Poultry Heat Stress Management Guide: Smart Summer Strategies to Increase Productivity
What is heat stress for poultry and how does it affect your farm in the summer?
Heat stress in poultry is a physiological condition that affects birds when the ambient temperature rises above their thermal comfort zone (above 25 degrees Celsius), making it impossible for the bird to get rid of its excess body heat.
Heat stress in poultry leads to decreased feed intake, reduced feed conversion rates, poor eggshell quality, and increased mortality. Treatment involves a comprehensive approach that includes mechanical ventilation, feed adjustments, and the use of registered veterinary heat stress medications available through the Drugvet veterinary drug encyclopedia platform.
Summer crisis: Why is heat stress the number one enemy of poultry farmers?
With the extreme rise in temperatures during the summer, the poultry industry faces a critical challenge: heat stress in poultry. Birds, by nature, do not have sweat glands and rely primarily on panting to evaporate water from their lungs to cool their bodies. When high humidity is combined with high temperatures, this mechanism completely fails.
The losses from heat stress in poultry are varied and include:
- Weight loss: The bird stops eating feed to reduce the heat generated by digestion.
- Deterioration of immunity: Heat stress in poultry increases the secretion of the hormone corticosterone, which suppresses the immune system, making the flock susceptible to viral and bacterial diseases.
- Reduced egg production: Heat stress in the summer affects the quality of the eggshell (it becomes thin and brittle) as a result of blood alkalinity and loss of calcium and carbonate ions.
A smart tip from Drugvet:
To prevent summer losses, it's essential to understand the precise composition and active ingredients of medications used to treat heat stress. You can search for registered veterinary drugs and compare products using the DrugvetMaster veterinary drug encyclopedia app.
Diagnostic symptoms of heat stress in poultry
Before starting to develop a heat stress treatment protocol, the engineer and breeder must carefully observe the field symptoms:
- Rapid breathing and opening the beak: to attempt evaporative cooling.
- Birds move away from each other and spread their wings away from their bodies to dissipate heat.
- Excessive water consumption: Water consumption rises to 3 or 4 times the normal rate.
- Watery diarrhea: This results from drinking large amounts of water, which spoils the moisture of the bedding.
- Complete inactivity and lying down: near walls or sources of ventilation.
Scientific and practical solutions for treating heat stress
Treating heat stress requires a five-dimensional plan based on integrated management and documented pharmacological intervention:
1. Adjusting the amber environment and ventilation
The efficiency of the cooling cells and fans must be ensured to increase the air speed above the birds (Wind Chill Effect), which helps to draw heat directly from their bodies.
2. Smart dietary modifications
It is preferable to remove feed from the birds during the hottest hours of the day (from 10 a.m. to 4 p.m.) to avoid the heat affecting digestion. This can be compensated for by providing high-energy, high-protein feed during the cooler hours.
3. Effective drug intervention (heat stress relievers)
Adding specialized chemical compounds and vitamins to drinking water is the cornerstone of treating heat stress:
- Vitamin C (ascorbic acid): Reduces cortisol levels and protects cells from oxidation.
- Electrolytes (replacement salts): such as potassium chloride and sodium bicarbonate to restore the acid-base balance of the blood, which is disrupted by shortness of breath.
- Betaine: It acts as an osmotic regulator, protecting intestinal cells from dehydration and maintaining their vitality during heat stress in poultry.

How does the Drugvet platform and encyclopedia help you manage poultry farms?
After more than five years of preparation and continuous work, Drugvet was launched as the first integrated and specialized platform for veterinary medicines in Egypt, featuring more than 10,000 veterinary pharmaceutical products. This initiative is one of the largest specialized projects in the veterinary pharmaceutical sector in the Arab world, and it represents a valuable tool for every poultry farmer and veterinarian to combat summer-related problems such as heat stress in poultry.
The platform includes an integrated website, a smart application on Google Play and the App Store, as well as a printed paper encyclopedia consisting of three parts totaling about 1700 pages.
Comprehensive data for each veterinary product used to treat heat stress:
The encyclopedia provides you with an accurate and documented database derived from the Egyptian Drug Authority and the Hayel Guide to Veterinary Medicine, and contains:
- The trade name, scientific name, and active ingredient are all listed accurately.
- Pharmaceutical group and pharmaceutical form (powder, liquid).
- Detailed composition and uses of heat stress treatment.
- Doses and withdrawal periods for each type of target animal (fattening, laying, breeding).
- The registration number, type, and storage and handling data are required to ensure that counterfeit and unregistered medicines are avoided.
Veterinary Consultants Department: Direct support for your herd
The platform is not limited to medicines only, but also includes a special section for the most prominent veterinary consultants in the fields of diseases and nutrition of poultry, livestock, fish, and pets.
This section gives you access to consultants’ expertise, their contact information, and the seminars and conferences they participate in, giving you a comprehensive scientific line of defense against heat stress in poultry under the supervision of top experts.
📢 Opportunity for veterinary companies:
The platform provides each company with a dedicated account, allowing them to update their product information, add new heat stress treatment products, and display images and prices after scientific review and documentation. This ensures your products reach thousands of breeders daily. For sponsorship requests and app subscriptions, contact us directly via WhatsApp: 01044442621.
Frequently asked questions about heat stress in poultry
Q1: What is the ideal temperature for poultry to avoid heat stress?
The ideal temperature (thermal comfort zone) for adult poultry ranges from 18 to 22 degrees Celsius. Heat stress in poultry becomes noticeable when the temperature exceeds 25 degrees Celsius, and becomes fatal if it reaches 35 degrees Celsius with high humidity.
Q2: How does vitamin C contribute to treating heat stress in poultry?
Vitamin C acts as a powerful antioxidant, inhibiting the release of stress hormones (such as cortisol) from the adrenal gland, and helping birds to regain their vitality and lower their internal body temperature during heat stress waves in the summer.
Q3: Why does eggshell quality decrease during periods of heat stress?
Due to the heat, the bird resorts to rapid panting, which expels large amounts of carbon dioxide (CO2) from its lungs. This results in a state of "respiratory alkalosis," reducing the concentration of free calcium and carbonate ions in the blood, which are essential components for eggshell formation.
Q4: Should the feeding times be changed in the summer as a form of heat stress treatment?
Yes, absolutely. Feed should be completely removed from the birds' reach two hours before the heat intensifies (for example, from 10 AM to 4 PM). Feed digestion produces a high internal temperature (SDA), and if this coincides with high ambient temperatures, mortality rates will rise dramatically.
Q5: What is the role of betaine in protecting poultry from heat?
Betaine is an excellent osmotic regulator (osmolyte). It helps intestinal cells and internal tissues retain water and moisture within them and prevents them from drying out under the influence of heat stress in poultry, thus maintaining intestinal integrity and nutrient absorption.
Q6: How can I be sure that the heat stress medication I buy is genuine and registered?
You can verify this immediately by visiting the Drugvet website or app and searching by product name or active ingredient. You will then see official registration data issued by the Egyptian Drug Authority, a picture of the product, and its approved dosages to ensure efficacy and safety.
Q7: Is there a printed copy of the encyclopedia of veterinary medicines to keep on the farm?
Yes, the encyclopedia is available in a deluxe paperback edition consisting of three parts, totaling about 1700 pages, containing all the veterinary medicines traded in Egypt and their specifications. It is an indispensable reference for every doctor and breeder in the barn.
