In the cold winter months, some of the sows reared by free-range households just rushed to the winter. The main cause of slaughter of sows in litters during freezing winter is that they are crushed or frozen by sows, especially within three days after birth. In cold environments, the piglets do not move sensitively, and they are lying or lying on the grass. Sows squat, easily crushed by the sow. It is easy for the piglets to suffer from cold in the cold and will not suck the milk, resulting in freezing and dying. Adaptation temperature of piglet: 1st to 3rd day of age, 30°C~32°C; 4th to 7th day of age, 28°C~30°C; 15th to 30th day of age, 22°C~28°C; 2 months of age ~3 months of age is 22°C.
There are many measures for thermal insulation. In the production practice, according to the specific circumstances, according to local conditions, the following describes several measures: 1. Heater lamp. In general, 50-watt infrared lamps are used for heating in piglets, and the effect is good. The disadvantages are short lamp life and high cost. 2. Nursery or incubator. In sows or maternity wards, a nursery bar is set up, with upholstered grass and an infrared lamp on the hood. It is best to use a covered incubator and hang an ordinary 100 watt bulb to maintain the proper temperature. The free access of piglets also reduces the chance of sows squeezing piglets.
Industrialized pig rearing is carried out throughout the year with a balanced delivery system, and a delivery room is specially provided. The delivery room is equipped with insulation and cold-proof equipment, such as hot blast stove, heating, etc., and the temperature of the delivery room is maintained at 18°C~22°C (the most suitable temperature for nursing sows). . There is a piglet incubator in the corner of the stall to create a warm and comfortable environment for the piglet.
