Advancements in Robotic Milking Systems Transforming Dairy Farming

Robotic milking systems have undergone significant advancements over the past two decades, revolutionizing the dairy farming industry. The University of Wisconsin-Division of Extension's Professor Doug Reinemann highlights the key developments that have shaped the user experience and expanded the adoption of these automated systems.

One notable change is the growth in the size of robotic installations. While early installations featured two- and four-box-style robots, recent years have seen farms with as many as 64 robots, including impressive installations like the 36 Lely Astronaut robots at Homestead Dairy in Indiana and the upcoming 62 DeLaval VMS robots at Longs Peak Dairy Galeton in Colorado, making it the largest robotic milking facility in the United States.

The introduction of robotic rotary systems, such as the GEA DairyProQ system, has provided a new approach to managing cows in groups. These systems utilize one robotic arm per stall and enable operators to monitor the milking process through computer screens. The transition to automatic milking requires careful consideration of management systems, as it often involves a shift from managing groups to managing individual cows.

Additionally, other system styles, like the DeLaval Automatic Milking Rotary, offer prepping robots, attaching robots, and post-dipping robots. Although this particular system is yet to be installed in the United States, it provides flexibility as both a batch and voluntary system.

The choice of traffic patterns in barns with robotic systems plays a crucial role. Free-flow designs, commonly used with Lely robotic milkers, eliminate gates between resting, feeding, and milking areas, allowing cows to be milked based on individual selection. Guided-flow systems, often paired with DeLaval robotic systems, incorporate selection gates to regulate cow movement. Research suggests that both traffic patterns are equally successful with smaller herds, but as capacities increase, differences may emerge.

The continuous evolution of robotic milking systems enhances efficiency and management on dairy farms. Future considerations include flexible barn designs and customized pen configurations to accommodate different herd sizes, traffic patterns, and stages of lactation. As the industry embraces these advancements, dairy farming is poised to experience increased productivity and improved cow health.
