This study was designated to investigate the effect of color light and stocking density on immune response of broilers after vaccination against Newcastle disease. A total of 675 Ross 308 one-day-old broiler chicks were used in this study were exposed to white light (WL) as a control , red light (RL), blue light (BL), green light (GL), and Blue – Green mix light (BGL) by a light-emitting diode system (LED) applied for 24 hours daily in separated rooms with light intensity 5 watt/m2 . The birds were randomly housed into 9 wooden sealed pens of 1m2 in three replicates for each density 12, 15 and 18 birds/m2. Vaccination of broilers was performed at 21 days of age by the use of Newcastle (ND) LaSota Strain. At the end of 5 week, 1 birds from each replicate were selected and blood was collected and prepared for Elisa technique. No differences were noted in the titer of antibodies against Newcastle disease in broilers reared under different color lights and densities.
