| Abstract | ||||
| The current investigation was designed to evaluate the effect of light regimens on broilers performance, carcass parameters, lymphoid organs, blood constituents, health parameters of Sasso broiler chicks. Two hundred and seventy chicks were randomly divided into 3 equal groups 90 chicks each (24hr continues light, C; 12hr continues light plus 12hr flash light, CF and 24hr flash light, F). All experimental chicks were housed in floor pens from one day till six weeks of age. All environmental and administrative provisions were the equivalent during the trial time. The obtained results showed that lighting regimens significantly affected growth performance, abdominal fat, plasma constituents, antioxidant markers, health parameters and performance evaluation. However, there were no significant effect on feed consumption and lymphoid organs. In addition, birds raised under continues+flash lighting program had the highest performance. Therefore, the continuous plus flash lighting program is highly recommended for Sasso broiler chicks during fattening period. | ||||
