What to pay attention to when raising pigs with a large temperature difference between day and night
In autumn, the climate is dry and changeable, with a large temperature difference between day and night, especially in late autumn when the climate is even more changeable, so keeping piglets warm is particularly important. In addition, blood-sucking insects (such as mosquitoes) are also more active in autumn, and swine eperythrozoonosis is also prone to occur and spread.
1. Newborn piglets have an imperfect thermoregulatory function and poor resistance to cold, and require a higher ambient temperature. The suitable temperature for piglets aged 1 to 3 days is 30°C to 32°C, for those aged 4 to 7 days it is 28°C to 30°C, and for those aged 15 to 30 days it is 22°C to 25°C. Low temperatures can cause piglets to catch colds, develop pneumonia, or freeze to death, so it is important to maintain a suitable ambient temperature. A piglet warming box must be provided, using infrared lamps or electric thermostatic heating plates to keep the lying area of the piglets at the above temperatures. In late autumn, attention should be paid to closing doors and windows and sealing gaps to prevent drafts from invading. The temperature of the farrowing house should be kept above 20°C. During the first 1 to 3 days after birth, piglets should be carried back into the warming box after each nursing and placed in a warm place. Wind direction and wind speed self-recording instrument / wind speed and wind direction recorder, wind direction and wind speed meter, rainfall recorder.
2. After the Mid-Autumn Festival, the temperature difference between day and night becomes increasingly large. The doors and windows of the nursery house and farrowing house should be properly closed at night according to the situation, so that the temperature in the pig house is kept above 22°C, and the temperature inside the house for newly weaned piglets should be kept at around 26°C.
3. Intensive pig farms are prone to outbreaks of porcine epidemic diarrhea, transmissible gastroenteritis of swine, and pseudorabies in winter. Therefore, in late autumn, all sows should be injected with the combined vaccine against porcine epidemic diarrhea and transmissible gastroenteritis of swine; before mating, sows should be injected with inactivated oil-emulsion vaccine against pseudorabies and vaccines such as swine fever, and the immunization method is the same as the routine immunization method. Breeding boars should also be vaccinated with the above vaccines in late autumn. In addition, respiratory diseases such as swine enzootic pneumonia and porcine contagious pleuropneumonia, as well as swine eperythrozoonosis, are also very likely to occur in autumn and winter. Insecticidal drugs should be sprayed frequently to prevent insects from biting the pig herd. Pigs with sarcoptic mange should be treated promptly, and the pig herd can be regularly fed oxytetracycline at a ratio of 600 grams per 1,000 kg of feed.
