Precautions for the use of heat preservation lamp
Heat preservation lamp is the most commonly used heating equipment, and the key is to select the appropriate wattage. For newborn piglets, the temperature of the floor under the lamp should be 35-37 degrees Celsius. If the piglets are overheated, they will be driven away, and there will be more opportunities to get close to the sows, which will increase the risk of being crushed to death.
the hanging height of the heat preservation lamp should be determined according to the temperature of the pig's activity area (measured by thermometer or felt warm and comfortable), and the distance between the pigs standing under the heat preservation lamp and their backs should be more than 15cm. In winter, it is not recommended to use the heat preservation lamp with too low power. If the temperature is good with low power, it is necessary to shorten the height of the lamp from the ground, and it is easy to burn the pig if it is too close to the pig.
