Abstract
The experiment was designed to find out the effect of different light
intensities on the production performance of broiler chickens. One hundred and
fifty broiler chickens were randomly divided into 15 equal experimental units.
Three experimental units (replicates) were randomly assigned to each of the five
experimental groups. Light treatment T1 (20 lux at first week and 5 lux from 2-6
week) was given to group A, T2 (20 lux at first week and 10 lux from 2-6 week)
was given to group B, T3 (20 lux at first week and 20 lux from 2-6 week) was
given to group C, T4 (20 lux at first week and 30 lux from 2-6 week) was given
to group D, T5 (20 lux at first week and 40 lux from 2-6 week) was given to
group E. Results indicated a non-significant effect of light intensity on body
weight and feed consumption whereas, feed conversion ratio (FCR) was
significantly (P<0.05) affected by light intensities.The birds in group A showed significantly better FCR and fetched more
profit. Mortality rate was the highest (13.33%) in the birds kept under group E.
It can be concluded that energy savers (Compact florescent) may be used in
broiler chickens production at same intensities as provided by other light
sources for economical provision of light.
