Milking Parlor Layout Basics

A milking parlor is a workplace for people and a stop on the daily route for cows. A good layout makes both easier, and a poor one costs you labor, milk quality and cow comfort every single day.

Key points

Design the cow path first, then fit the equipment into it.
Size the holding area for the group you milk, and avoid crowding.
Protect milkers with a pit and work area that fit the people using them.
Plan drainage, utilities and room for expansion early.
Visit working parlors and ask operators what they would change.

Start with cow flow, not equipment

Most layout problems begin with the cow path, not the milking units. Cows are herd animals that prefer to move forward, see where they are going and keep their group around them. Before you pick a parlor style, trace the full loop: from the pen, through the return lane or holding area, into the parlor, through exit, and back to feed and water.

Look for sharp turns, dead ends, steps, slick floors and shadows. Cows balk at sudden changes in light and footing, and a balky cow slows every cow behind her. Time spent drawing the path on paper is cheaper than moving concrete later.

Holding area basics

The holding area is where cows wait, and it sets the tone for the whole milking. It should be sized for the group you actually milk at one time, with enough room that cows are not crushed against each other, yet not so large that cows are standing a long time.

A crowd gate that moves cows gently is useful, but it should never be used to push hard. Ask your parlor designer and your extension specialist for the stocking guidance that fits your cow size and herd.

Walk the holding area at the start and end of milking. If cows are still standing in large numbers long after the last group went in, or if cows are slipping near the gate, something in the design or handling needs attention.

The operator work area

The milker works in the same spot for hours, so the design should protect the back, shoulders and wrists. Pit depth, reach distance to the udder, and the position of the unit hose all matter. A pit that is wrong for the height of the people who work in it will show up as sore backs and sloppy routines.

Plan where supplies live, where the teat dip is mixed and stored, and where a milker can step out to deal with a problem cow without stopping the line. Good traffic through the pit prevents bumping and tangled hoses.

Exit, return lane and sorting

Cows leaving the parlor should have a clear, wide, straight exit and an easy return to feed. Slow exits back up the whole parlor. If the return lane crosses an area where cows are already eating or resting, you will see jostling and wasted time.

Think about where you will sort cows for breeding, treatment or health checks. A sort gate on the return lane saves a lot of chasing, and it can be a calm place to catch a cow that needs the veterinarian.

Staff should be able to see every cow leaving the parlor. Make sure there is a place to stop and look at a cow's udder or gait without blocking the lane.

Cleanliness, water and utilities

Parlors get washed down daily, so surfaces should drain, resist wear and be easy to scrub. Plan where manure and wash water will go so cows are not walking through standing water with every milking.

Remember the less glamorous parts: hot water supply, electrical service, vacuum pump location, milk house access and room for future expansion. Follow manufacturer instructions and local code for electrical and plumbing work, and keep stray voltage in mind when planning grounding.

Common mistakes to avoid

The usual errors are an undersized holding area, a pit that does not fit the people working it, tight turns on exit, and designing for today's herd with no room to grow. Another is copying a neighbor's parlor without checking whether his cows, labor and schedule match yours.

Visit several working parlors, and ask the operators what they would change. Talk to your milk buyer or field representative about any requirements for the milking area.

Planning for growth and for change

A parlor will likely outlast several herd changes, so leave room. Think about where an extra set of stalls could go, how the holding area could be enlarged, and whether the milk house and vacuum pump can handle more load.

Also think about the people. A layout that works for a crew of experienced milkers should also work for a new hire on a bad morning, with clear sight lines, safe footing and an easy way to ask for help.

When to get help: Before you commit to a layout, review plans with an experienced parlor designer and your local extension dairy specialist, and ask your milk buyer or inspector about any requirements for the milking area and milk house.
