Sistemas de gaiolas para galinhas poedeiras: tipos, especificações e faixas de preço

“Layer cage” is not one product. It covers at least three structurally different formats, and each one carries a different price basis, footprint, and labor requirement. Below, published dimensions are separated from category-average figures.

What “Layer Cage” Actually Covers

Three formats get sold under this label, and mixing them up is where most quote requests go sideways.
H-type automatic battery cage — a stacked, multi-tier system with mechanized feeding, drinking, egg collection, manure removal, and climate control built in. This is the format most commercial operations scaling past a few thousand birds end up specifying, because labor cost per bird drops sharply once collection and manure handling stop requiring hands.
Type A cage — a lower-automation battery frame, typically manual or semi-manual in feeding and collection. It costs less to buy but more to staff, and it’s the format smaller or budget-constrained operations tend to start with before retrofitting to H-type later.
Enriched (welfare) cage equipment — built to meet welfare-standard requirements common in EU and export-oriented markets. It sits in a different regulatory conversation than the two formats above, and buyers targeting welfare-certified export channels should treat it as its own sizing exercise rather than a variant of the H-type.
A fourth term shows up in the same search results and causes real confusion: the layer brooder cage, used for raising chicks before they reach laying age, not for housing hens in production. If your search intent is chick-rearing rather than egg production, that’s a separate equipment category with its own spec sheet — not covered further here.

Layer Cage Formats at a Glance

H-Type Automatic Layer Battery Cage: Full Dimensional Specifications
This is the format with published parameters, so it’s the one you can plan a house around without waiting on a custom drawing.

One figure this table doesn’t answer, because it isn’t itemized on the current spec sheet: birds per tier or per cage. That number varies with cage width configuration and isn’t standardized the way the frame dimensions are, so treat it as a required question for your supplier conversation rather than something you can back into from the table above.

The taller end of that height range — the 4+4 tier build at up to 6,580 mm total structure height — needs a house with real roof clearance to work. A converted barn or a house built for a 3-tier layout won’t take a 4+4 retrofit without structural changes, which is worth confirming before you spec automation level rather than after.

Where Type A Still Makes Sense

Type A trades automation for lower upfront cost. Feeding and collection stay manual or semi-manual, which raises the labor line on your operating budget in exchange for a lower equipment line. Operations that plan to phase into automation — start with Type A, retrofit to H-type once volume justifies the labor savings — use this as a deliberate staging strategy rather than a permanent choice. If that’s your plan, confirm retrofit compatibility with your supplier before the first purchase; not every Type A frame accepts an H-type conversion later.

How to Estimate Floor Area Before You Request a Quote

1. Confirm target flock size at peak production, not starting flock size — cage systems are sized for the number you’ll actually be running at full capacity.
2. Pick a tier configuration against your house’s roof clearance. A 3-tier system needs roughly 2.33–2.86 m of clearance at the low end of the published range; a 4+4 tier build needs up to 6.58 m structural height and 7.11 m roof height. If you’re retrofitting an existing structure, this step usually decides the configuration before automation level does.
3. Rough out footprint using the published spacing: 1,200 mm column spacing and 1,570 mm trough spacing per row, plus a 2,055 mm service aisle for every aisle you plan to run equipment through.
4. Match automation level to your labor budget, not the other way around — a fully automated system only pays back its higher per-bird cost if the labor it displaces was going to be a real line item.
5. Request exact bird-per-tier capacity from the supplier directly. This is the one number the published spec sheet doesn’t carry, and it’s the number your final floor-area math actually depends on.

What Layer Cage Systems Cost

Mugong pricing is project-specific and quote-based. The figures below are published market-reference ranges — useful for self-qualifying a budget, not a fixed price from any one supplier.

Two numbers get conflated constantly in supplier conversations, and it’s worth separating them explicitly: the per-bird equipment figure above covers cage hardware alone. Once housing, ventilation, and site preparation enter the picture, the relevant number is a per-project installed cost, and it moves independently of the per-bird equipment range — a project with an existing usable structure and one built from bare ground can land at very different totals even with identical cage equipment.

Perguntas frequentes

 What’s the difference between an H-type and a Type A layer cage?

H-type systems automate feeding, drinking, egg collection, manure removal, and climate control. Type A cages are manual to semi-manual, which lowers equipment cost but raises the labor requirement per bird.

 How many birds fit in an H-type cage system?

It depends on tier configuration (3 through 4+4 tier) and cage width, and exact bird-per-tier capacity isn’t itemized in the published spec sheet. Confirm this figure directly with your supplier before finalizing floor-area planning.

 Is the $15–25 per bird figure the full project cost?

No. That range covers equipment only. Housing, ventilation, and site preparation are priced separately and move independently of the per-bird equipment figure.

Do enriched cage systems cost more than H-type battery cages?

Detailed pricing for enriched/welfare cage equipment isn’t published in the current catalog. Given the added compliance requirements against enriched-cage welfare standards, budget for a dedicated quote rather than assuming parity with standard H-type pricing.

Can I start with Type A and retrofit to H-type later?

Some operations do exactly this to phase capital spend, but not every Type A frame accepts an H-type conversion. Confirm retrofit compatibility with your supplier at the time of the original purchase, not after.
