Gutzbusta® USA Review 2026: The Best Slow Feed Hay Nets for Horses?

What Is Gutzbusta®?

Gutzbusta® is an equine nutrition accessories brand that specializes in slow feed hay nets for horses, ponies, and livestock. Originally developed in Australia — where it became the country's most widely used slow feed net brand — Gutzbusta has been supplying US customers through gutzbusta.com and has built a loyal following among American horse owners who prioritize evidence-based equine feeding practices.

The brand's full product range includes:

• Individual slow feed hay nets in knotless and knotted construction, from Extra Small to Extra Large
• Round bale nets in 3x4, 4x4, 5x4, and 6x4 foot sizes (knotless and knotted)
• A Large Square Bale net for full square bale feeding
• The Hay Stay hanging system
• A Salt Lick Net for controlled mineral feeding
• Heavy duty carabiner clips for secure hanging

Every product is built around a single measurable outcome: a GutzBusta® hay net reduces hay wastage by up to 46%.

The Science Behind Slow Feeding

Before evaluating the products themselves, it's worth understanding why slow feeding matters — because the benefits go well beyond saving money on hay.

Stomach acid and ulcers. A horse's stomach produces acid continuously, regardless of whether the horse is eating. When a horse goes more than 2–3 hours without forage, acid accumulates in the lower stomach and attacks the stomach lining. Studies suggest that up to 90% of performance horses and 60% of pleasure horses have some degree of gastric ulceration. Slow feed nets eliminate the long gaps between eating, keeping a steady stream of forage moving through the stomach and neutralizing acid with each chew.

Insulin management. For horses with laminitis, insulin resistance (IR), or Cushing's disease, bolus feeding — giving a large amount of hay all at once — creates an insulin spike that can trigger laminitic episodes. Continuous slow access to hay maintains a far flatter insulin curve. This is why Gutzbusta nets are particularly recommended for metabolic horses: with hay available at all times through a restrictive mesh, there is no large bolus, no spike.

Mental health and boredom. A stabled horse with nothing to eat for hours will find something to do — and that something is usually cribbing, weaving, wood chewing, or other stable vices that develop into ingrained habits. A horse working through a hay net is an occupied horse.

Hay savings. Loose hay on the ground is walked on, urinated on, and scattered. A GutzBusta net keeps hay contained and forces the horse to work for each bite, dramatically extending how long a given quantity of hay lasts. The brand's documented figure of up to 46% waste reduction translates directly to a lower feed bill.

Product Range: What Gutzbusta® Offers

Individual Hay Nets — Knotless

The knotless range is Gutzbusta's premium line. Made from soft, cross-woven polypropylene mesh with no hard knots and no metal joints, knotless nets are gentler on horses' lips and gums than traditional rope nets. The 5mm PP construction is high-strength without being abrasive.

The wide-mouth opening on every knotless net makes filling significantly easier than competitive products — you can throw in hay flakes without wrestling the net open. All knotless nets are safe to use on the ground with unshod horses.

• Extra Small Knotless — Holds 1 flake / ~2kg. Ideal for stalls, horse trailers, and miniature horses or donkeys
• Small Knotless — Holds 2–3 flakes. Good travel net and backup stall feeder
• Medium Knotless — 38" x 34", holds 10–12kg / 22–26.5lbs. The most popular individual size; ideal for overnight feeding in stalls and paddocks
• Large Knotless — Holds a full half-bale. Good for horses that need feeding for longer stretches between fills
• Extra Large Knotless — Maximum capacity individual net; minimizes filling frequency

Individual Hay Nets — Knotted

The knotted range uses traditional rope construction with visible knots at each intersection. This makes them significantly more durable and resistant to damage from rough feeders, horses that paw at their net, or outdoor feeding conditions. The trade-off is that rope knots are harder against the horse's mouth than soft mesh.

• Extra Small Knotted — Durable option for small feeders in rough conditions
• Medium Knotted — Holds 10–12kg. Wide opening for easy filling; extremely popular for horses that are hard on equipment
• Large Knotted — Full half-bale capacity with heavy-duty rope construction
• Extra Large Knotted — Maximum individual knotted capacity; ideal for outdoor paddock feeding

Round Bale Nets

Round bale nets are where Gutzbusta really separates itself from the competition. The ability to enclose an entire round bale in a slow feed net transforms round bale feeding from an all-you-can-eat buffet into a controlled, extended grazing experience.

