Thermal stress and its impacts on livestock ruminants ?
With global warming, livestock animals are increasingly often subjected to thermal stress.
Thermal stress is a stress experienced by an organism when it can no longer manage excess heat and maintain an optimal body temperature, under the pressure of excessive ambient temperature and relative humidity.
Temperature Humidity Index for Dairy Cows
| Comfort zone | |
| Stress zone | |
| Mild to moderate stress | |
| Moderate to severe stress | |
| Severe stress |
The optimal ambient temperature for ruminants in a livestock building is between 5 and 15°C. Starting at 22°C, the relative humidity of the living area affects their stress levels, especially from 40% relative humidity onwards: this is referred to as thermal stress. :
-> from 53% relative humidity, the ITH increases to 68 and dairy cows are in heat stress.”>from 53% relative humidity, the THI increases to 68 and dairy cows are in heat stress.
Consequences of thermal stress on the animal
Behavioral adaptations
Animal discomfort :
- Hyperventilation
- Hypersalivation
- Decreased general activity
- Prolonged standing
Performances drop :
- Reduced production
- Disruption of reproduction
Impact économique
Exemple : 100 dairy cows at 30L/Cow/day having experienced 30 days of heat stress over the year
-
- Production loss (milk quantity and quality) : -12 000 €
- Reproductive costs : -10 000 €
- Veterinary costs : -5 000 €
Total loss of earnings : -27 000 € / year
Parameters to be controlled in buildings at risk of thermal stress
-
- THI > 68
- THI duration > 68
- 24-hour THI max value
Presentation of ZenCow® range
ZenCow® is a range of IoT solutions for monitoring, measuring, analysing and acting on the risk of heat stress in ruminant livestock buildings.
-> Connected tools : sensors and actuators
-> A dedicated server
-> Connectivity between tools : wireless communication to connect tools to the server and the user
-> Data analysis applications with several optional features
Presentation of ZenCow® sensor
ZenCow® sensor is a global solution composed of a sensor associated with a dedicated application.
THI sensor
Features :
- Reliable measurement and secure, continuous recording of temperature, relative humidity, and THI
- Visualization of instant THI and 24-hour maximum THI on the sensor screen
- Visual alerts on the screen in case of thermal stress
Dedicated application
Features :
- Free download from Apple Store, Google Play, and PC
- Bluetooth connection with phone and computer
- Vizualization of measured data in an exportable table
- Graphical visualization of thermal stress level
Visualizing data on a phone for one sensor
Visualizing data on a computer for multiple sensors
ZenCow® sensor tool’s benefits
– Simple to use and install
– Interactive
– High Tech at reasonable price
For the breeder :
Thermal stress awareness tool
– The THI critical for dairy cows (68) is much lower than that of humans (75), so if the farmer is overheated, his cows have been suffering for longer !
For livestock advisors :
Continuous monitoring tool for THI, temperature, and relative humidity data
– Data export via the PC application to collect data from multiple sensors for analysis and comparison.
ZenCow® Box
ZenCow® Box is a dynamic tool, complementary to the ZenCow® sensor, which allows data continuously recorded on the sensor to be collected and sent back to the server.
Features
ZenCow® Box with ZenCow® Server
- Remotely view data from sensors connected to the ZenCow® Box via the server
- Be alerted by SMS in the event of thermal stress in the building
- Take remote control of the building’s climate
Features
ZenCow® server
3 types of user accounts
- Breeder account : for tech-savvy breeders who care about their animal’s comfort
- Advisor account : for advisors of breeders equipped with ZenCow® Box
- Compte auditeur : for expert advisors on livestock building climate and animal comfort
ZenCow® Box Benefits
For the farmer :
Remote monitoring and action tool for their building to manage the risk of thermal stress
-> SMS alert in the event of a passage into a stress zone and connection to the server via their “farmer” account to view data and influence the building’s climate if it is equipped with ZenCow® Box actuators
For livestock advisors :
Remote consultation and analysis tool for ZenCow® sensor data
-> View data from multiple farmers equipped with ZenCow® Box on the server (via the “advisor” account)
-> Data monitoring and analysis using included or optional applications (monitoring and graphical analysis, technical monitoring, economic monitoring)
-> “Auditor” user account to purchase a ZenCow® Box and independently conduct a thermal stress risk audit in the building.
The ZenCow® Box tool consists of :
1 control box
to act as a relay between the sensors and the server
1 or more repeaters
to send sensor data back to he control box (up to 300 m range)
1 or more actuators (optional)
to control the building’s climate control systems (fan, mist, manual curtain)
is a range of tools developed, produced and marketed by :
