The primary function of pig heating lamps is to increase the temperature inside the pigsty and provide necessary warmth for piglets.
Pig heating lamps, especially infrared heating lamps, are widely used in pig farms. These lamps are suspended above areas where piglets rest, such as above the farrowing crate or inside the warming area, to provide heat and warmth. Infrared heating lamps typically have power ratings of 100 watts, 150 watts, or 250 watts. The appropriate bulb power can be selected based on the season and ambient temperature, and the temperature can be controlled by adjusting the height of the lamp to ensure the piglets are in a suitable thermal environment. Additionally, infrared heating lamps are simple in design, provide excellent heat retention, and also help prevent skin diseases12.
During winter pig farming, the use of heating lamps is particularly important. Especially in farrowing houses, to prevent piglets from getting cold, the heating lamps in the warming boxes are usually kept on 24 hours a day. If piglets huddle together under the heating lamp to sleep, it indicates that the warming box is not warm enough. In such cases, the perceived temperature for the piglets can be adjusted by changing the height of the heating lamp from the ground3.
In summary, pig heating lamps effectively protect piglets from the cold by providing a suitable thermal environment. Through simple equipment setup and effective temperature control, they ensure the healthy growth of the pigs.
