dc.description.abstractThe purpose of the present study was to measure performance and carcass yield from broilers maintained on different photoschedules and to compare electricity savings. Day-old 430 broiler chicks from an Avian × Peterson strain cross were used as research materials. There were four lighting treatment (LT) groups. All groups were kept under 231:1D from to 7 days. Four pens were randomly assigned to each of four light treatment groups: 1) 1L:1D, 2) 1L:2D, 3) 1L:3D, and 4) 23L:1D from 8 to 48 days. It was found that there were statistically significant differences for body weights (BW) between different lighting treatment groups at 42 days (P<.05), but that there were no differences with respect to BW between LT groups at 49 days. Feed efficiency values of groups 1, 2, 3, and 4 were estimated at 2.003, 1.987, 1.972, and 2.080, respectively. There were no statistically significant differences among treatments for mortality rates at 49 days of age. But mortality rates of the third and fourth groups were numerically bigger than those of the first and second groups. Mortality rates of the third and fourth groups were estimated greater than standard mortality rate values. The incidence of leg problems was influenced by lighting treatments. There were significant differences with respect to the weights of different parts of the carcasses (P<.01) and no differences for the percentages of carcass parts except in breast percentage between LT groups (P<.05). The carcass weights of first and second groups were found to be heavier than those of the other groups (P<.05). The amounts of electricity used by research groups 1, 2, 3, and 4 during the 49-day rearing period were determined to be 16.3, 12.2, 10.2, and 27.5 kW/h respectively. It has been conluded that continuous lighting treatment in broiler rearing has had no benefit in broiler performance.en_US
