The weather in spring is changeable, and the temperature difference between morning and evening is large, which may have a certain impact on the physiological state of the sow. For example, a sudden drop in temperature may cause the sow to become cold, while a temperature that is too high may make the sow feel uncomfortable, affecting her appetite and rest. In addition, spring is also the season of high incidence of a variety of infectious diseases, such as swine fever, foot-and-mouth disease, blue ear disease, etc., which can have a serious impact on the health of sows.
1.Keep warm and ventilated
Although the temperature has risen in spring, the climate is changeable, and the temperature difference between morning and evening is large, so it is necessary to keep the temperature in the pig house constant, and pay attention to cold and warm when the weather is cold. At the same time, it is also necessary to do a good job of ventilation to exhaust the dirty air in the house and maintain the freshness of the air in the house. But in spring, it is still necessary to pay attention to the relationship between warmth and ventilation, and choose a time of day when the temperature is higher for ventilation.
2.Feeding management
In the spring when the climate is changeable, pig feeding management technology should be strengthened, the epidemic of pig production should be effectively controlled, and the efficiency of pig production should be improved. For example, the delivery room should be thoroughly cleaned, rinsed, and disinfected. After the sow farrows, scrub the sow's nipples, udders and abdomen, squeeze out a few drops of milk one by one, and then let the sows breastfeed.
3.Disease prevention
Spring is the season of high incidence of many infectious diseases, so it is necessary to strengthen disease prevention efforts. For example, vaccine immunization can be carried out, and the immunization of each pig should be done in strict accordance with the immunization program, and the vaccine should not be missed to avoid the failure of epidemic prevention.
4.Disinfection of enclosures
Disinfection is a very important step in the management of pig farms in spring, because the temperature rises in spring, which is the season for the mass reproduction of pathogenic microorganisms.
In general, spring weather has a certain impact on sow farming, but as long as appropriate measures are taken, these effects can be effectively reduced and the health of sows can be guaranteed.
