OptiDuo Robotic Feed Refresher vs Aramis II
Two robotic barn machines, one verified table. Every figure below is sourced and dated; vendor claims are labelled and kept apart from independent results.
DeLaval's robotic feed pusher-and-remixer — unlike plain pushers, a twin-spiralled rotating auger remixes the ration while repositioning it at the feed fence, keeping roughage strands intact so refused compacted feed stays appetising. Adaptive Drive adjusts speed and track to feed type and quantity; runs around the clock, up to 10 trips a day. Direct competitor to the Lely Juno.
Best for: Robotic-milking or free-stall dairy herds that want feed pushed AND remixed 24/7 — especially where compressed, sorted-through TMR is depressing intake at the fence.Rail-guided all-in-one feeding robot from Tyrolean specialist Hetwin — weighs, cuts, mixes, doses and pushes feed around the clock from an overhead rail, with two horizontal mixing augers producing a homogeneous ration from batches as small as 50 kg. Aimed at medium herds of roughly 50–150 animals; sold and serviced in Switzerland via Harvestore.
Best for: Medium dairy and fattening barns (≈50–150 animals) wanting fully automatic group-specific fresh feeding without a mixer wagon — overhead rail keeps the feed alley clear.| OptiDuo Robotic Feed Refresher Verified 2026-07-16 | Aramis II Verified 2026-07-16 | |
