Mistakes in using automatic pig raising equipment

With the development of economy and science and technology, the farmers see the high profits brought by the use of automatic pig raising equipment, so there are more and more farmers using automatic pig raising equipment. But automatic intelligence does not mean that it is omnipotent. Many farmers have some misunderstandings about automatic pig raising equipment. The wrong way of use will not promote the production and development of pig herds. So let's take a look at the following misunderstandings with Pratt & Whitney's editor. Do you also have them.
1. Select pig breeds from unknown sources
First of all, when some farmers choose pigs, they may not check whether the suppliers have business licenses and whether the health and quality of pigs can be trusted.

2. Poor awareness of health defense of farmers
The environmental sanitation of pigsty is the key to ensure the healthy growth of the pig herd. Before putting the pig into the new pigsty or the old pigsty, the farmers should thoroughly disinfect the pigsty to avoid the existence of bacteria and pathogenic microorganisms. Therefore, the sanitation management of pigsty is very important. Xiaobian suggests that the farmers should have special shoes and clothes when entering and leaving. Do not feed people into or out of the pigsty at will. If there are sick pigs, they should have the sense of rapid isolation and disinfection. In addition, regular disinfection should be carried out.
3. Improper temperature control in pigsty
High temperature is needed to ensure healthy growth of piglets. The first week of piglet birth should be controlled at 25 - 30 ℃. Because the survival rate of piglets is directly affected by the temperature, too low temperature will lead to the temperature drop of piglets, and the resistance is weak, which will cause various diseases, too high temperature will lead to heat effect, heatstroke, so when using the environmental controller, it is necessary to set a proper temperature.
