OptiDuo Robotic Feed Refresher vs Butler Gold Pro
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.Free-driving feed pusher and concentrate dispenser from Austrian feeding specialist Wasserbauer — a 700 kg, 24 V robot that navigates by 5 mm floor magnets set roughly every 2 m, makes up to 99 passes per day and, unlike a plain pusher, uses a special auger to throw feed loosely back to the trough without pressing it. Its 120-litre container (or 2 × 60 l for two components) doses concentrate, minerals or liquids onto the base feed along the way; the drive-over charging station manages batteries automatically.
Best for: Dairy barns wanting more than a pushing drum: fresh, loosened feed plus in-pass concentrate/mineral dosing from one robot, with typical energy use under 4 kWh/day for a 100-cow barn at 14 passes.| OptiDuo Robotic Feed Refresher Verified 2026-07-16 | Butler Gold Pro Verified 2026-07-17 | |
