Abstract
A total number of 180 one-day old broiler chicks was distributed into factorial design in 2 light sources (fluorescent and light-emitting diodes, LED) and 3 metabolizable energy (ME) levels (low, medium or high) to study carcass characteristics and some bone measurements. Six birds from each experimental treatment (3 males and 3 females) were slaughtered to evaluate carcass and tibia bone measurements. The results indicated that:- Light source and level of dietary ME did not significantly affect carcass yield, giblets and total edible parts percentages.- There were no significant differences between treatments on percentages of inedible parts (blood, feathers, head, gastrointestinal tract and inedible body oranges, abdominal fat) or total inedible parts.- Breast and drumstick percentages showed significant differences, independent on level of dietary (ME).- Tibia diameter, tibia Seedor index and tibia robusticity index, showed significant differences, independent of dietary ME level. It could be recommended from this study that LED lighting in broiler farms and medium dietary ME level could be used with broilers to reduce production costs and improve breast yield.
