Selection Criteria and Considerations for Pig Farming Equipment

Considerations for pig farming equipment:

1. Asia’s climatic conditions vary significantly: due to the region’s highly variable climate, natural conditions are undergoing diverse changes. The north experiences cold, dry winters, while the south has hot, humid summers. In some areas, severe storms and typhoons also occur, which can influence pig housing design and the selection of climate control systems.

2. Poor insulation or air leakage: If a pig house has inadequate insulation or leaks, it may maintain a stable temperature under favorable conditions, but poor ventilation often occurs, leading to an accumulation of harmful gases and increased humidity, thereby raising the risk of respiratory diseases. In general, when the cooling system of a pig house suffers from poor insulation or air leakage, its performance is subpar.

3. Regulations on pollution, emissions, and odors: The rapid development of the livestock industry will inevitably give rise to corresponding regulations covering pollution, emissions, odors, resource management, and animal welfare. These regulations are likely to be implemented soon; therefore, they should be taken into account when designing pig farms.


Factors to consider when purchasing pig farming equipment:

1. Disinfection equipment
The on-site cleaning and disinfection equipment commonly used in pig farms includes high-pressure cleaners, flame sterilizers, and backpack sprayers. Combining flame sterilization with chemical disinfection yields excellent results. After chemical disinfection, applying a flame sterilizer can achieve a disinfection rate of over 95%.

2. Pig farm cooling equipment
Although ventilation is an effective cooling method, it can only reduce indoor temperatures to levels close to the outdoor ambient temperature. Currently, common cooling systems used in pig farms include wet‑pad fan cooling, misting cooling, and drip‑irrigation cooling. Because the latter three systems generate high humidity, they are not suitable for farrowing rooms or breeding facilities. The wet‑pad fan cooling system is one of the most mature evaporative cooling technologies available today, with an evaporative cooling efficiency ranging from 75% to 90%, and it has been increasingly adopted worldwide.

3. Heating Equipment
There are two types of pig house heating: centralized heating and localized heating. Centralized heating is generated by a central heating system, with the heat transfer medium conveyed through pipes to radiators throughout the pig farm. Localized heating includes hydronic underfloor heating, electric heating panels, infrared lamps, and similar systems.

Ventilation equipment suitable for pig farms is typically large‑diameter, low‑speed, low‑power fans. This type of fan provides strong airflow, operates quietly, consumes little power, and is highly durable. When installing ventilation systems, the following considerations should be observed: (1) Prevent air short‑circuiting by avoiding mounting fans directly against walls or in areas where openings are located at the base, which can create bypass airflow; if exhaust is vented from one side, the opposite side should be equipped with an intake to ensure proper air circulation. (2) Position exhaust vents on opposite sides of the pig house to prevent discharged air from being immediately drawn back into the adjacent pen. (3) Aim to direct airflow across as much of the pig house’s interior space as possible, particularly over manure channels, while minimizing dead zones to achieve effective ventilation.

4. Cleaning Equipment
Modern pig farms typically manage manure and urine by channeling them into drainage ditches. After pigs urinate on the manure‑permeable layer, the urine flows through the gaps into the manure ditch, while the solid manure remains on the permeable surface. When stepped on, it automatically falls into the underlying manure collection system. This design helps minimize contact between pigs and manure, thereby helping to prevent and reduce the incidence of disease.
