Big difference in temperature between autumn and winter

The function of regulating the body temperature of the newborn pigs is not perfect, and the resistance to cold is poor, and the ambient temperature is required to be high. The suitable temperature for one-day-three-day-old is 30°C-32°C, and the suitable temperature is from 4 days to 7 days. The suitable temperature is 28°C to 30°C, 15 days old and 30 days old is 22°C to 25°C. Cold temperatures can cause pigs to cause colds, pneumonia, or freeze-throats, so be careful to maintain a suitable ambient temperature. Must set up the pig incubator, use the infrared lamp or electric thermostat warm plate to keep the pig lying in the above position. 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 pigs should be brought back to the incubator and placed in a warm place every time after they are born within 1 to 3 days.

The temperature difference between day and night after the Mid-Autumn Festival is growing. The doors and windows of nursing houses and nursing houses should be properly closed at night according to the situation. The temperature of the pig house should be kept above 22°C. The temperature of the pigs in the newly weaned pigs 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 are also prone to occur in autumn and winter. Frequent spraying of insecticides is necessary to prevent insects from biting the herd. Pigs with rickets should be promptly treated. Pigs can be fed regularly with oxytetracycline at a rate of 600 grams per 1,000 kg of feed.
