Abstract

---

The study was designated to investigate the effect of light color and stocking density on some blood parameters of broilers and layers. A total of 675 Ross 308 one-day-old broiler chicks were used in this study. The birds 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. The birds were randomly divided and housed into 9 wooden sealed pens of 1m² in three replicates for each density 12, 15 and 18 birds/m² in the room. In the second treatment, 180 Isa Brown layers were divided into 5 treatments with an average of 36 birds for each of five color light rooms (16 hours light- 8 hours dark) in three replicates for each density 5 and 7 birds/m² in the room. The results showed a significant interaction (P< 0.05) of light color and stocking density on Red blood cells (RBC) and White blood cells (WBC) under BGL at 12 birds/m² and Platelets (PLT) under 15 birds/m², whereas hemoglobin concentration (Hb) and packed cell volume (PCV) showed a significant difference under BGL treatment. No differences were revealed in all blood traits of layers under different light colors and bird densities except for WBC in layers reared under WL.
