The function of the piglet to regulate body temperature is not perfect, and it is poor in cold stress. The newborn piglet is in an environment of 13°C to 24°C, and the body temperature drops by more than 1.7°C for 1 hour. Piglets are sparsely coated with subcutaneous fat and energy reserves are limited. The blood glucose level is 100 milligrams per 100 milliliters of blood. The temperature of the environment is low, the newborn piglets are physically regulated by limited body temperature, and because the mechanisms of the cerebral cortex to regulate body temperature are not fully developed, they cannot be chemically adjusted. 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 most suitable temperature for piglets is: 28°C~32°C for 1~7 days; 25°C~28°C for 8~30 days; 23°C~25°C for 31~60 days. At present, the cold insulation measures for piglets generally have the following types: First, thick dunnage Thick dunnage is a traditional way of keeping warm, and is often 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 thickness of the mat grass up to 30 to 40 cm, the outer nail on the grass to prevent grass mat scattered. When the temperature is 10°C~15°C, the temperature of the berm grass can reach above 21°C. This method is economic and easy, saves labor, saves grass (grass), and keeps warm and damp. When this method is adopted, the bedding should be replaced promptly, dry fresh grass be added, and the column should be kept dry. Second, heating and heating Fire heating is a traditional method of insulation. There are two types of flue ducts and charcoal stoves. There are two kinds of flue ducts, ground flue and underground flue. When using coal and other fuels for heating, no matter which type of heating method is used, in addition to the prevention of fire, it is also necessary to eliminate the harmful gases in the column and prevent poisoning. Third, infrared heat lamp The infrared heat lamp is widely used. The method is: using an infrared light bulb to hang on the nursery lying on a nursery shelf or in a warm room to keep the piglets warm and warm, and to adjust the height of the infrared heat lamp 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. When using a wooden fence or iron fence as a partition wall, two litter piglets cannot share an infrared heat lamp. Fourth, piglet insulation board electric constant temperature warm plate surface temperature 26 °C ~ 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. V. Far-infrared heating Piglet incubator The incubator is 100 cm in length, 60 cm in height, and 50 to 60 cm in width. The far-infrared heating plate is connected to a controllable temperature element and placed on the lid of the tank. The temperature of the incubator is adjusted according to the piglet's age. In order to facilitate disinfection and cleaning, the lid can be removed and the material of the box is made of waterproof material. β-Nicotinamide MononucleotideNMN,NMN Power In Gels,Cosmetics Raw Materials NMN Yuyao Lifespan Health Technology Co., Ltd. , https://www.yuyaolifespan.com
