This work was conceded to study, the effect of some light
treatments (type and program) on productive performance
and some meat constituents of Fayoumi chickens during
summer season under hot climatic conditions of Upper Egypt.
Three hundred and sixty chicks, fifteen weeks old; were randomly
divided into six experimental groups (6 groups, each group was
divided into three replicates/ 20 birds each).Group 1, the chicks
were exposed to continuous common light program (12h light: 12h
dark/day) (with intensity 10 luxes) and was considered as a control
(C); Group 2 (Tl), the chicks were exposed to intermittent
common light program (6h light:6h dark) each 12h. of day; Group
3 (T2), the chicks were exposed to biomittent common light
program (30 minutes light: 30minutes dark) of each hour of day;
Group 4 (T3), the chicks were exposed to continuous flash light
program (12h light: 12h dark/day); Group 5 (T4), the chicks were
exposed to intermittent flash light program (6h light:6h dark) each
12h. of day; Group 6 (T5), the chicks were exposed to biomittent
flash light program (30 minutes light: 30minutes dark) of each hour
of day. Chicks were reared under the same managerial, feeding
and hygienic conditions throughout the experimental period. During
of the experiment body weight (BW), body weight gains (BWG),
feed consumption (FC), feed conversion (FCR), carcass
characteristics and meat analysis were estimated. Flashed light
groups caused elevation of body weight, body weight gains and
feed intake significantly compared to control, while there wasn't
significant difference between groups for feed conversion ratio.
Flash lighting programs improved carcass characteristics compared
with those exposed on common lighting groups. Flash lighting
program increased moisture percentage and reduced fat
percentage in meat (P<0.05). It can be concluded that applying
the flash light regime tend to improve all measurements studied
without any side effect on Fayoumi chickens during growing period.
