Evidence shows that pigs have poorer color perception than humans and in particular a reduced sensitivity to the red end of the spectrum. There is little research into the effect of colored lights on pig production. In cases where red light has been used, pigs respond as though in darkness.
Proper lighting benefits both pig welfare and performances and eventually farm performances. This surely makes life better for a pig farmer.
The physiology of the porcine eye suggests that the domesticated pig is best adapted for dim levels of natural light. The pigs have dichromatic vision, in the pig's eye, there are two sets of cones that give the animal peak wavelength sensitivity at 439 nm (blue color) and 556 nm (green color). The photoreceptors in a pig's eye cannot detect the red color (>650 nm).
Since lighting has a strong influence on pig welfare and performance, it is important to ensure an optimal light climate in a pig house. Using Hontech Win's pig farm lighting system with high-quality led lights can significantly improve pig performance.
