Introduction to VMS™ Batch Milking

For more than 20 years, DeLaval VMS™ units have been used on dairy farms across New Zealand and beyond. Some producers utilising robotic milking facilities have experienced a range of advantages, including reduced labour requirements, more flexibility on and off the farm, valuable cow data, higher production levels, improved milk quality and better cow health.

The key benefit of robotic milking lies in the autonomy it provides to cows, allowing them to decide when to begin the milking process. This choice can be facilitated through a guided cow traffic system or within a free-traffic barn, where cows have the freedom to move about at their discretion. In these setups, dairy cows can express their genetic potential around the clock, meaning they can be milked as often as they like and as permitted by their owner.

What is VMS Batch Milking?

VMS™ Batch Milking is a new way of milking larger groups of cows robotically, and it is gaining traction with currently 13 installations in 10 countries.

In a typical VMS barn, cows are housed in different groups according to their needs, potential and the configuration of the barn. They eat, drink, milk and rest all under the same roof—and on their own schedules over a 24-hour period. Interestingly, farms accustomed to conventional parlour or rotary milking can still reap similar benefits with VMS Batch Milking. Here, the milking process is automated but the familiar routines of milking a herd in a parlour remain under the schedule of the owner.

How does it work?

VMS Batch Milking requires herds to be divided into groups. A person then brings those groups one at a time to the milking center, like parlour milking. One popular barn layout with batch milking involves two rows of multiple VMS units. The facility arrangement mimics a parallel parlour, featuring a central holding area between the robots. Upon milking completion, all cows exit out of the robot to the right and follow the exit lane around the perimeter of the milking center until they are met by a selection gate. This gate can guide them to a herd health sort area, the holding pen or back to their original pen—with no labour involved.

“VMS Batch Milking allows farmers to milk their cows in groups according to lactation stage, like they would in their conventional milking operation,” said Stephanie Dillon, advisory specialist at DeLaval. “Transitioning to batch milking can be seamless for producers since many of the same routines are the same as conventional milking and the requirements for training staff are minimal.”

VMS Batch Milking offers the additional advantage of enabling farms to maintain their total mixed ration (TMR) feeding regimen, avoiding the need to shift to a partial mixed ration (PMR), as the pellets fed in the robot are minimal and used as an incentive or a distraction rather than for nutrition. This approach allows the farm to extract greater value from the home-grown forages they produce. Much like feeding practices, various routines typical in conventional milking operations can remain unchanged in VMS Batch Milking. These include tasks such as cleaning stalls while cows are milking, sorting cows to a designated area for herd management and adhering to set milking times. This continuity helps make the transition to robotics easier for farm staff, as the learning curve is notably less steep in this style of robotic milking.
