New research from the University of Queensland and the Queensland Alliance for Agriculture and Food Innovation (QAAFI) has revealed that changing the diets of pregnant sows could be key to improving animal welfare by easing heat stress.

Heat stress in dairy cattle is probably the most overlooked seasonal problem here in New Zealand.

As temperatures rise globally, heat stress is becoming more common among cows too.

Heat detection is a challenge in any season, but autumn calvers know that cold and wet weather slows cows down, making heats harder to call with confidence.

As temperatures soar, farmers are being urged to review feed plans and consider what supplements could help reduce the impact of heat stress on their cows.

Dairy cows in all regions are affected by heat stress during summer. The comfort zone of a cow is 4-20°C, about 10-15° lower than the comfort zone of a human.

Heat stressed cows eat less with a consequent drop in milk production, says Jenny Weston, president of the dairy cattle branch of the New Zealand Veterinary Association.

It's been a long time since this writer went to a pop concert, but the young people down our way tell me that if it gets too hot for the seething masses in the mosh pit, the organisers turn on misting cannons to cool them.

With hot summer conditions increasing the risk of heat stress in herds, choosing the right supplementary feed can help farmers turn down the heat in their cows' says SealesWinslow.
