Summer management of birds is important as heat stress causes adverse effects on the performance, the welfare and productivity of broiler farming. Ideal temperature for successful broiler rearing is 18-28 °C and above 30 °C temperature heat stress starts. Following are the steps of summer management of broiler chicken:
A) Housing management:
- House should have good insulation with support of foggers and cooler systems.
- Increased air movement over the birds by cooler, fan/exhaust to produce wind chill effects which cool birds even without drop in the house temperature.
- Shed design and construction should not allow direct sunlight inside the house.
- Thatching of roof with paddy straw or sugarcane leaves will reduce temperature inside the shed.
- The roof should be painted with white wash to reflect light.
- Plantation of tall branched trees around the sheds can reduce the radiant heat.
B) Water management:
- Supply of plenty of clean & cold water
- Use water sanitizer in drinking water to control infection.
- Cover water tanks with wet gunny bags to avoid direct exposure to sun.
- Increase frequency of watering.
- Cover water pipeline with wet gunny cloths.
C) Feeding management:
- Offer feed during cooler part of the day (early morning and evening) only.
- Feed supplements like vitamin C, E, B2, B6, B12 and trace minerals should be given.
- 20- 30% extra vitamins and trace minerals should be added to feed.
- Addition of ammonium chloride, potassium chloride and sodium bicarbonate improve performance of broilers birds.
- Pelleted feed should be given.
D) General management:
- Depth of litter should be 2-3 inch on floor. Stir the litter regularly to prevent caking.
- 10% extra floor space should be provided in summer.
- Overcrowding of birds must be avoided.
- Shifting, transportation, debeaking and vaccination should be done during cool hours only.
- Birds severely heat stressed may be dipped in cold water for 2-3 minutes keeping their head & neck above water level.
- Use foggers in shed reduce the shed temperature up to 5-10°C.
- The house should be situated away from other buildings in order to facilitate free movement of air.
