Bedding Recovery from Manure

Recycling bedding from separated manure solids can cut purchased bedding needs, but it only works if the material stays clean enough for cows to lie on. The details matter for udder health.

What recovered bedding is

Recovered bedding is the solid fraction taken out of manure by a separator or similar equipment, then dried or composted before it goes back under cows. Some farms use sand recovery systems for sand-bedded barns instead.

The idea is simple. The execution is not, because bedding is the surface where cows spend much of their day and where bacteria meet teat ends.

Separation equipment can include screw presses and sloped screens, and the choice affects how wet the solids are. Drier solids are easier to process, while wetter solids need more drying time or more careful composting.

Why farms consider it

Bedding supply and cost can be a constant worry. Recovery lets a farm use an on-farm resource and lowers the volume of manure to store and haul.

It is not a free solution. Equipment, power, labor and management time are real costs, and the herd's udder health must be watched closely.

• Lower purchased bedding demand
• Less solid material in storage
• Reuse of an on-farm resource
• Added equipment, labor and monitoring needs

Common methods

Separated solids can be dried in a rotating drum or composted in a bunker or windrow, and the finished material is then screened and stored. Sand systems use settling lanes and washing to reclaim sand from flushed manure.

Each system has different needs for space, heat, airflow and handling. Visit farms that use a system and talk about what they would change before you commit.

Space is often the limit. A composting or storage area must drain properly and keep runoff out of surface water, so check local rules on siting before you plan the layout.

Keeping it clean enough

Bedding that is warm, damp and rich in nutrients grows bacteria quickly. How well the material is processed, stored and managed in the stall decides whether it helps or hurts.

Work with your vet and a mastitis advisor to set up monitoring. Many herds track bulk tank quality, clinical case rates and teat end cleanliness before and after a change.

• Process and store material according to equipment guidance
• Keep finished bedding covered and out of rain
• Add fresh bedding to stalls often and remove wet spots
• Groom stalls at every milking or as often as your plan calls for
• Track new infections and clinical cases from the start

What to ask before investing

Ask for a plan that covers the entire flow, not only the machine. Where do solids go, who handles them, how is finished material stored, and what happens when the system is down?

Talk with your milk buyer or herd veterinarian about any program requirements that touch bedding, since certification and buyer programs can have their own rules.

• What is the total labor and power requirement?
• What is my backup bedding if the system stops?
• How will I know if udder health slips?
• Does local regulation treat recovered material differently?

Choosing the right bedding for your plan

Bedding type drives almost everything downstream. Sand, sawdust, straw, paper-based material and recycled solids each behave differently in the system, and each has its own effect on cow comfort and udder health.

Before you commit to recovery, think about the bedding your cows lie on today. If udder health is already a struggle, fix that first. A stable herd gives you a clear baseline to compare against.

Ask your vet how the herd currently performs on new infection rates and teat end condition, and keep those numbers handy so you can tell whether a change helps or hurts. If the supply of finished material is not enough for the whole herd, use it on selected groups and keep the rest on your usual bedding rather than stretching it thin.

• Record your starting udder health measures
• Make changes one pen at a time
• Have a written plan for what triggers a rollback
• Keep purchased bedding available during the trial

Common mistakes

The most common mistakes are rushing the start, using material that is not fully processed, and putting it in stalls that are not groomed. Another is switching the whole barn at once instead of testing on a pen first.

Start small, watch closely, and keep your vet in the loop. If new infections rise, stop and review the process rather than waiting it out.
