Civcivler, iki aydınlatma programının [Sabit Aydınlatma (SB): 16 saat aydınlık, 8 saat karanlık; Kesikli Aydınlatma (KS): 4 saat aydınlık, 2 saat karanlık] uygulandığı farklı odalara yerleştirilmiştir. Her bir aydınlatma grubu iki ayrı yerleşim yoğunluğunda [Normal Yerleşim Yoğunluğu (NY): 12 broyler/m2, Yüksek Yerleşim Yoğunluğu (YY): 20 broyler/m2] beşer tekrar olacak şekilde deneme düzeni oluşturulmuştur. Deneme 42. günde sonlandırılmıştır. Piliç göğüs eti pH’sı üzerine yerleşim sıklığının etkisi önemli (P0.05). But eti a* renk kriteri bakımından ise aydınlatma programlarının etkisinin önemli (P KW - Broyler KW -  pH KW -  Renk KW -  TBARS KW -  Yerleşim  sıklığı. N2 - Present research was conducted to determine the effects of various lighting programmes and stocking density on colour, pH and TBARS parameters of meat in broilers. A total of 320 male chicks (Ross 308), one day old, were used in the study. Chicks were kept in different rooms where two lighting programs [Constant Lighting (CL): 16 h light, 8 h dark; Intermittent Lighting (IL): 4 h light, 2 h dark] were applied. Experimental design was consisted of two lighting programs and each lighting group had two stocking density subgroups [Normal density (ND): 12 broilers/m; High density (HD): 20 broilers/ m], five replicates each. The experiment lasted for 42 d. Effect of stocking density on breast meat pH was found to be significant (P CR - Apeldoorn E., Schrama J., Mashaly M., Parmentier H., 1999.
