Cow brushes and heat stress: supporting dairy cow welfare in warmer weather

Grooming is a natural behaviour for dairy cows, but housed systems do not always provide opportunities for animals to scratch, clean, and stimulate hard-to-reach areas.

Cow brushes help fill that gap by encouraging natural grooming behaviour, helping cows stay cleaner, calmer, and more comfortable while supporting day-to-day herd management.

In modern dairy systems, cow brushes are increasingly recognised as part of a practical welfare-focused housing environment rather than an optional extra, particularly during warmer weather when cow comfort and stress management become more important.


Why grooming behaviour matters in dairy housing

Cows naturally spend time grooming themselves and interacting with surfaces that allow them to scratch and clean hard-to-reach areas. In intensive housing systems, opportunities for this behaviour can be limited.

Cow brushes help replicate this natural behaviour inside the shed. They allow cows to groom safely and comfortably, helping reduce frustration, boredom, and stress-related behaviours.

Access to grooming brushes has also been linked to:

  • cleaner coats,
  • improved hide condition,
  • reduced restlessness,
  • calmer behaviour within the herd,
  • improved overall comfort.

For housed dairy cows, environmental comfort is closely linked to welfare outcomes and feeding behaviour. Small improvements in comfort can have a wider impact across the herd.


How cow brushes help reduce heat stress

During warmer weather, cow brushes can support cooling and comfort in several ways.

As cows use the brush, loose hair, dirt, and debris are removed from the coat. This improves airflow across the skin surface and helps reduce heat retention, particularly during seasonal coat changes.

Rotating brushes also provide a gentle massaging effect that encourages circulation and relaxation. Research has shown that grooming activity can support thermoregulation and reduce stress indicators in housed cattle.

In practical terms, cows with access to brushes are often calmer and more settled during periods of heat and humidity.

Cow brushes may also help reduce behaviours associated with discomfort, including:

  • pacing,
  • bunching,
  • excessive standing,
  • agitation in crowded areas.

When combined with effective ventilation and good shed airflow, brushes can contribute to a more stable and comfortable housing environment.


Practical benefits of cow brushes in dairy sheds

Improved hygiene:

Warm weather can increase fly pressure and hygiene challenges inside livestock housing. Cow brushes help remove dirt, dust, loose hair, and external parasites from the coat, supporting cleaner animals and improved skin condition.

Regular grooming can also help reduce contamination build-up across the herd.

Calmer cows and quieter sheds:

Cows with access to grooming brushes often show less restlessness and fewer stress-related behaviours. This can create a calmer overall shed environment and reduce unnecessary contact with gates, barriers, and housing equipment.

For farms managing large housed groups, calmer cow flow can also improve movement around feeding and milking areas.

Better comfort supports performance:

Comfortable cows generally feed, rest, and recover more effectively. Many farms report improvements in overall herd condition, milk performance, and general cow behaviour when welfare-focused housing features are introduced.

While brushes are only one part of a wider housing strategy, they can support more consistent day-to-day comfort inside the shed.

Easy integration into existing sheds:

Modern cow brushes are designed to fit easily into existing dairy systems. Many activate automatically on contact, operate with low energy use, and move safely out of the way when not in use.

This allows farms to improve welfare provision without creating disruption to normal routines or machinery access.


Best practice for positioning cow brushes

Placement is important to encourage regular use.

Cow brushes are typically most effective when installed in:

  • high-traffic areas,
  • routes between feeding and resting zones,
  • areas near parlours or robotic milking systems,
  • locations with good airflow and visibility.

Brushes should remain easily accessible without obstructing cow movement or creating congestion points.

Regular cleaning and inspection are also important to maintain hygiene and ensure reliable operation during busy periods.


Supporting summer welfare in dairy housing

Cow brushes work best as part of a wider approach to heat stress management.

During warmer weather, farms should also focus on:

  • maintaining effective shed ventilation,
  • improving airflow,
  • reducing humidity build-up,
  • ensuring access to clean water,
  • avoiding overcrowding,
  • managing bedding condition,
  • controlling fly pressure.

Together, these measures help create a more comfortable and stable environment for housed cattle.

They also support broader welfare objectives and farm assurance requirements, including Red Tractor standards and herd health management goals.


A practical addition to welfare-focused dairy housing

Cow brushes provide a simple and practical way to support cow welfare inside modern dairy sheds. By encouraging natural grooming behaviour, they help improve comfort, cleanliness, and environmental enrichment while supporting calmer behaviour during warmer conditions.

For farms focused on welfare, housing standards, and herd performance, cow brushes can form part of a more comfortable and better-managed dairy environment.
