Animal husbandry management

Solar radiation: to be reduced as much as possible 

  • Provide shaded areas at the pasture. 
  • Limit the translucency on the south side of the building. 

Ventilation: allows to reduce significantly the heat stress of the animals. 

  • Promote natural ventilation of buildings 
  • Mechanical ventilation: a ventilation of 2.5m/s decreases the THI by 5 points. 
  • Caution: it is often irregular in the building. Think about it well to avoid groupings of animals in certain places. 
  • Misting also helps to reduce heat stress: it should be combined with ventilation to limit humidity in the building

Ration distribution 

  • Avoid food intake in the hours before heat peaks. Distribute the ration early in the morning or at the end of the day
  • Distribute several fresh rations per day to stimulate ingestion
  • Limit direct sunlight on the ration to avoid overheating. 


  • In the barn 10% of the cows must be able to drink at the same time: provide 10 to 13 cm of available water per cow and at least one water point for every 20 cows. 
  • Water flow rate for unrestricted drinking troughs: 15 to 20L/min minimum. 
  • Water temperature < 25°C. 
  • Water must be readily available and as close as possible to the pastured grass
