Piglets are sparsely coated with subcutaneous fat, limited energy reserves and poor cold resistance. Therefore, the sows are born in winter or early spring. The piglets must do the insulation work to create a suitable living environment for the piglets. The optimum temperature for piglets is 28 to 32°C for 1 to 7 days, 25 to 28°C for 8 to 30 days, and 23 to 25°C for 31 to 60 days. At present, there are several measures for keeping piglets warm.
1, padding material is a traditional way of insulation, more used in family pigs. The method is: the first day shop 10 cm thick mat grass, the next day to add 10 to 20 cm mat grass, so that the mat grass thickness of about 30 cm. This method is economic and easy, saves labor, heat and moisture. When using this method, the bedding should be replaced promptly, dry fresh grass be added, and the inside of the ring kept dry.
2, using fire to warm the fire heating method is a traditional way of insulation. There are two types of flue gas and coal stoves. There are two kinds of flue gas ducts, ground flue and underground flue. Irrespective of the type of heating used, in addition to preventing fires, harmful gases in the pens should also be eliminated in time to prevent carbon monoxide poisoning.
3, infrared heat lamp The infrared heat lamp is widely used. The infrared light is hung on the nursery shelf where the piglet is lying or in the heat preservation room to keep the piglets warm and warm, and the hanging height of the infrared heat lamp can be adjusted at any time according to the desired temperature of the piglet. This method is simple in equipment, good in heat preservation, and has the effect of preventing and treating skin diseases.
4, insulation board electric constant temperature warm plate surface temperature 26 ~ 32 °C. The product structure is reasonable, safe and energy-saving, easy to use, flexible in temperature adjustment, accurate in constant temperature, and suitable for large-scale factory pig farms.
5, far infrared heating incubator box size is 100 cm long, 60 cm high, 50-60 cm wide. Connect the far-infrared heating plate to the controllable temperature element and place it on the cover. The temperature of the incubator is adjusted according to the age of the piglet. For ease of disinfection and cleaning, the lid can be removed and the box material is made of waterproof material.
When using the above several kinds of heat preservation methods, such as laying grass on the ground, the effect is better. At the same time should pay attention to the humidity and ventilation conditions.
