A recent study confirms that Green Source Automation’s RotaryMATE outperforms the human labor it is intended to replace.
Dairy research at universities and other institutions across the US and around the world have consistently shown that Somatic Cell Counts decrease when proper pre-milking and post-milking processes are applied to the cows. In particular, using predip and postdip has a marked impact on the reduction of mastitis and improvement in SCC.
Other studies have shown that improperly executing the pre-milking and post-milking processes will not help and, in some cases, even have a negative impact on herd health and SCC in the milk.
VDS Farms is a well-run operation that consistently has some of the lowest SCC in the country. They wanted to tighten their operation further, improve the consistency of their pre- and post-milking processes, and benefit their bottom line by replacing human labor with robotic automation.
To achieve this aim, VDS installed two RotaryMATE systems, the RotaryMATE EXPS for the pre-milking process, and the RotaryMATE EXPD for the post-dip application.
The challenge in front of Green Source was to replace these labor positions without losing any of the effectiveness that VDS has achieved in keeping SCCs in the sub-90,000 range.
After both systems had been installed and running, Green Source and VDS set out to prove the effectiveness of the RotaryMATE EXPS at cleaning and sanitizing the teats when compared to the human labor process previously in place.
Research has proven that clean, sanitized teats reduces the environmental bacteria that can cause mastitis. While the human labor process at VDS was clearly effective, Green Source sought to prove that the RotaryMATE would perform even better. To do this, a side-by-side sampling and testing was conducted.
In all the tests that were done, the same pen of animals was tested each time in order to control for the variable of where the cows were prior to entering the rotary to be processed. This allowed for a true apples-to-apples comparison of the effectiveness of the cleaning process by human labor and by the RotaryMATE EXPS.
To test and measure the cleanliness, GSA and VDS Farms used Adenosine TriPhosphate (“ATP”) testing equipment, an industry standard practice from multiple industries including the food industry.
"ATP bioluminescence tests…are used in the food industry in order to keep food manufacturing clean. The tests are a reliable, simple, and rapid way to monitor surface contamination in the food industry and to detect contaminants in beverages or drinking water. For surface contamination testing…a pen-like device is swabbed over the tested area, then inserted into the handheld reader called relative light unit or RLU. The results are displayed within seconds and can indicate if the sample is clean or unclean… It is estimated that 80 percent of the food production facilities in North America and more that 80 percent in Europe are using this ATP testing technology for sanitation monitoring and validation of whether the processing equipment is clean enough to be used for food production."

Since the cows in the VDS rotary parlor enter head first, the front teats are farther away from the human labor and more difficult to reach. Given this variable, the ATP test was divided into two sets: one test for the easier-to-reach rear teats, and one for the harder-to-reach front teats. The surface samples were taken from the sidewalls and openings of the teats.
Equal numbers of samples were taken of the teats processed by human labor and the teats processed by the RotaryMATE EXPS. The results were then averaged for all animals for both respective test groups (front teats and rear teats).
After the test results were averaged, the RotaryMATE EXPS significantly outperformed manual human labor in both tests.
The rear teats, which are easiest for human labor to reach, showed a 27% improvement using the RotaryMATE EXPS. The front teats improved by 49% using the RotaryMATE EXPS.
Delivering cleaner teats prior to the milking cups being attached is a significant contributor to lowering the SCC in the milk produced.
VDS Farms has installed both the RotaryMATE EXPS and RotaryMATE EXPD robots. They have successfully eliminated two labor positions on their rotary, and they have also improved the cleanliness of the teats prior to the milking cups being attached. Both robots have played a significant role in maintaining the Somatic Cell Count at VDS at 86,000, while also allowing for the benefits of consistent labor via robotic automation.
Camille Vanpee, Director of VDS Farms, said, “We could not be happier with the high-speed robotic automation solutions provided by Green Source. We are thrilled to be able to reap the benefit of reduced labor costs, while also maintaining the high quality milk VDS Farms is known for. The RotaryMATE has met and exceeded our expectations.”
