Heat stress reduces daily weight gains.
Even at temperatures from 20°C, the calf’s water and electrolyte balance can become disrupted. What looks like “eating less” in the barn is measurable loss of performance.
What heat in the barn does to calves
Calves have only limited ability to dissipate heat. A sweaty coat,
lethargic animals and declining feed intake are typical warning signs.
Comfort zone quickly exceeded
From around 20°C combined with high humidity, calves can already experience heat stress.
Water and electrolyte loss
Through increased breathing and salivation, the calf loses fluids and minerals.
Performance visibly declines
Lower feed and milk intake slows daily weight gains and vitality.
Tips for hot days in the calf barn:
- Place hutches with sufficient spacing between them in the shade
- Ensure adequate air circulation (fans)
- Avoid stressful situations (e.g., moving, dehorning
or overcrowding) - Adjust feeding (use easily digestible carbohydrates
and increase milk volume and/or concentration) - Adjust feeding times (early morning or late evening)
- Offer an additional electrolyte drink (e.g., BEWI®-SAN Bewilyt)
When the temperature rises,
the drink makes the difference.
How to prepare calves for summer
Three clear levers to keep water and electrolyte balance stable.
Free access to water
Fresh, clean water is the first and most important measure – from day 1.
Reduce heat load in the barn climate
Shade, air movement and reduced stocking density lower heat stress.
Provide electrolytes in a targeted way
An electrolyte-rich intermediate drink quickly and easily compensates for losses.
Your solution: BEWI®-SAN Bewilyt
An electrolyte-rich intermediate drink that is quickly available in everyday barn routines.
AS AN INTERMEDIATE DRINK
