Dairy Shed Design for Pakistan’s Climate: Space, Ventilation and Floors

A good shed pays for itself through more milk, fewer mastitis and lameness cases, and easier work. In Pakistan the main design challenge is heat: the shed must give shade and airflow in summer while offering some protection in winter.

Orientation and roof

• In hot regions, orient the long axis of the shed roughly east–west so the sun crosses over the roof rather than shining deep inside.
• Build the roof high — a high roof keeps hot air further from the animals and improves airflow.
• Use light-coloured or insulated roofing; bare metal sheets become very hot underneath.
• Extend the roof edges (overhangs) to keep rain and low sun off the animals.

Ventilation

• Keep the long sides open (or with removable side curtains for winter) so wind can pass through.
• Fans over resting and feeding areas, combined with sprinklers, are very effective in summer.
• Avoid low, closed sheds — they trap heat, moisture and ammonia, which increase disease.

Space

Crowding reduces lying time, feed intake and milk, and increases fighting. Allow enough resting space for every animal to lie down at the same time, enough feeding space that all can eat together, and an open loafing area if land allows. Buffaloes generally need a little more space than cows.

Floors and drainage

• Floors should be rough enough not to slip but not so rough that they damage hooves.
• Slope floors gently toward drains so urine and water run off.
• Provide dry, soft bedding (straw, sand or rubber mats) in resting areas.
• Remove dung at least daily.

Feeding and water

• Feed troughs raised slightly off the floor, smooth and easy to clean.
• Water troughs in more than one place, close to feeding and resting areas, with clean water at all times.

Separate areas

Plan for a calving pen, a calf area, an isolation pen for sick or new animals, and a clean milking area. Store feed away from dung and moisture.

Manure management

A planned dung pit or composting area away from the shed and water sources reduces flies — which spread mastitis, LSD and other diseases — and turns waste into valuable fertiliser.
