Abstract:
This study was conducted to evaluate the effect of different LED light color on growth
performance of broiler and compare the performance of broiler reared under two different light
sources and two different light colors. A total of 120 day-old Lohmann Meat (Indian River)
broiler chicks were reared for 28 days at Sher-e-Bangla Agricultural University Poultry Farm,
Dhaka. Chicks were divided randomly into 3 experimental groups of 4 replicates (10 chicks
with each replication). Among the three treatment groups, one group kept under Incandescent
light as control (T
0
) and the other groups kept under red LED light (T
1
) and white LED light
(T
2
) were treatment groups. During the experimental periods of 4 weeks, feed intake, body
weight gain, feed conversion ratio (FCR), survivability, flock uniformity values were
calculated. Growth performance parameters were significantly (P<0.05) affected by
experimental light. Birds were reared under white LED light gained superior body weights
(1916.84±16.03g) compared to control (1807.36±14.50g) and red LED light (1854.38±30.93).
Feed conversion ratio was comparatively better (P>0.05) and dressing percentage was
increased (P<0.05) in birds reared under white LED tube light. The weight of breast, back,
thigh, drumstick and giblet was significantly (P <0.05) high in T
2
group as compared to T
1
and
control (T
0
) group. In addition, the present study showed that the different color LED light in
different groups had no significant effect (P>0.05) on relative weight of neck, wing, heart, liver,
gizzard, spleen and proventiculus. Survivability was no significantly (P>0.05) higher in T
2
and
T
0
group compared to T
1
group. However, the higher flock uniformity (76.5±7.81%) was found
in T
2
group compared to T
1
(70±7.07%) and T
0
(71.95±10.97) group which was statistically
insignificant (P>0.05). In case of cost benefit analysis, net profit was highest in T
2
group than
the other groups. The study therefore concluded that, white LED tube light could be a better
alternative source of light than Incandescent light in terms of growth performance of broiler
chickens, economics and energy saving.