Knotless round bale nets:

• 3x4 Round Bale Knotless
• 4x4 Round Bale Knotless — The most popular round bale size. A 4x4 bale fed through a 1¾" net can last 3–4 horses between 7 and 15 days
• 5x4 Round Bale Knotless
• 6x4 Round Bale Knotless — For large herds or the biggest bales

Knotted round bale nets:

• 4x4 Round Bale Knotted — Rope construction for maximum durability in outdoor environments
• 5x4 Round Bale Knotted

Specialty Products

Large Square Bale Net — Designed to fit a full square bale. Fill once, hang it up, and your horse feeds slowly from it for days. The side opening makes cutting bale strings and filling the net straightforward — no wrestling required.

Hay Stay Hanging Knotless Net — A hanging system that keeps the net at a natural head height off the ground. This is particularly relevant for horses prone to neck strain from extended ground-level feeding, or in situations where preventing hoof contact with the net is a priority.

Salt Lick Net — Applies the slow-feeding principle to mineral blocks. Rather than allowing unrestricted licking that can lead to overconsumption, the Salt Lick Net slows access and extends the life of your salt block significantly.

Heavy Duty Carabiner Clip — A quality carabiner with safety closure designed specifically for hanging hay nets. Simple but frequently undervalued — a poor clip is how nets end up on the ground.

Mesh Size Guide: Choosing the Right Opening

This is the most important decision when buying a Gutzbusta net. The mesh size determines how quickly your horse can extract hay — smaller holes mean slower eating but also require the horse to work harder.

For first-time users: Start with 1¾" (Moderate). This is the most commonly used size and provides strong hay-saving benefits without being so restrictive that your horse becomes frustrated or refuses to use the net.

For metabolic horses (laminitis, IR, Cushing's): The 1¼" (Decelerator) or 1" (Balanced) mesh controls intake more strictly and flattens the insulin curve more effectively.

Introducing the net gradually. Horses that have never used a slow feed net should be introduced to it during daytime, with familiar hay, and initially with a larger mesh size. Monitor the horse's body condition and ensure they are eating adequately before leaving them on the net overnight.

Who Is Gutzbusta® For?

Owners of horses prone to ulcers or colic. This is the most compelling use case. If your horse has a history of gastric ulcers, or if your vet has recommended reducing bolus feeding, a Gutzbusta net is one of the most practical and evidence-supported interventions available.

Owners of laminitic, IR, or Cushing's horses. The combination of continuous low-level hay access (no insulin spikes) and controlled mesh size (limits rapid ingestion) makes Gutzbusta nets essential equipment for managing metabolic horses.

Stabled horses with behavioral issues. Cribbing, weaving, and wood chewing are often directly related to extended periods with no forage. Gutzbusta nets give stabled horses something constructive to do during the hours when hay would otherwise run out.

Round bale feeders trying to reduce waste. If you're currently feeding round bales loose in a field, the amount of hay being wasted to trampling and contamination is likely significant. A Gutzbusta round bale net is one of the highest-ROI purchases available in equine management.

Owners of miniature horses, ponies, and donkeys. These animals are often prone to obesity and laminitis and benefit enormously from restricted, slow hay access. The Extra Small knotless net is particularly popular for miniature donkeys and mini horses.

Pros and Cons

Pros

Documented waste reduction of up to 46%. This is a genuine, measurable outcome — not a vague marketing claim. The savings in hay alone often pay for the nets within weeks of use.

15+ years of product development. The mesh sizing system, net dimensions, and construction choices reflect extensive real-world feedback from horse owners. The product has been continuously refined over a decade and a half.

Knotless construction is genuinely superior for horse welfare. No metal joints, no hard knots against the mouth — the knotless range represents a meaningful improvement over older rope net designs for horses with mouth sensitivity.

Wide size range. From Extra Small individual nets for miniature horses in horse trailers, to 6x4 round bale nets for large herds — Gutzbusta has a product for every feeding situation.

Excellent for metabolic horses. Few equine products are as specifically useful for laminitic and IR horses as a quality slow feed net. The combination of continuous hay access (no insulin spike) and mesh-restricted intake rate is a cornerstone of metabolic horse management.

