Rotary parlors

In rotary parlors, the cows are loaded one at a time onto the platform as it slowly rotates. The milker stands near the entry to the parlor and puts the cups on the cows as they move past. By the time the platform has completed almost a full rotation, another milker or a machine removes the cups and the cow steps backwards off the platform and then walks to its feed.

 Rotary cowsheds, as they are called in New Zealand, started in the 1980s but are expensive compared to Herringbone cowshed - the older New Zealand norm. To justify the costs herds have got bigger with 1 person milking 500-600 cows. A rotary is about 25% faster than a herringbone shed for the same number of cows.
