A good internal climate and effective air circulation form the foundation for healthy animals. Poor stable ventilation can have far-reaching, negative consequences:
Poor stable ventilation can have far-reaching, negative consequences:
- An environment that is too warm or too humid leads to decreased appetite in animals. When they eat less, their output and the yield drop.
- A poor internal climate is a breeding ground for germs. A warm, moist environment is the perfect place for bacteria and viruses to infest and multiply rapidly. The animals then run a high risk of infection.
- When heat increases the temperature indoors, this causes stress and restlessness in animals. This can lead to a variety of problems, including claw disorders.
- For cows, heat stress can lead to health problems with udders, decreased fertility, and milk loss.
- Proper stable ventilation enables greater control of the climate in the stable. See the example below;
In the summer, a cow sweats out about 30 litres of water per day and about 15 litres during the winter. When proper ventilation is not present, a cow stable quickly becomes humid, warm, and oppressive. Furthermore, ammonia gases remain in the air. This is an undesirable situation for both man and animal. In addition to all of that, a cow experiences heat stress when temperatures exceed 20 degrees Celsius. A simple formula indicates that the daily milk output of a cow increases by two litres, when the feed intake increases by one kilo. When both man and animal experience discomfort from heat, loss of appetite occurs and milk production decreases accordingly.
Therefore, it is important to properly manage the climate of the stable and adjust it when appropriate. Proper stable ventilation ensures that the cow suffers less from heat stress and will improve the output of the cow. Good ventilation also prevents the occurrence of mastitis, because bacteria in clean air that has had the humidity removed have a lower chance of survival and infecting the animals.
