Farmed Cattle Fly Control and Welfare

Fly burden causes significant welfare harm in outdoor cattle, and effective fly control reduces stress, injury, and disease transmission.

Key Facts

Face flies (Musca autumnalis) cause irritation, eye disease, and IBR virus transmission
Horn flies cause up to 70 blood meals per day per animal
Fly avoidance behaviour reduces grazing time and feed intake
Pour-on insecticides, back rubbers, and ear tags are common fly control methods
Ear fly tags reduce fly burden but have environmental contamination concerns

Welfare Considerations

Cattle heavily burdened with flies spend significant energy in avoidance behaviour, reducing time for grazing, resting, and social interaction. Fly-induced eye infections cause chronic pain and vision impairment. Effective fly control protects both welfare and production during the fly season.

What You Can Do

Support welfare standards requiring fly burden assessment in outdoor cattle
Advocate for integrated fly management reducing environmental chemical impact
Choose beef from farms with documented fly control management programmes
