| Abstract | ||||
| The aim of the experiment was to study the influence of lighting programmes on compensatory growth and carcass criteria of broiler chickens. A total number of 120 (one hundred twenty) Ross broiler chicks, one day old were equally divided into 3 treatments of 40 chicks each and further divided into 4 replicates (10 chicks/ replicate). The experimental lighting regime treatments were as follows: continuous, light stimulation and intermittent lighting. The results showed that the birds exposed to T1, and C achieved the highest BW and BWG compared to birds exposed to intermittent lighting. During the period from (0-6) wks of age, birds in groups (C) and (T1) achieved an increase in BWG and improved FCR than the group in (T2). In conclusion results suggested the application of a light stimulation better performance minimizing electricity costs. | ||||
