, some farmers will ignore the importance of the environment of pigsty, which is absolutely unacceptable. Today, let's learn with Xiaobian about the importance of the environment in the pig raising process and how to use appropriate pig raising equipment for environmental control.
First, maintain proper temperature and humidity.
Under normal conditions, when the temperature is between 16 ℃ and 21 ℃ and the humidity is between 65% and 75%, the growth condition and speed of the pigs are the best. Too high and too low temperature, too wet or too dry pigsty will have a very bad impact on the growth of pigs. Especially in summer, there are many hot and rainy days. If the pig house is hot and wet, it is easy to reduce the intake of pigs, which will affect the normal development of pigs, and even cause death.

Secondly, keep good ventilation.
If the air condition in the pigsty is not good, the carbon dioxide and water vapor exhaled by the pig, together with the increase of ammonia and hydrogen sulfide and other harmful gases produced by the decomposition of feces and urine, will cause chronic poisoning of the pig group in serious cases, and there are many hot days in summer. Only by maintaining the good ventilation condition in the pigsty can it be conducive to the heat dissipation of the sealed pigsty, and the dust, harmful gases in the air The microorganisms are dispersed to create an environment suitable for the growth of pigs.
It can be seen that appropriate pig raising equipment is used in breeding, such as the installation of Pratt & Whitney intelligent environment controller to control the temperature, humidity and ventilation of the environment in a unified way, or the installation of Pratt & Whitney steel fans and ventilation windows when building pig houses.
