Soaring summer temperatures in Pakistan cause significant production losses in poultry flocks. Discover proven strategies to keep your birds cool, comfortable, and productive.
Pakistan's summer months bring intense heat, with temperatures regularly exceeding 40°C in many regions. For poultry producers, this period represents one of the most challenging times of year. Chickens are particularly vulnerable to heat stress because they lack sweat glands and rely entirely on panting and behavioral changes to dissipate body heat.
Recognizing Heat Stress
Signs that your birds are experiencing heat stress include:
- ›Increased panting and open-mouth breathing
- ›Wings held away from the body
- ›Reduced feed intake (birds avoid eating during the hottest part of the day)
- ›Increased water consumption
- ›Reduced egg production and egg quality (thinner shells, smaller eggs)
- ›Elevated mortality, especially in broilers approaching market weight
Environmental Management Strategies
Ventilation: Ensure your housing has adequate cross-ventilation. Tunnel ventilation systems that create a wind chill effect are highly effective in reducing effective temperature by 4–8°C.
Evaporative Cooling: Evaporative cooling pads combined with exhaust fans can reduce air temperature by 10–15°C in dry conditions. They are less effective in high-humidity environments.
Insulation: Insulating roofs and walls significantly reduces radiant heat gain during peak afternoon hours.
Stocking Density: Reduce stocking density by 10–20% during summer months to decrease metabolic heat production per square metre.
Nutritional Interventions
- ›Electrolytes: Supplement drinking water with sodium bicarbonate, potassium chloride, and ascorbic acid to compensate for electrolyte loss through panting.
- ›Vitamin C: Supplementing at 200–500 mg/kg feed reduces the cortisol response to heat stress.
- ›Energy-Dense Diets: Shift energy sources from carbohydrates (which generate more metabolic heat) to fats during summer.
- ›Feed Scheduling: Provide the bulk of daily feed in the early morning and late evening when temperatures are lower.
