Recommendations for Cow Stall Bedding Management on Dairy Farms After Flood Disasters

Recently, frequent heavy rainfall has occurred across various regions, leading to flood disasters in many areas. The damage inflicted by floods on dairy farm stall bedding is significant. Contamination from silt, debris, and pathogenic microorganisms seriously threatens cow health, particularly causing a sharp increase in the risks of mastitis and hoof diseases. Addressing post-disaster stall bedding and considering the use of rubber mats is indeed a wise decision.

The following details the handling procedures and recommendations regarding the use of rubber stall mats:

I. Emergency Handling Steps for Cow Stall Bedding After a Flood Disaster

Safety Assessment and Silt Removal:

Safety First: Ensure the site is safe. Check structural stability （stall supports, ground for potential collapse）. Confirm no risk of electrical leakage in power-off areas before entry.

Thorough Contaminant Removal: Remove all flood-soaked bedding material （sand, rice hulls, sawdust, manure, etc.）, silt, and debris （branches, plastic, etc.）. This is the most fundamental and crucial step and must be carried out thoroughly.

High-Pressure Washing and Surface Cleaning:

Use a high-pressure washer （with sufficient pressure） to thoroughly rinse all structures, including the stall surface, brisket board, and supports. The goal is to wash away all residual mud, organic matter, and most attached microorganisms. Pay special attention to corners, crevices, and other areas prone to harboring dirt.

Drainage and Drying:

Unblock Drains: Ensure drainage ditches in and around the stall area are unobstructed to prevent water re-accumulation. Inspect and repair damaged drainage facilities.

Promote Drying: Utilize natural ventilation and sunlight as much as possible to dry the area. If conditions allow, use large fans �� for forced ventilation, or even consider industrial drying equipment to speed up the process. A damp environment is a breeding ground for pathogens; drying is crucial.

Deep Disinfection:

Select Appropriate Disinfectant: Use broad-spectrum, efficient disinfectants that are safe for cows （e.g., peracetic acid, glutaraldehyde-quaternary ammonium compound blends, chlorine dioxide, quicklime, etc.）. Rotate between different types of disinfectants to avoid resistance development.

Thorough Disinfection: After surfaces are relatively dry （excess moisture dilutes disinfectants）, saturate and spray all stall surfaces, floors, and surrounding walls thoroughly and without missing any spots, using spraying equipment （e.g., mist cannons, backpack sprayers） according to the recommended concentration. Pay special attention to cracks and bottom areas.

Multiple Disinfections: Typically, 2-3 rounds of disinfection are necessary, with intervals between each （based on disinfectant requirements and drying conditions）, to ensure the elimination of stubborn pathogens （e.g., spores）.

Environment and Bedding Assessment:

Check Stall Foundation: Assess whether the ground or supporting structure beneath the stalls has softened, collapsed, or been damaged due to flooding. Repair or rebuild if damaged.

Evaluate Original Bedding :

Sand Bedding: Sand often becomes severely compacted and contaminated after floods, making it difficult to clean and disinfect thoroughly. Complete removal and replacement with new sand is strongly recommended. The cost and effectiveness of cleaning old sand are often inferior to replacement.

Organic Bedding （Rice hulls, sawdust, recycled manure solids, etc.）: This bedding is generally unusable after being soaked by floodwater and must be completely removed and disposed of safely （e.g., composting, while taking care to prevent pathogen spread）. Replace with new, dry, clean bedding material.

Rubber Mats/Mattresses: If already installed, these become the primary focus for cleaning and disinfection （see the rubber section below）.

Restore Bedding or Install rubber mat bed:

Only after completing all the above cleaning and disinfection steps and ensuring the environment is completely dry, should new bedding be laid or rubber mats be installed.

If continuing to use bedding （e.g., sand, organic bedding）, ensure the source is clean, dry, and uncontaminated. More frequent maintenance （turning, adding, replacing） may be needed initially.

II. Recommendations Regarding the Use of Rubber Stall Mats Post-Disaster

The period after a flood disaster can be an opportunity to consider converting traditional bedding stalls to rubber mats, as rubber mats offer significant advantages for post-disaster recovery and long-term hygiene management:

Advantages （Particularly prominent in the post-disaster context）

Excellent Ease of Cleaning and Disinfection Effectiveness:

Smooth, seamless surfaces （high-quality mats） allow high-pressure washers to easily and thoroughly rinse away all dirt, silt, and most pathogens, leaving no dead spots.

Disinfectants can evenly cover the surface and act effectively, are not easily absorbed, and leave no residual dead spots. Disinfection effectiveness is far superior to porous bedding materials （e.g., sand, organic bedding） that easily harbor dirt. This is key for post-disaster pathogen control and mastitis risk reduction.

Rapid Drying:

Rubber does not absorb water. After rinsing and disinfection, coupled with ventilation, it dries extremely quickly. This significantly shortens the waiting time before stalls can be reused and reduces opportunities for pathogens to thrive in damp environments.

Elimination of Bedding Contamination and Replacement Hassles:

Avoids the significant cost and trouble associated with traditional bedding （especially sand） that becomes contaminated by floodwater, is difficult to clean, and must be entirely replaced.

Long-term, it also saves the substantial labor and costs associated with daily bedding procurement, transport, spreading, and waste bedding disposal.

Reduced Pathogen Harborage:

Compared to porous, loose bedding materials, the dense, smooth rubber surface makes it more difficult for bacteria, fungi, and other pathogens to survive and hide long-term, contributing to better overall stall hygiene.

Improved Cow Comfort and Health （Long-term）:

High-quality rubber mats provide stable, cushioned support, promoting cow rest, rumination, and rising/lying movements, reducing joint injuries, and improving comfort and milk yield.

Better hygiene directly reduces the incidence of mastitis and hoof diseases.
