This fan features a one-piece molded FRP (fiberglass-reinforced plastic) construction that is rust-proof and resistant to ammonia corrosion, offering a service life far exceeding that of standard metal fans. Its conical outlet design delivers an airflow of 44,000 m³/h, while the direct-drive motor eliminates the need for belts, ensuring maintenance-free operation. Ideal for negative-pressure ventilation in livestock facilities such as poultry and pig houses, it can lower temperatures by 5–10°C when paired with cooling pads. Combining corrosion resistance, high airflow, and durability, it is becoming the preferred choice for upgrading ventilation systems in large-scale livestock farms.

Steel-structure livestock farms utilize hot-dip galvanized portal rigid frames with spans up to 30 meters; they offer a 60% shorter construction period and an anti-corrosion lifespan exceeding 20 years. Featuring prefabricated construction, a design life of 25 years, and an overall cost of 300–450 RMB/m², this method has become the mainstream choice for new farms, accounting for 78% of the market in 2024.

This 50-inch ventilation fan features six SUS 430 stainless steel blades and is specifically designed for livestock farming. The blades are resistant to ammonia corrosion, delivering an airflow of 38,000 m³/h with low noise and energy efficiency. It effectively exhausts moisture and harmful gases from the facility, reducing livestock stress and extending equipment lifespan. Suitable for poultry houses, pig barns, and dairy farms, it helps large-scale operations cut costs and boost efficiency, setting a new standard for ventilation equipment quality.

The harvesting of traditional broiler chickens has long relied on manual catching, resulting in high injury rates, low efficiency, and significant costs. Chain-based automated harvesting systems enable birds to be removed without being physically handled by moving the floor mesh as a single unit; this keeps injury rates below 1%, reduces catching costs to approximately 0.06 yuan per bird, and achieves a removal speed of up to 2,400 birds per hour per line. Numerous domestic equipment manufacturers have now launched mature solutions, and the technology is transitioning from concept to large-scale application, becoming a standard feature in modern broiler farming and driving the industry toward greater intelligence and efficiency.

PVC fence is a commonly used plastic fence panel in modern pig houses. It is mainly used in sow farrowing beds, piglet incubators, nursery pens and fattening pens.

Its advantages are: durable and rust-free (galvanized pipes will rot in three to five years in the humid acid-alkali environment of the pig house, while PVC can be used for 30 years), smooth surface and easy to clean (clean with a high-pressure water gun, and germs are not easy to breed), does not hurt pigs (no burrs and sharp corners, will not scratch pigs), maintenance-free (no need to paint, no maintenance), and easy to install (light and easy to carry, just snap it in place).

Although it is a little more expensive than galvanized pipes at the time of purchase, it saves money in the long term because it does not need to be repaired and replaced every year. Building a new pig farm or renovating an old farm are both worthy of consideration.

There has long been a debate regarding the choice of materials—square versus round tubing—for sow anti-jump pens. Visits to farms and a review of mechanical engineering data reveal that square tubing offers distinct advantages in impact resistance, structural stability, and service life, making it the preferred choice for large-scale pig farms.

Impact and Bending Resistance: Square Tubing Clearly Superior

Research indicates that square tubing absorbs energy more effectively than round tubing; it better cushions the force of impacts from sows, thereby reducing the risk of damage to the pen structure. From a materials mechanics perspective, for a given cross-sectional area, square tubing boasts a moment of inertia against bending approximately 70% higher than that of round tubing, resulting in superior resistance to deformation. Empirical data shows that square tubing undergoes significantly less deformation under lateral impact and exhibits better recovery capabilities.

Installation, Connections, and Service Life: Square Tubing Offers Greater Stability and Durability

Square tubing provides a larger flat contact surface, allowing for stronger welds; the shear resistance at connection points is markedly superior to the line contact found with round tubing. Over time, connections in round-tubing structures are prone to developing significant gaps due to wear, whereas square-tubing structures remain more stable. Pens made of square tubing have an average lifespan of approximately five years—two years longer than those made of round tubing—resulting in lower long-term overall costs.

In modern pig production, the farrowing crate is a critical piece of equipment specifically designed for sows giving birth and nursing piglets; it typically comprises a sow restraint crate, a piglet warming box, slatted flooring, and feed troughs.

Core Functions of the Farrowing Crate
The design of the farrowing crate centers on protecting both the sow and her piglets. The restraint crate confines the sow to a specific area, preventing her from crushing piglets when turning or lying down—a measure that can reduce piglet mortality due to crushing by more than 50%. Slatted flooring allows manure and urine to drain promptly into the pit below, keeping the pen surface dry and effectively reducing the incidence of piglet diarrhea. The warming box provides a localized, warm environment of 33–35°C for newborn piglets, compensating for the temperature difference, as the ambient temperature around the sow is typically only around 20°C.

Choosing Chicken Cage Mesh: 4 Materials Compared
Four common wire mesh materials—electro-welded, hot-dip galvanized, post-hot-dip galvanized, and aluminium-zinc alloy—vary in corrosion resistance and lifespan. Electro-welded is cheapest but rusts quickly (8-10 years). Hot-dip galvanized offers reliable 15-20 year service. Aluminium-zinc alloy provides 5-10× better corrosion resistance, lasts 20+ years, and saves long-term costs. Experts recommend it for modern large-scale farms. Always verify coating specifications with suppliers.

The 8×9×13 cm feeder trough (top width × bottom width × height) is widely used in layer operations. Its trapezoidal cross‑section matches birds' pecking and scratching: the 8 cm height deters soiling, while the sloped 9‑to‑13 cm walls help deflect feed back into the trough. The size suits both pullets and layers, eliminating the need for stage‑specific changes. Available in PVC or galvanised steel, it resists corrosion and cleans easily. The dimensions fit most cage brackets and work with manual or automatic feeders, simplifying installation and replacement. Routine care—filling only one‑third full, weekly clean‑outs, and prompt repair of damage—keeps waste low. This proven, economical specification remains a favourite among farmers worldwide.

In the layer farming industry, choosing between an open house and a closed (environmentally controlled) house is a core decision that shapes your investment scale, management approach, and final returns. Both systems have their supporters, but it’s not about which is “better”—it’s a strategic choice based on local climate, available capital, and management capability.
