In a factorial experiment, the effect of three levels of feeding regimes and two levels of lighting schedule were investigated using 480 day-old male Hubbard chicks. The broiler chickens were randomly distributed over two rooms consisting of 4 replicates of 20 birds for each of three treatment groups. From 3 to 12 days of age treatment groups were either allowed ad-libitum access, 90% or 80% to feed. From 12 days of age until 42 days of age all birds were allowed ad-libitum access to feed. The lighting schedule for day 12 onwards in one room was a 23h light (L): 1h dark (D) lighting schedule (CL) and another room with an intermittent lighting schedule (IL, 1L:3D) from 8 AM until 8 PM . The results indicated that feed intake and feed conversion ratio of birds reared in the IL schedule were significantly lower than CL , at growth and total period of experiment (p0.05). Relative growth rate and production (PI( in the IL were higher than CL schedule (p %> http://jcpp.iut.ac.ir/article-1-711-en.pdf %P 363-374 %& 363 %! %9 Research %L A-10-2-711 %+ %G eng %@ 2251-8517 %[ 2007
