Cows should not have to walk farther than 15-20 stall widths to a crossover. Provide additional crossovers for group sizes larger than 60-80 stalls. That way, a "boss" cow cannot monopolize a waterer or block a crossover. There should be at least two waterer locations (Figure 2) and two crossovers per pen. They must be wide enough that cows don't block the crossover, especially when there is a waterer located in the crossover. Space them so they allow cows freedom to access feed and lying areas without receiving too much interference from other cows. CrossoversĬrossovers allow cows to travel from one alley to another.

The group size should match multiples of the parlour size, if possible, so that the parlour is full or almost full when the last cow in the group is milked. It may not be practical to divide a small herd into many groups. Group size Consider the number of groups and the size of the pens when deciding on the layout. Waterer on the outside wall at an end crossover. They too can operate in an alley width of 2.4-3 m (8-10 ft). Robotic feeding may become more popular in the future with the introduction of robotic automatic feed mixing and delivery systems. When belt-feeders or rail feeders are used to automatically deliver feed to the cows, the feed alley width can be reduced to 2.4-3 m (8-10 ft). Protect the doors on the outside with bollards (vertical pipe filled with concrete). Be sure to make drive-through doors at least as wide as the drive-through to avoid damage. It should be at least 6 m (20 ft) wide to prevent equipment from driving on feed and should be 6.7 m (22 ft) if the TMR mixer is parked in the drive-through. The drive-through feed alley must be wide enough to accommodate the drive-through feed equipment. When it is not possible to provide the desirable alley widths, extra crossovers may be added to reduce the cow traffic congestion.
#Churchtown dairy barn design free
In a head-to-head arrangement, where cows must exit the free stall into the feed alley, an alley width of 3.6 m (12 ft) is acceptable, but 4.3 m (14 ft) is better to allow for the extra cow movement. In a tail-to-tail barn where the cows lunge into the feed alley, 3.6 m (12 ft) is an acceptable width. The cow-feed alley is the alley between the row of free stalls and the feed manger. Double stall platforms should be 18 ft long. The minimum alley width should be 2.4 m (8 ft), but if a skid steer is used to bed the stalls and has to turn 90° to the stall, then the alley width should be 3 m (10 ft). The alley width will depend on the type of equipment used to clean the alleys and bed the stalls. Cow traffic alleys Cow traffic alleys are the cow walkways between the rows of free stalls in tail-to-tail barns, and between the outside row of stalls and the wall in head-to-head barns. If the platform length is less than 5.5 m (18 ft), cows may be reluctant to lay in stalls directly across from each other.
Double stalls The platform length of a double row of free stalls in a head-to-head arrangement should be 5.5 m (18 ft) (Figure 1) to allow the cow to lunge forward without interfering with the cow in the stall directly across. Single stall The platform length for a single row of free stalls in a tail-to-tail arrangement should be 3 m (10 ft) long to the outside wall to allow for lunge room but can be 2.7 m (9 ft) long on the row next to the feed alley, as they can lunge into the alley space. Stalls Free-stall widths for Holstein cows should be 122 cm (48 in.), 132 cm (52 in.) and 137 cm (54 in.) for first lactation, milking and dry cows, respectively. Component designĭecide on the individual components first, then determine how they will fit together best to form the complete plan. This is where all the free-stall barn components come together to develop a plan that is functional, flexible, expandable and cost-effective. The housing layout or floor plan of a dairy barn is the most important document in the design process.
