ABSTRACT

The present study was conducted to observe the effect of light source and different
photoperiods on the growth rate and feed efficiency in broiler chicks during February to March at
Pantnagar. Initially, the day old chicks in group “A” (n= 288) were exposed to fluorescent light
of 30-40 Lux and chicks in group “B” (n= 283) were exposed to incandescent light of 120-150
Lux for 24 h continuous light during first week of experiment. In the 2nd and 3rd week, they were
exposed to 23 h Light (LL) and 1 h Dark (DD) (LL 23: DD 1). In the 4th and 5th week, birds from
group “A” were divided into four groups (n= 65 each) and exposed to LL 23: DD 1, LL 20: DD
4, LL 18: DD 6 at 15-20 Lux and natural photoperiod of LL 13: DD 11 at 50-70 Lux. The
results indicated that the fluorescent light of 30-40 Lux during first three weeks of experiment
showed significant increment in growth rate and improve feed conversion efficiency compared to
the birds maintained in the incandescent light of 120-150 Lux. The last three weeks experiment
indicated that, the 4-6 h of dark phase helps to improve the production performance in birds
compared to 1 h or 11 h dark phase.
