“…Light program, and the type and quality of litter in broiler fattening affect physical activity rhythm of feeding of chickens. It is believed that the broilers exposed to more frequent alternation of light and dark periods are more active during periods of light (Ferrante et al, 2006) and that the rhythm of feeding in moderate photoperiod changes so that the peak of the food consumption is reached at the beginning and at the end of the light period (Gordon, 1999). The most pronounced differences are between continuous or almost continuous and intermittent light programs.…”

Light program and quality of litter are important for forming of the environment and have a direct impact on the performance and welfare of broilers. In conditions of short-photoperiod, the welfare of broilers is improved, but they lead to reduced body mass. In this sense, the aim of this study was to investigate the effects of two light programs and two types of litter on production and carcass characteristics of broilers of different genotypes. Trial was conducted on 800 day-old chicks of genotype Hubbard classic and Ross 308. For litter, two types of materials were used - chopped straw and sawdust, the same thickness. Chickens were exposed to light program with constant moderate photoperiod (LP1), and gradual extending of the photoperiod (LP2). The results suggest that the LP2 would slow down the initial growth of broilers and the occurrence of compensatory growth, without any negative effect on the final body weight and production efficiency. LP1 effect was confirmed in increasing the yield of the carcass. The effects of both light programs are not the result of their major influence, but they are consequence of the interaction with genotype. From the point established of production and carcass parameters in treatments with litter, the criteria for selection of materials for the litter should include indicators of welfare, as well as the availability and cost of certain materials.

“…Increasing dark period reducing the energy requirements of chickens as a result of reducing their metabolic rate (Classen, 2004). It was believed that chickens kept on more frequent alternation of light and dark periods would be more active during periods of light (Ferrante et al, 2006) and that the rhythm of feeding in moderate photoperiod changed so that the peak of the food consumption was reached at the beginning and at the end of the light period (Gordon, 1999).…”

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.
