Modern pig house floor innovation: four materials to create a healthy breeding environment

Technological revolution under pig's trotters, new flooring improves breeding efficiency by 30%

In modern pig farming, scientific flooring systems have become key facilities to ensure the health of pigs and improve breeding efficiency. The four mainstream products of BMC composite flooring, cast iron flooring, triangular steel flooring and engineering plastic flooring have their own characteristics, which are promoting the transformation and upgrading of traditional pig farming models. Qingdao Puhui Agriculture and Animal Husbandry Technology Co., Ltd. provides a variety of flooring options

1. BMC composite flooring: a high-strength and long-life choice
BMC (bulk molding compound) composite flooring is made of unsaturated resin, low shrinkage agent and fiber material with threaded steel bar skeleton. It is widely used in large pig farms in more than 20 provinces such as Guangdong and Sichuan27.

Performance characteristics: flat surface without pores, strong corrosion resistance, load-bearing capacity of up to 1000 kg/board, and service life of more than 15 years. Its unique leakage hole design is a trapezoid with small top and large bottom, which does not hurt pig's trotters and has a manure leakage rate of more than 90%72.

Application scenarios: Mainly laid in sow farrowing beds, nursery beds and fattening pens, its excellent thermal insulation can reduce piglet diarrhea and significantly improve the survival rate7.

Installation advantages: No beam support is required, only four corners need to be fixed, which greatly reduces the installation cost7.

2. Cast iron floor: a classic choice of durability and non-slip
Traditional cast iron floor has regained favor through structural innovation. The Puzzle system of Eliopig, Italy, adopts a heightened full-slit design, combining strip slits with large square slits (side length 16-20mm), and adds a "center of gravity retaining block" to strengthen the load-bearing capacity36.

Core advantages: High heat conduction efficiency, providing a cool lying surface for sows in summer; the surface anti-slip bump design, the friction is 40% higher than that of ordinary floors, effectively preventing sows from slipping68.

Innovative design: The diamond-shaped manure cleaning port is matched with an adjustable cover to achieve rapid and centralized manure cleaning, avoiding bacterial growth caused by manure retention8.

Applicable scenarios: suitable for farrowing houses and fattening houses, especially suitable for high temperature and high humidity areas

3. Three-edged steel floor: precise protection of sow safety
The three-edged steel floor designed for Farrowing Pens consists of vertical beams, horizontal beam frames and reinforcing ribs. The three-edged steel bars are arranged in parallel at intervals of 9-11mm and laid flat upward94.

Scientific structure: The spacing between the ribs is precisely controlled to avoid pinching the sow's nipples and preventing the piglet's hooves from getting stuck. The back reinforcement ribs make the single board bear a load of 500kg, meeting the load-bearing needs of lactating sows94.

Convenient function: one end is equipped with a flip-up board (2400×700mm specification) to facilitate manual cleaning of manure and dirt; the hook-type design enables quick disassembly and assembly9.

Core value: reduce the injury rate of lactating sows and increase the survival rate of piglets by more than 15%.

4. Plastic floor: representative of lightweight and automation
Engineering plastic floor is mainly divided into two categories:

Static type: made of PP/PE material with anti-aging agent, common specifications are 400×600mm to 700×600mm, and weigh only 1.45-2.26kg/piece. The temperature difference between day and night is small, reducing cold stress of pigs1.

Dynamic type: The mobile plastic floor developed by Hunan Liaoyuan Company adopts canvas core conveyor belt, which moves in a cycle under the action of driving roller. With the scraper system, it can realize automatic separation and cleaning of feces and urine, reducing sewage discharge by 90%510.

Application scenario: static board is suitable for nursery pens; mobile system is suitable for high-density fattening farms, controlling ammonia concentration from the source110.

Comparison summary: Matching on demand is the key
Floor type Service life Core advantage Best application scenario
BMC composite board More than 15 years High load-bearing, easy to install Delivery bed/nursery bed
Cast iron floor 30 years Extremely wear-resistant, fast heat dissipation Delivery house/high temperature area
Triangular steel floor 10-15 years Anti-injury, can be turned over Sow delivery pen
Plastic floor 3-5 years Lightweight, small temperature difference Nursery pen/automatic pig house
Experts from the Institute of Animal Husbandry of the Chinese Academy of Agricultural Sciences pointed out that the selection of flooring needs to match the growth stage of pigs-BMC or triangular steel flooring is preferred for delivery rooms and nursery pens, while cast iron and mobile plastic systems are suitable for fattening areas7.

With the large-scale development of the breeding industry, composite materials and intelligence have become the new direction of floor evolution. Actual measurements of a pig farm with 10,000 heads in Hebei show that scientifically matching floor systems can reduce the incidence of pigs by 25% and increase breeding efficiency by more than 30%.

The technological revolution under the pig's trotter is quietly reshaping the future of China's breeding industry. Qingdao Puhui will also continue to innovate and inject new vitality into the market.
