Optimize your broiler production

All organisms ranging from small bacteria to chickens and humans, have a biological clock. What does this biological clock do, in case of a chicken? The biological clock influences the chicken’s behaviour and its internal processes. The biggest ‘Zeitgeber’, or regulator of this biological clock, is the daily change in illuminance, which is the difference between day and night: dusk and dawn.
LIGHTING & THE BIOLOGICAL CLOCK
Influencing this ‘Zeitgeber’ via lighting management will influence the biological clock of the chicken, which will influence the chicken’s behaviour and its’ internal processes.
First of all, lighting management can be used to stimulate feed intake (and consequently growth) and to optimize feed to gain ratio. How? Light stimulates (feeding) activity: the longer the photoperiod, the higher the feed intake. Be aware though, light intensity should be high enough to pass a certain threshold in order to stimulate activity.
Secondly, an uniform light spread is important to prevent broilers from clustering. Clustering, the intense grouping of broilers, can be caused by shadows and bright spots. Clustering can lead to footpad lesions and breast blisters, which increases mortality and decreases animal welfare and uniform growth, and thus profit.
As can be seen in the figure below, an even light distribution prevents broilers from clustering and stimulates uniform growth. The PULSA and CORAX products are just the right products to ensure uniform light spread.
