There is a large temperature difference between day and night in autumn. The function of regulating the body temperature of newborn piglets is not perfect. The resistance to cold is poor and the ambient temperature is required to be high. The suitable temperature for 1 to 3 days is 30 to 32°C, and the suitable temperature is 4 to 7 days. It is 28°C to 30°C, and the suitable temperature for 15 to 30 days is 22°C to 25°C. If the low temperature causes the piglet to cause a cold, pneumonia or to be frozen, care should be taken to maintain the proper ambient temperature. Must set the piglets incubator, with infrared light or electric thermostat warm plate to keep the piglets lying in the above temperature. In the late autumn, we must pay attention to closing doors and windows to block the gap and prevent thieves from invading. The temperature of the nursing house should be kept above 20°C. The piglets should be brought back to the incubator and placed in a warm place every time they are breastfeeding for 1-3 days.
The temperature difference between day and night after the Mid-Autumn Festival is getting bigger and bigger. The doors and windows of nursery houses and nursing houses should be properly closed at night according to the situation, so that the temperature of the pig house should be kept above 22°C, and the temperature of the newly weaned piglets should be kept at about 26°C.
Intensive pig farms are prone to porcine epidemic diarrhea, transmissible gastroenteritis, and pseudorabies in winter, so all sows should be injected with porcine epidemic diarrhea and transmissible gastroenteritis secondary vaccine in late autumn. Before sows are vaccinated, vaccines against inactivated oil emulsion vaccines and swine fever vaccines against pseudorabies vaccine are injected. The immunization method is the same as the routine immunization method. Boars should also be vaccinated separately in late autumn. In addition, respiratory diseases such as porcine asthma, porcine contagious pleuropneumonia and Eperythrozoonosis in pigs occur easily in autumn and winter. Frequent spraying of insecticides is necessary to prevent insects from biting the herd. Pigs with rickets should be promptly treated. Herds can be fed regularly with oxytetracycline at a rate of 600 grams per 1000 kilos of feed.
