In the high-stakes world of egg production, choosing the right housing system is the most critical decision a farmer can make. While the industry continues to innovate with complex vertical systems, the Gaiola de camadas tipo A (also known as the A-frame cage) remains a global favorite for its simplicity, ventilation, and cost-effectiveness.
As we move through 2026, the demand for high-quality, durable equipment is at an all-time high. Leading the charge in modernizing this classic design is Grande pastor, a global giant in livestock equipment that has taken the traditional Type A cage and infused it with high-tech automation and superior materials.
The Type A layer cage is named for its triangular, ladder-like configuration. Unlike vertical H-type systems, the tiers in an A-frame system are offset. This design offers several natural advantages:
Superior Airflow: The staggered design allows for natural air circulation, which is vital in tropical climates or houses without expensive tunnel ventilation.
Easy Inspection: Because the tiers don’t overlap completely, it is much easier for farm staff to visually inspect every bird in the flock.
Investimento inicial mais baixo: For farmers looking to scale up from floor-rearing to caged systems, the Type A cage offers a lower entry cost while still providing the benefits of high-density housing.
Gaiola para postura Big Herdsman Tipo A
While many manufacturers produce A-frame cages, Grande pastor has re-engineered the Gaiola de camadas tipo A to meet the rigorous standards of modern commercial farming.
The biggest enemy of any poultry cage is corrosion from ammonia and humidity. Big Herdsman utilizes a hot-dip galvanization process for all cage mesh and frames. With a zinc coating of up to 275g/m², these cages are built to resist rust for 15 to 20 years, ensuring your investment stands the test of time.
One of the highlights of the Big Herdsman system is the integration of automated egg collection belts.
Manuseamento suave: The system is designed to minimize the slope of the cage floor just enough so eggs roll safely onto the belt without gaining too much speed.
Redução da quebra: By automating the collection process, Big Herdsman reduces human handling, bringing the egg breakage rate down to less than 0.5%.
Big Herdsman’s Type A systems aren’t just “cages”—they are automated hubs. They feature:
Trolley Feeders: A precise feeding car that travels along the cage rows, distributing even amounts of feed to every bird, reducing waste and ensuring uniform nutrition.
Nipple Drinking Systems: High-quality stainless steel nipple drinkers provide 360-degree access to clean water, keeping the litter dry and the birds hydrated.
Traditional A-frame cages often relied on “pit” systems for manure. However, Big Herdsman offers a modernized version featuring Manure Deflector Boards ou Automated Scraper Systems.
By directing waste into a central collection area, these additions significantly reduce ammonia levels inside the poultry house. This creates a healthier respiratory environment for the layers, which directly translates to a higher laying rate and better shell quality.
Even the classic Type A cage gets a digital upgrade with Big Herdsman. Their Rede de Fazenda Inteligente IoT platform allows farmers to monitor the environment around their cages in real-time. Whether it’s tracking water consumption per row or monitoring the temperature at the top tier vs. the bottom tier, Big Herdsman puts the power of data into the palm of your hand via a smartphone app.
With a global footprint spanning over 95 countries, Big Herdsman is more than a supplier; they are a partner in project success. For B2B buyers, they offer “Turnkey” services, meaning they help with everything from the initial house layout and civil engineering advice to the final installation and commissioning of the cages.
