AMENIA — Amid unanimous favorable reports from the herd, Coon Brothers dairy farm in Amenia held an open barn on Sunday, Dec. 1, inviting contractors and friends to visit the cows and see their new automatic milking system that has brought robotics to the modern dairy industry.
Coon Brothers has used GEA equipment for milking over the years, so co-owners Peter and Amos Coon indicated that GEA Dairy Robot equipment was chosen to automate their operation, requiring a long period of construction.
The preceding year had been given to renovating the barns in preparation for installation of the robotic equipment that began in the spring and continued into July. Six robotic milking stations have been installed and all are now kept busy throughout the day.

Each cow decides for herself when to go in for milking, the decision prompted by discomfort. Observation showed that the cows placidly await their turns without disagreements or jostling for position.
“The difference is the cow’s comfort,” Amos explained. “Now they are getting milked when they want to,” he added.
The farm has a population of 600 animals with 350 milk cows, including Guernseys and Holsteins, divided between two barns, Peter Coon said.
“The system is better for the cows and it will save labor,” said Coon. “and the cows seem to like it.”
The computerized system monitors each cow, recognizing individuals by a computer chip attached to the cow’s collar. During each milking session, the cow’s milk production and quality of the milk are instantly measured and tested, with any problems detected and dealt with.
The system isolates and collects data from each quarter of the cow’s udder.
Cows residing in the milking barn are there all the time, Amos Coon said. “The new system has changed how we do everything.”
In the barn the cows munch on molasses flavored silage but get a treat in the milking stall in the form of custom grain.
Milk output is measured in pounds, not gallons. One cow can produce 20 pounds of milk in a single milking session, Amos explained. They go for milking more than once a day; some cows may give as much as 140 pounds of milk in a single day. Genetics contribute to a top-producing cow, Amos said.
A cow that has recently calved gives more milk, with increased production lasting 50-200 days. A newborn calf will only suckle for 12 hours before being shifted to manual feeding of bovine colostrum which is separated from the cow’s milk production by the robotic system.
In the event of a power outage, a generator keeps the systems going.
A large 6,000 gallon milk collection tank holds the milk until a tanker truck takes it away.
Robotic milking is not new to the area. Freund’s Farm in East Canaan has also installed automated milking with good results.
Max Amsterdam reaches out to pet a red panda at the Trevor-Lovejoy Zoo on Millbrook School’s campus on Wednesday, Dec. 17. Amsterdam is a senior at Millbrook School and serves as the zoo’s head student curator.
Stahl said the zoo has been engaged in a long-range master planning process for several years as part of preparing for its next Association of Zoos and Aquariums accreditation review in 2027. “We knew we had to make a plan and look toward the future,” Stahl said. “We had to think about what more we could be doing for the animals, for students and for the community.”
Construction is nearing completion on a new animal holding barn, the first step toward housing off-exhibit animals. Funded by philanthropist Barbara Tober — whom Stahl described as the project’s “catalyst” — the facility is required under AZA accreditation standards. The holding barn will serve as a first stop for new animals required to quarantine before entering an exhibit. It will also safely house animals when enclosures are being repaired or when they need rehabilitation.
The new animal hospital, which zoo staff are referring to as an animal wellness center, is poised to be four times larger than the existing space. Stahl said the team is looking forward to dramatically expanding the zoo’s ability to treat animals on campus, eliminating the need to transport them off-site for procedures like X-rays or ultrasounds.

Stahl said a primary goal of the master plan and the animal wellness center is to “bring the outside in.” The public will be allowed to watch certain procedures and operations to learn more about the veterinary work that goes on behind the scenes.
In addition to the zoo’s around-the-clock staff, rotating veterinarians visit the zoo each week to check on the animals and perform routine procedures. The current space is limited, and zoo staff are eager to have an expanded footprint.
“Right now we’re very limited space-wise,” Stahl said. “This new facility will let us have more space, more vets and more learning happening.”
Max Amsterdam has lived at the Millbrook School as a boarding student for four years and has held a working role at the zoo throughout that time. Today, in his senior year, he serves as the zoo’s head student curator — a coveted leadership role that requires a formal application and selection process.
When Amsterdam first applied to Millbrook School, the zoo was not front-of-mind. Although he wanted to become a veterinarian as a young child, the desire dissipated until he set foot in the Trevor-Lovejoy Zoo as a freshman.
“I watched a senior perform a biopsy on a red wolf that had passed away from a uterine tumor,” Amsterdam said. “I didn’t even know that students could do that. I realized right then how incredible this place was and the zoo became my thing.”
Over his four years at Millbrook, Amsterdam has assisted veterinarians, shadowed medical procedures, conducted necropsies and even traveled with staff to national AZA conferences. “As you grow, you gain a relationship with the staff and vets, and when they know you can handle it, they let you do more,” he said.
With graduation on the horizon and plans to study biology at Bucknell, Amsterdam admits he’s a little jealous of the future students that will benefit from the new zoo facilities.
At the end of the day, he is grateful for the hands-on experience he has received in his leadership roles at the zoo. Millbrook School is the only high school in the country with an AZA-accredited zoo on its campus.
“I’m jealous, but I’m also so grateful that the zoo got that donation because it’s needed,” Amsterdam smiled. “We deserve it, too. It’s a lot of hard work by the staff and students — it’s 200% effort seven days a week, and not many people see that.”
