Abstract

The present study was designed to determine the effects of lighting regimes on the growth performances and carcass characteristics of Bronze turkeys reared in intensive conditions. Turkeys were reared under three lighting regimes (group 1, 12 h; group 2, 18 h; and group 3, 23 h.). In the experiment, the live weights of the turkeys (male+female) in groups 1, 2 and 3 were found to be 4578±142, 4630±131 and 4942±139 g respectively at the end of a 16-week period. The live weights during the 16-wk period were found to be affected (P0.05). These values were 3347±152, 3389±141 and 3554±197 g; and 71±1, 70±3 and 71±1 % for groups 1, 2 and 3 respectively. Twelve hours lighting per day proved to be enough for the Bronze turkeys. However, 23 hours lighting per day appeared to have no important negative effect on the performance of the turkeys.
