Before the advent of winter, when the climate is cold, good management should be strengthened and play a key role in the growth rate of pigs.
I. Renovation of pig houses
Before the arrival of the cold winter season, a comprehensive inspection and maintenance of the pig house shall be carried out. The collapsed walls and roofs shall be repaired. The open-type pig house shall be constructed with a plastic insulation shed, and the ventilation openings and windows shall be sealed. Hang grass curtains and cotton curtains at the entrance to prevent the cold wind from entering.
Second, keep the house clean, dry, fresh air
In order to keep warm, the temperature in the house is too high, and the excess of harmful gas is stagnated. If the temperature is too high, too much harmful gas will induce the pig's breathing, digestion and other diseases. It is necessary to clean the excrement. Appropriately open the vents to effectively keep the air clean.
Third, increase the temperature inside the house
The temperature in the house is too low and it will produce cold stress on the pigs. The cold stress will reduce the health of the pigs and cause some disease outbreaks. When it is cold, the diarrhea of ​​the piglets will be aggravated and the mortality rate of the piglets will increase. There are a variety of methods, such as the use of coal stoves, heating, hot stoves and other equipment to provide heat and increase the temperature.
Fourth, to feed high-quality full-priced feed, change feeding methods
In winter, it is particularly important to feed the pigs with high-quality full-priced feeds. The pigs have good nutrition, have cold resistance and resistance to themselves, and improve immunity. In winter, long nights are long and pigs have fasting in the evening, so they should be fed again at night. Pigs eat enough nutrient-rich feed to increase daily weight gain and shorten the feed cycle.
