| What problem does the tool address?: | The topic of heat stress is well researched worldwide. However, there are hardly any studies that relate to conditions in Switzerland. In particular, little is known about how dairy cows on pasture react to heat stress. A survey has shown that farmers often overestimate the threshold for heat stress. Heat stress can already occur at around 16 degrees Celsius, depending on humidity, wind and solar radiation. Cows under heat stress eat less to avoid additional heat from digestion. The effects of heat stress on milk yield become apparent with a delay of about three days. In the medium term, heat stress can also affect the fertility of cows. During heat stress, cows increase their breathing rate to release body heat. If they can no longer do this, their body temperature rises. An increased body temperature of over 38.5 degrees indicates heat stress. In behaviour, cows show heat stress in so-called grouping behaviour, among other things. Fleeing animals generally show this behaviour in stressful situations. They stand close to each other, do not eat and do not chew again. |
| What solution does the tool offer?: | Measures against heat stress in grazing cows include bringing them back into the barn, providing drinking troughs and shade, grazing in the cooler hours, timely observation and use of warning apps as well as insect protection. Fans, misting and showers can be used when housing cows indoors. When converting or building new stables, the heat factor should also be taken into account. Recognising the right moment when one's own herd begins to suffer from heat stress requires good observation and experience. |
