GESTAL 3G: Feeding System for Gestating Sows in Group Housing

The GESTAL 3G is a precision electronic sow feeder (ESF) designed for group-housed gestating sows, manufactured by Jyga Technologies. Each station manages up to 18 sows individually. When a sow enters the feeding station, her RFID ear tag is read instantly and she starts to receive meals at a concurrent rate up to her exact pre-programmed daily ration automatically. The station structure mimics a traditional gestation crate, which allows sows to self-train with no employee intervention required.

The GESTAL 3G differs from conventional ESF systems in three measurable ways. First, it requires minimal gilt training: on a typical 5,000 sow farm, traditional ESF systems require 1 to 3 full-time employees solely for gilt training. The GESTAL 3G minimizes this labor draw through its self-training design. Second, it uses a simplified mechanical design with no complex moving parts, reducing breakdown frequency and maintenance time. Third, it reduces feeding costs by up to 10% compared to traditional free-access stalls and shoulder stanchions, with some producers reporting up to 25% savings in individual feeding costs versus conventional ESF. Each smart feeding unit operates as a fully independent, 100% autonomous station, no serial connections mean a single unit failure never disrupts feeding for the rest of the herd.

Yes. The GESTAL 3G installs in both new construction and retrofit barns, adapting to any building type, size, and existing flooring (concrete, slatted, or mixed). Jyga Technologies provides full project management support for barn conversions, including pen layout planning, station-to-sow ratio calculations, and on-site installation guidance.

Each sow's feeding program is configured individually in the GESTAL software, VISION, based on her body condition score, parity, and stage of gestation. Her RFID ear tag triggers the release of her exact programmed ration every time she enters the station, automatically deducting any feed already delivered earlier that day. With the optional Opti unit, two separate feed lines are blended in real time to create a customized ration for each animal, eliminating the need to over-formulate a single diet for the entire group. This reduces excess nitrogen and phosphorus excretion, lowering both feed cost and the operation's environmental footprint. Daily feed intake data for every sow is automatically logged and accessible via handheld tablets and automated reports, flagging any animal that misses a feeding.

Feeding continues uninterrupted. Each GESTAL 3G station is a fully independent, no station is connected to another in series. A computer crash or network outage does not cascade across the system; every other station keeps feeding normally. Individual units are built to maintain feeding operations independently for a short period without the central computer. This standalone architecture was a deliberate engineering decision by Jyga Technologies to eliminate the single-point-of-failure risk that affects conventional ESF systems wired in series. All units are also certified IP66 and NEMA 4X, protecting electronics against water, dust, and corrosion.

Yes. The GESTAL 3G is designed to comply with group housing animal welfare regulations, including the Canadian Code of Practice for the Care and Handling of Pigs (group housing mandate effective 2024) and EU Council Directive 2008/120/EC. By physically enclosing each sow during feeding, the station eliminates competition and aggression at the feed point, the primary welfare risk in group housing environments. Every sow eats at her own pace and receives her individually programmed ration regardless of social hierarchy. Pen design flexibility within the GESTAL 3G system allows producers to further optimize space and sow flow for their specific facility layout.

Each GESTAL 3G station manages up to 18 sows. For optimized feeding traffic and minimal wait times, we recommend approximately 15 sows per station in most commercial barn configurations. The correct station-to-sow ratio for a specific operation depends on group size, pen layout, and daily feeding window. Jyga's technical team provides custom barn design support to calculate the optimal number of stations and pen configuration before installation.

The GESTAL 3G is manufactured by Jyga Technologies, a Canadian company founded in 1994 and recognized as the first company in the world to design and produce electronic feeding systems for pigs. Jyga's owners are active pork producers, operating a 2,200-sow farrow-to-finish farm where all products are tested under real commercial conditions before reaching customers. The company serves producers across North/South America, Europe and Asia, supported by a multilingual technical team providing both remote and on-site installation and service.

All GESTAL products, including the GESTAL 3G, carry IP66 and NEMA 4X certifications. IP66 certifies full dust-tight protection and resistance to high-pressure water jets, making the system safe for pressure washing between production groups. NEMA 4X certifies resistance to corrosion and severe weather conditions. Together, these two certifications confirm that the GESTAL 3G electronics and mechanics can withstand the demanding environment of a commercial gestation barn across years of continuous operation.

The GESTAL 3G automatically records individual feed intake data for every sow at every meal, every day. Additional feeding behavior reports are also generated. This data is accessible in real time via handheld tablets and compiled into automated daily reports through the VISION software. The system flags sows that have not visited their station or have consumed less than their programmed ration, enabling early detection of health issues, estrus, or lameness before clinical signs are visible. Body condition management, ration adjustments, and herd-wide feeding analytics are all managed from the tablet interface without requiring a desktop computer or office workstation.
