Too high or too low temp results in
Too high or too low temp results in slow feathering retarded growth pecking and mortality Behaviour and distribution of chicks under and around brooder is the best guide for judging correctness of temp instead of thermometre.
When Temp is less – chicks will try to hurdle near the source of heat
When Temp is less – chicks will try to hurdle near the source of heat If temp is too high – chicks will go away from source of heat, near to the guard and remain there with dull movements. Even may show panting also. If birds congregate themselves in masses in brooder space it indicates draftiness of weather. If temp is favourable: evenly spread under and around brooder with alert and pleasant movements.
Based on chicks position and movement, adjust temperature.
The height of the brooder at day old stage – 15-30 cm above the litter level.
The height of the brooder at day old stage – 15-30 cm above the litter level. As the chicks grows, the height will be gradually increased and the number of bulbs gradually reduced.
24 hrs. Lighting first 3 days
24 hrs. Lighting first 3 days increase the feeding time, increase weight gain, and improve feathering in broiler. Measured Lux units using Lux meter. For day old broiler chicks, an intensity of 100 lux units at bird’s eye level This can be achieved by providing one 100 watt round bulb at 2 ft height from the floor level for every round brooding.
After brooding an intensity of 20 lux is required for birds which can be achieved by providing 40 Watt tube light at 6 ft. height. Light intensity should be uniform throughout the farm. A tube light emits around 60 lux for 400 sq. ft. at 6 ft height.
