Farmers urged to protect livestock as heat stress risk rises

Agriculture Victoria is urging farmers across the state to take extra care of livestock as summer temperatures continue to climb. The department says the recent heat has increased the risk of heat stress, which can severely affect both animal welfare and farm productivity.

Senior Veterinary Officer Dr Jeff Cave says cattle, pigs and high-producing animals such as dairy cows are particularly vulnerable, while poultry can succumb quickly during extreme conditions. He warns that heat stress can reduce feed intake, slow weight gain, lower milk production and even affect fertility.

Humidity can worsen the effects, making livestock more susceptible even when temperatures are moderately high. Dr Cave advises producers to monitor stock daily and adjust management practices to reduce stress.

Recommended measures include providing unlimited access to shade and cool, clean water, avoiding stock movement during the hottest part of the day, and offering high-quality feed in the cooler evening hours.

Agriculture Victoria says that timely action and regular monitoring can help safeguard both animal welfare and farm productivity, and encourages producers to seek further advice from local veterinarians or Agriculture Victoria staff.
