In anticipation of high temperatures and THI values, specific controls and actions should take place to ensure a smooth transition.
First of all, check that the temperature and humidity sensors are working to avoid any risk of measurement deviation. Cooling systems, such as nebulizers or pad cooling systems, can be tested to avoid a malfunction occuring late in the heat wave period.
For buildings with dynamic ventilation, make sure that the air inlet is always on the cooler side of the building and that the air outlets or extractors are not obstructed or clogged. If necessary, fans can be used to increase air velocity and improve heat dissipation.
Keeping your animals hydrated
In a heat stress situation, the main means of thermoregulation of poultry is the acceleration of the respiratory rhythm. This increases heat loss through evaporation but can lead to an alteration of the animal’s acid-base and electrolyte balance. These changes can lead to respiratory alkalosis.
In this situation, some practices can improve voluntary water intake, preferably with fresh water:
- Frequent purging of lines to ensure water renewal
- Checking the flow rate to detect a possible line blockage
- Enhanced disinfection rate to avoid bacterial development which is favoured by high temperatures
- Water supplementation with electrolytes to support water consumption
