Helps to secure quality of colostrum. It comes with improved fly protection and is easy to use and clean. It provides a more gentle and safer handling of separated milk.

The Astronaut now also enables Eartag ID. The A5 Next provides entry-level identification for enhanced flexibility.

The important first touch. The healthier the udders, the better the milk. This is why the Astronaut is equipped with a unique brush cleaning system that is designed to remove encrusted dirt and manure around the teats and the underside of the udders, ultimately stimulating milk let-down. After cleaning the teats, the brushes are thoroughly disinfected to help minimise the risk of cross-contamination.

Free Cow Traffic
With free cow traffic, the cow decides when she eats, drinks, lies down and is milked. This improves her well being. By taking care of our cows and putting extra effort into cow comfort, we are able to extend lifetime milk production. Sufficient space in the barn will also give the cow the opportunity to display her natural behavior and improve her overall well being. Thanks to the I-flow concept cows feel comfortable. With the silent hybrid arm and improved teat detection system cow comfort is increased even more.
I-flow concept and hybrid arm
I-flow concept
The Astronaut's I-flow concept is designed with cow comfort in mind. Cows dislike obstacles, which is why the I-flow concept offers a straight route with unhindered entrance, leading cows to their milking turn with ease. The cows enter the milking unit naturally, with no need to navigate sharp corners. Also, the cow stays within the comfort of the herd. The simple, straight-line design in and out of the milking box minimises stress and makes milking a seamless part of their daily routine.
Hybrid arm
The hybrid arm combines fast, silent and accurate electrical-driven movements with the softness and the power of air for stress-free milking. The air protects the electrical system by balancing the heavy load of the arm and buffering cow kicks. The hybrid arm is silent, allowing cows to experience more rest during milking.

Milking solution

The process
Start-up support: every step of the way
Before
Before the Astronaut comes into operation, we help you prepare your farm for automatic milking. This includes discussions on cow health, feeding, daily routines, Free Cow Traffic, and Partial Mixed Ratio feeding. We also provide training on robot operation and the associated management system.
01
During
When the Astronaut is installed, the robot is extensively checked. Together we go through the new routines and group the cows. Once every detail is accurate, milking begins. During the initial milking, we provide intensive support.
02
After
Once everything is up and running the start-up period ends and we begin with the next step to further optimise your farm according to your preferences. Together we will define which services will support you best.
03
Milking
Producing high-quality milk requires time and care. It requires making choices that fit in with you and your goals. Our solutions for automatic milking help you make the right decisions to attain those goals.
