Manure Collection & Alley Systems

The Importance of Manure Collection

Dairy cows produce significant amounts of manure daily—keeping barns clean requires efficient collection systems. Good manure management improves cow comfort, reduces hoof problems, maintains milk quality, and captures nutrients for beneficial use.

Collection Systems

Mechanical Scrapers

• Alley scrapers: Cable or chain-driven blades that push manure to collection points
• Automatic systems: Timer-controlled for regular cleaning cycles
• Manual scrapers: Tractor-mounted for periodic cleaning

Flush Systems

• Water-based systems that flush manure to collection
• Higher water use but less mechanical maintenance
• Require adequate water supply and recycling
• Work well with sand-laden manure

Vacuum Systems

Vacuum trucks or systems that suction liquid manure from collection points.

Robotic Scrapers

Autonomous scrapers that navigate barns continuously, keeping alleys clean without fixed infrastructure.

Components and Features

Scraper Systems

• Scraper blades (rubber or steel)
• Drive units (hydraulic, electric, cable)
• Control systems and timers
• Cross-alleys and corner scrapers

Collection Points

• Cross-channels and pits
• Reception tanks
• Separation equipment
• Transfer to storage

Selection Factors

• Barn layout and alley configuration
• Herd size and manure volume
• Bedding type (sand, organic, mattresses)
• Climate and seasonal considerations
• Labor availability
• Integration with storage system

Cost Considerations

Simple alley scraper systems start at $15,000-30,000. Comprehensive barn scraper installations run $50,000-150,000 depending on barn size and complexity. Robotic scrapers cost $15,000-25,000 per unit. Flush systems require significant infrastructure investment. Operating costs include electricity, maintenance, and periodic blade replacement.
