The parallel parlor has become the dominant parlor configuration in North American dairy, displacing older herringbone and flat barn designs. The 90-degree cow positioning—perpendicular to the operator pit—enables rapid attachment, efficient indexing, and excellent visibility of the udder from the rear.
Cows enter in groups corresponding to the parlor size (double-16, double-24, etc.), filling stalls on both sides of the central operator pit. Rapid-exit designs open all headlocks simultaneously, clearing each side quickly for the next group. Some designs feature individual stall exits for sequential cow release.
Operator ergonomics excel in parallel configurations. The pit depth positions milkers at comfortable working height for the uddeer. Attachment occurs from directly behind the cow, with clear sightlines to all four quarters. The consistent position reduces repetitive strain compared to angled approaches.
Throughput depends on parlor size, equipment quality, cow preparation, and operator skill. Well-managed double-24 parallels achieve 200+ cows per hour with two operators. Larger parallels (double-40 and above) are common on operations milking 1,000+ cows.
Parallel parlors integrate effectively with modern technology—RFID identification, automatic takeoffs, milk meters, sort gates, and in-parlor feeding systems. This technological compatibility has reinforced parallel dominance as dairies invest in precision management.

Buying Considerations
Important factors to consider when evaluating What Is a Parallel Milking Parlor?:
- Parlor Configuration Angle: 45° offers balance of throughput and comfort, 50-60° angles provide better cow positioning and operator access but require more space and higher investment
- Stall Count and Size: Typically 2x8, 2x10, 2x12, or larger configurations. Each additional stall adds $8,000-$12,000 to installation cost but increases throughput capacity
- Automation Level: Basic manual systems start at $35,000 per stall, semi-automated with take-offs add $15,000-$20,000, fully automated systems reach $60,000+ per stall
- Integration Capabilities: Ensure compatibility with existing herd management software, feed systems, and farm management platforms. Integration costs range $25,000-$50,000
- Service and Support Network: Local dealer support critical for 24/7 operations. Evaluate response times, parts availability, and technician training programs in your region
Evaluation Questions
Key questions to consider when evaluating What Is a Parallel Milking Parlor?:
- What parlor size matches our current and planned herd size?
- What automation features should we include for future-proofing?
- How does cow flow and holding area design support throughput?
- What is the dealer's service and parts availability?
- How do total milking hours compare to alternatives like robots?
Common Mistakes to Avoid
Avoid these common mistakes when implementing What Is a Parallel Milking Parlor?:
- Undersizing holding area capacity
