Calves and heifers shouldn’t have to sweat
UNIVERSITY PARK, Pa. -- Heat abatement during high temperatures is important for keeping calves and heifers comfortable and growing.
Some tips for helping your herd deal with hot weather may include:
• Decrease solar load by providing shade
• Heat abatement structures do not have to be new or expensive. A pre-existing structure can be altered to provide air exchange and increase natural ventilation.
• Increase convective cooling
• This may be as simple as clearing a side wall and removing the metal to provide air exchange
• Increase evaporative cooling capabilities
• Install mechanical ventilation - for example have high motor fans circulation fans to increase cooling and air velocity
• Fans should be mounted over the cows
• Add evaporative cooling
• Increase water space - provide an additional drinking station
• This may include installing timed sprinklers in stalls
• Sprinklers provide direct cooling for cows while using a low pressure system and can be added in in the holding area or return lane
• Be proactive and consider heat abatement techniques to implement in your facility.
