Keep your dry cows cool and LiFT® your cow and calf performance...

Brand new to the market, CoolCalver™ has been developed as part of Cargill’s CoolCow® concept to mitigate the effects of heat stress during the dry period and subsequent effects on the calf.

Thermal stress in dry cows occurs from THI 68 (22oC at 60% humidity). When thermal stress is exhibited during the dry period it can negatively affect both the cow and calf.


As well as affecting animal welfare, thermal stress also leads to:



As well as management practices including ensuring sufficient clean water trough space, shade provision, optimised ventilation, and ensuring good feed management to help maintain intakes, CoolCalver™ has been designed specifically to maintain performance of dry cows during periods of thermal stress.
