Dairy Cow Hoof Horn Quality

Hoof horn quality in dairy cows directly affects lameness risk, with nutrition, genetics, and flooring all playing important roles.

Key Facts

Poor hoof horn quality increases risk of white line disease and sole ulcers
Biotin supplementation at 20mg/day improves horn quality over 6-9 months
Zinc and methionine also contribute to healthy hoof horn formation
Concrete flooring abrasion accelerates horn wear and increases lameness risk
Genetic selection for claw health traits is gaining traction in breeding programmes

Welfare Considerations

Soft or brittle hoof horn leads to painful lameness, often chronic. Good nutrition and flooring management can prevent substantial suffering.

What You Can Do

Provide biotin and mineral supplementation appropriate to herd needs
Assess flooring types and use rubber matting where possible
Include claw health in breeding selection criteria
Trim hooves regularly and treat lesions promptly
