New DeLaval P500 Parallel Parlor Milking System

After a period of previewing the system at North American tradeshows, DeLaval announced the official launch of the DeLaval Parlor milking system P500 – the next evolution of parallel parlors. Its unique design represents a new approach to moving cows calmly, quickly and efficiently through the milking process. It is the dairy industry’s only parallel parlor with three cow-flow control options and no sequence gates in the floor.

“The DeLaval Parlor P500 has been designed to do more on a smaller footprint, making it an ideal choice for both news builds and retrofits,” Gavin Strang, DeLaval Market Development Manager, Capital Equipment, said.

Highland Dairy of Glade Spring, Va., is a third-generation dairy farm milking 550 cows. When owner Rena Johnson spoke to her DeLaval dealer, Tri-City Dairy Equipment, about securing the sustainable, profitable growth of her family’s farm, she chose a DeLaval Parlor P500. As the new system’s first global reference farm, Highland Dairy started milking cows in its double-16 P500 in January 2019. Johnson is satisfied with the parlor’s better throughput, greater milk production and improved comfort for cows and employees.



“Before, we were using the parlor about 19 hours a day milking a modified 2x,” Johnson said of their old double-12 herringbone parlor. “Now, we’re milking (all cows) 3x, about 15 hours a day in the (new) parlor. It’s just so much better for us for throughput and efficiency, and we’ve gained an additional five pounds of milk. The cows really love the barn, and that tickles me to see them in there.”

The DeLaval P500 features all of the significant functionalities of the existing DeLaval parlor assortment, plus a newly developed synchronized milking process with these patented technologies:

  • DeLaval SynchroArc™ is more than an open-bottom neck rail with no obstructions. Its design promotes free-cow flow for optimum throughput, offers better indexing of mixed herds, and accommodates a 30 percent smaller footprint.* Ceiling heights can be as low as 96 inches.
  • DeLaval SynchroSweep™ features independently controlled, suspended, non-overlapping sequence gates, which also lift up during milking to minimize stress on cows and components. This design and process creates a quieter environment that can speed up cow-exit cycle times by 56 percent.*
  • DeLaval SynchroControl™ puts the operation of the milking system at the fingertips of the dairy producer. This feature makes it possible to configure multiple indexing management styles, contributing to its safe, comfortable and efficient operation.



  • DeLaval InService™ All-Inclusive for DeLaval Parlor P500 is a customer service program designed to enhance the reliability and performance of the milking system. ISAI provides service, consumables, advisory and everything in between on a contract basis so the customer knows his or her costs up front. DeLaval InService™ All-Inclusive provides farmers with time to focus on the business of dairy farming with the peace of mind that the system is running at peak performance.

The Next Evolution of Parallel Parlors

The P500 signifies a new approach in parallel parlors for DeLaval. In North America, this new milking technology will supersede the company’s previous parallel parlor models (Champion™, Cascade™ and Endurance™). More information can be found here

“The DeLaval P500 simplifies our parallel parlor offering while continuing to deliver the quality, reliability and longevity our milking systems are known for,” Strang said. “It has the potential to increase dairy producers’ profitability, reduce their costs and help them be more efficient with labor.”

  1. Milking machines do cause mastitis !!!

    I have attached some items regarding our product relative to Staph aureus. The first is a study published in the Journal of Dairy Science documenting a switch back study of our product compared to a conventional one. The results demonstrated a very significant result relative to preventing new staph aureus infections. I also attached a short summary of that study relative to that result.

    This study was a one year duration switch back study proving that our product virtually eliminates new Staph infections which are the most difficult type to deal with on dairies. The university was at odds with us marketing our product from the outset and it is believed that a competitor funded it to discredit us however the data proved the product works. Cornell still wrote a summary down playing the results. It is interesting to consider the statistics of the cows in the study. Their “random” distribution resulted in all known prior Staph infected cows ending up “randomly” in the CoPulsation group at the start of the test. The statistics of this “random” event are on the order of the probability of getting struck by lightning – kind of leaves one to question the Cornell honesty and intent. Cornell refused to release the raw data from the study which I believe would have shown the trend towards reducing environmental mastitis.

    The third attachment is a longer term study on a small local dairy that uses data provided by Cornell QMPS. It again shows the effectiveness in preventing Staph and also shows the effectiveness in addressing other mastitis forms.

    The following is text from an email from Dr. Sybren Reitsma, an international dairy equipment consultant who resides in Ontario Canada:

    Years ago I came across CoPulsation when I read the published article in the Journal of Dairy Science (2000 J Dairy Sci 83:2004–2007). That article showed an astonishing difference between conventional pulsation and CoPulsation. CoPulsation was very effective in preventing Staph. aureus infections to spread. The first dairy farmer I recommended CoPulsation to had a 1500 cow herd with rampant Staph. aureus. The farmer had already culled over 1400 cows and could not afford to replace any more cows. Installation of CoPulsation prevented spread to cows freshening. Also CoPulsation improved milking so much that they went to three times a day milking while before one milking could barely be completed in 12 hours. The farmer told me it saved his farm by preventing bankruptcy.

    There is additional research information at that describes how and why our product prevents new Staph infections. Basically Staph aureus is non-motile which means it cannot move on its own, it must be transported. The method of transport into the udder is by the liner closing in an upward rolling motion that forcibly shoves the bacteria up the canal into the sinus. CoPulsation liner action prevents that. The research at this link describes that and other independent research done in the UK years ago proving that conventional milking machines cause this forcible shoving.

    The forcible shoving has been known in the industry for years and simply ignored and buried so that dairy farmers are not aware of what causes mastitis. It was again documented 2004 in a paper authored by Graeme Mein, Doug Reinemann and Norm Schurring.

    Let me know if you have any other questions.
