A lighting system for illuminating a swine comprising a first plurality of lights , a second plurality of lights and a third plurality of lights , and a control system, the lighting system comprising: one or more controllers configured to increase a first voltage supplied to the first plurality of lights to a first threshold voltage to illuminate the first plurality of lights to provide a first light to the swine for a first predetermined period of time, the first light having a first color characteristic, the one or more controllers are also configured to increase a second voltage supplied to the second plurality of lights to a second threshold voltage to illuminate the second plurality of lights to provide a second light to the swine for a second predetermined period of time with a second color characteristic different than the first color characteristic, wherein the second color characteristic promotes a predetermined biological response in the swine for a second predetermined period of time, the predetermined biological response being attracting the swine to food; wherein the second predetermined period of time is less than the first predetermined period of time, wherein the second predetermined period of time is less than one hour; wherein the second light is substantially concentrated within a specified range of wavelength between 400 nm and 495 nm; characterized in that the one or more controllers are also configured to increase a third voltage supplied to the third plurality of lights to a third threshold voltage to illuminate the third plurality of lights to provide third light with a third color characteristic that stimulates the entrainment of a circadian cycle of the swine; wherein the third light is substantially concentrated within a specified range of wavelength between 370 nm and 400 nm. one or more controllers configured to increase a first voltage supplied to the first plurality of lights to a first threshold voltage to illuminate the first plurality of lights to provide a first light to the swine for a first predetermined period of time, the first light having a first color characteristic, the one or more controllers are also configured to increase a second voltage supplied to the second plurality of lights to a second threshold voltage to illuminate the second plurality of lights to provide a second light to the swine for a second predetermined period of time with a second color characteristic different than the first color characteristic, wherein the second color characteristic promotes a predetermined biological response in the swine for a second predetermined period of time, the predetermined biological response being attracting the swine to food; wherein the second predetermined period of time is less than the first predetermined period of time, wherein the second predetermined period of time is less than one hour; wherein the second light is substantially concentrated within a specified range of wavelength between 400 nm and 495 nm; characterized in that the one or more controllers are also configured to increase a third voltage supplied to the third plurality of lights to a third threshold voltage to illuminate the third plurality of lights to provide third light with a third color characteristic that stimulates the entrainment of a circadian cycle of the swine; wherein the third light is substantially concentrated within a specified range of wavelength between 370 nm and 400 nm. <EOS>
