Robotic Milking Hygiene: Special Cleaning Requirements for AMS

How Robotic Milking Changes the Hygiene Equation

Automatic Milking Systems (AMS) have fundamentally changed the milking model in dairy operations that adopt them. Cows milk voluntarily, on self-directed schedules, with no fixed milking times. This means the hygiene interventions that were scheduled around parlor milking — teat dipping after the milking session, cluster cleaning between animals — now have to be automated and integrated into the robotic unit's operating cycle.

Understanding what changes in hygiene requirements when moving from a conventional parlor to an AMS is essential for selecting the right products and protocols.

Teat Preparation in the Robotic Unit

In a conventional parlor, the operator prepares and checks each teat before attachment. In a robotic system, teat preparation is automated by the robot arm, which brushes, rinses, and dries teats in a pre-attachment cleaning cycle built into the unit's software.

The teat preparation brush and nozzle system must be clean between cows. Many AMS platforms include automated cleaning of the preparation arm between animals. Products used for this must be compatible with the robotic system's materials — brushes, synthetic teat cups, and sensor equipment — and must not leave residues that interfere with the teat end detection and attachment systems.

Post-Milking Teat Dipping in AMS: Automatic Dipping Units

After milking in an AMS, post-milking teat dip must be applied to each cow before she leaves the robot. Automatic teat dipping nozzles or cups built into the robot apply the dip product automatically. This requires products specifically formulated for automatic application equipment:

• Vilnus LA DP RBT: post-milking teat dip formulated for robotic automatic dipping unit application
• Vilnus F100 AC RBT: film-forming post-milking teat dip for robotic application where extended teat end protection between voluntary milkings is required

The formulation must be compatible with the dipping nozzle geometry, dip cup material, and dosing hardware of the specific AMS platform installed.

Circuit Cleaning in AMS

The milk circuit of a robotic milking unit is cleaned in automated cleaning cycles during the periods when the robot is not milking — typically at preset intervals or overnight. The cleaning cycle runs an alkaline wash and, less frequently, an acid descaling cycle through the circuit.

Capuluna CLEAN RBT is AgroLyne's alkaline cleaning product formulated for robotic milking circuit cleaning. Key formulation requirements for AMS circuit cleaning products:

• Low-foam: robotic circuits use lower water volumes than conventional CIP; excessive foam causes problems with pumps and sensors
• Concentrated format for dosing into the AMS cleaning system's chemical reservoir
• Material compatibility with the synthetic and rubber components of the robotic unit

Implications for Buyers and Distributors

Farms operating robotic milking systems need a separate, compatible product set. Conventional teat dip and milking system cleaning products may not be suitable for AMS use. Buyers sourcing hygiene products for robotic dairy operations should specify AMS-compatible formulations and verify compatibility with the specific robot platform (major brands include Lely, DeLaval, GEA, and Fullwood Packo).
