The tour highlighted the double-10 herringbone parlor
, a two-row free stall barn excellent for ventilation, biosecurity, and traffic flow and the sand/manure separator and manure storage structures.
Currently, a D-8 to D-12 parallel or herringbone parlor
is considered a single-person parlor, a D-20 to D-25 a two-person parlor, and so on.
Figure 19-17 shows the inside of the D-6 herringbone parlor that was built as part of this low-cost dairy complex.
It is a T -style facility, with a D-6 herringbone parlor and a two-row freestall barn.
Herringbone parlors get their name from the angle at which cows are positioned with respect to the pit wall.
In both parallel and herringbone parlors cows are loaded, milked, and released in batches.
Milking Procedures and Routines Used in Parallel and Herringbone Parlors
In parallel and herringbone parlors, there are three predominant milking routines: group, sequential, and territorial.
In large parallel and herringbone parlors, cows per stall per hour were 5.
Three predominant milking routines are used in parallel and herringbone parlors (sequential, grouping, and territorial).
Since cows can exit when they are finished (they do not need to wait until the last cow in the group is finished), the number of cows milked per stall per hour is higher than with parallel or herringbone parlors.
The expected throughput of parallel and herringbone parlors is normally between four and five turns (times filled per hour), depending on the operation's circumstances.