Strong customer reviews. Across multiple US retail channels, Gutzbusta products consistently earn praise for quality, durability, and ease of filling.

Cons

Transition period required. Horses that have never used a slow feed net need time to adapt. Some horses are initially reluctant, particularly with smaller mesh sizes. This is manageable but requires patience and gradual introduction.

Shod horses need additional management. Direct contact between metal shoes and the net is not recommended. Shod horses need the net hung higher or placed inside a hay ring — an extra step that some owners find inconvenient.

Round bale nets require some physical effort to set up. Getting a net over a full round bale is easier with two people. It's a one-time setup per bale, but worth planning for.

Gutzbusta® vs. The Competition

vs. Hay Chix: Hay Chix is the most widely known US slow feed net brand. Gutzbusta's knotless range is generally considered softer and gentler on horses' mouths, and the mesh sizing system is more granular (5 mesh sizes vs. fewer options from most competitors). Hay Chix has stronger domestic brand recognition; Gutzbusta has a stronger product development history.

vs. Derby Originals: Derby Originals offers budget-friendly hay nets. Gutzbusta's construction quality and mesh sizing precision are meaningfully better, reflected in the price differential. For horses where slow feeding is a medical necessity (ulcers, laminitis), the investment in a quality net is justified.

vs. Standard rope hay nets (generic): Traditional rope hay nets with 3–4" openings don't slow feeding at all — they're hay containment, not slow feeding. Gutzbusta's range delivers actual intake reduction that standard nets simply cannot.

Final Verdict: Is Gutzbusta® Worth It in 2026?

For horse owners who understand the relationship between feeding patterns and equine health — yes, unequivocally.

A Gutzbusta® hay net is one of the few equine products where the return on investment is both measurable and fast. Up to 46% hay waste reduction means most nets pay for themselves within a few weeks of use. The health benefits — fewer ulcers, better insulin management, reduced boredom behaviors — are harder to quantify but widely documented and broadly accepted in equine veterinary practice.

The knotless range is particularly impressive: the soft mesh construction, the wide-mouth filling design, and the 15 years of refinement behind the product are evident in use. For laminitic and IR horses specifically, a quality slow feed net with the right mesh size is not an optional accessory — it is a core part of responsible management.

Rating: 4.8 / 5

Frequently Asked Questions

Does slow feeding with a hay net actually reduce ulcers? Yes. Horses produce stomach acid continuously. Eliminating the long gaps between feeding — which Gutzbusta nets do by extending how long hay lasts — reduces the time acid spends pooling in the stomach with no hay to buffer it. This is the primary mechanism behind slow feeding's well-documented association with lower ulcer incidence.

How long does it take a horse to adapt to a Gutzbusta® net? Most horses adapt within 1–2 weeks. Start with a larger mesh size (1¾" Moderate), use familiar palatable hay, and introduce the net during daytime where you can monitor the horse. Some horses adapt within days; others take longer depending on temperament and prior feeding history.

What mesh size is best for a laminitic horse? Most equine nutritionists recommend 1¼" (Decelerator) as the starting point for laminitic horses. This provides meaningful intake restriction without being so small that the horse becomes frustrated. The Medium Knotless or Large Knotless in 1¼" mesh is a common recommendation.

Can I use a Gutzbusta® round bale net in a field with multiple horses? Yes. Round bale nets are regularly used with multiple horses. Monitor for any horses that are being pushed away from the bale by dominant herd members — if competition is an issue, providing a second net or feeding station is recommended.

How long does a round bale last with a Gutzbusta® net? Gutzbusta's documented figure is that a 4x4 round bale fed through a 1¾" net can last 3–4 horses between 7 and 15 days depending on the season and hay palatability. In summer with low-sugar hay, the same bale has been reported to last nearly 3 months for the same number of horses.

Are knotless nets as durable as knotted nets? Knotless nets are made from high-strength 5mm PP polypropylene — they are strong and long-lasting for typical use. Knotted nets are more durable under rough conditions (hard-chewing horses, outdoor environments, abrasive surfaces). Both are built for long-term use.

What accessories do I need with a Gutzbusta® hay net? At minimum, a quality clip for hanging. The Heavy Duty Carabiner Clip is specifically designed for this purpose with a safety closure. For horses prone to neck strain, the Hay Stay Hanging Net provides an off-ground hanging solution.
