Pig growth, reproduction, and health are all significantly impacted by the color of the light used in pig farming. The effects of various light hues on pig growth are as follows, along with some recommendations:
1. A red light
Function: It is thought that red light, which has a wavelength of roughly 600–700nm, helps pigs grow. This is especially true at night when the pigs are exposed to red light, which can lower their stress response, enhance their food intake, and quicken their pace of weight gain.
Application scenario: It is appropriate for use in fattening pig homes, particularly when it comes to supplying red light illumination at night, which promotes the silent and rapid growth of pigs.
2. Blue illumination
Function: Blue light, which has a wavelength of 400–500 nanometers, has a positive impact on pigs' immune systems and metabolism. However, too much blue light can make pigs anxious and excited, which can hinder their ability to sleep and grow.
Application scenario: To control the pigs' biological rhythm, it can be used during the day in conjunction with white light or natural light.
3. White illumination
Function: Pigs' growth, development, immunity, and reproductive performance can all be fully enhanced by white light, also known as full spectrum light, which mimics natural light. Pigs' development rate and feed conversion rate can be considerably increased by 15 percent with the right amount of light and duration (12–16 hours per day, for example).
Use case: It can be used in piglet and sow houses, particularly in enclosed pig houses with inadequate lighting. Pigs' growing conditions can be enhanced by adding more white light.
4. Light that is ultraviolet
Function: The antibacterial and vitamin D synthesis-promoting properties of ultraviolet light (wavelength of around 200–400 nanometers) can improve pigs' immune systems and bone formation. On the other hand, too much UV light can lead to skin irritation or other health issues.
Application scenario: Although direct irradiation of pigs for an extended amount of time is not recommended, it is appropriate for usage in disinfecting regions or during certain times.
5. Light that emits infrared
Function: Infrared light (wavelength above 700 nanometers) is mainly used for local heating, especially in piglet incubators, which can provide a warm environment and promote the growth and development of piglets.
Application scenario: Suitable for use in cold seasons or pig pens as an auxiliary heating light source.
Best choice: Red and white light are the preferred light sources for promoting pig growth. Red light is suitable for nighttime use to reduce stress; White light is suitable for daytime use and simulates natural light environments.
Attention: The intensity and duration of light should be adjusted according to the growth stage and needs of pigs to avoid negative effects of excessive or insufficient light on their health , you can choose pig grow led light on http://www.benweilight.com
