Parallel parlor configuration provides for a shorter walking distance than a herringbone for the operator and fits more cows because of the 90 degree angle facing away from the pit. A wider area is needed when installing a parallel to compensate for the entire length of the cow. Small gates or chute fronts are used to keep the cattle in position. The parlor is configured so that stalls are not able to use until the very farthest is taken to ensure all stalls are utilized each round. Typically, in a parallel parlor you will find a rapid exit stall front with dual return lanes. Disadvantages include reduced visibility of front quarters due to rear leg access to the udder which can also complicate the unit attachment and udder sanitation process. Parallel parlor design is widely customizable and the number of stalls can be chosen based on herd size, numbers of milkings per day & herdsman preference.
