Complete Collection of Pig Pen Design Drawings and Construction Layout Plan Reference

As temperatures gradually rise, some friends planning to get into pig farming this year need to start building their pig farms. Starting today, we are launching a series of articles on pig farm construction, beginning with the design and construction of pig pens for deep-litter pig farming.

The current basic rearing model for deep-litter pig farming is to set up an 80-100 cm underground or above-ground litter pit inside the pen, filled with litter such as sawdust or straw and other agricultural by-products, and use microbial agents to ferment the litter, creating a small environment for beneficial bacteria to multiply, suppressing and decomposing harmful bacteria, including bacteria and viruses; pig manure and urine are discharged directly onto the litter, achieving zero discharge of manure and sewage.

The manure and urine accelerate the fermentation of microorganisms in the litter, generating heat and ensuring that the pigs can overwinter normally; it restores the pigs' rooting and feeding habits, as they consume the microbial protein produced by fermentation, which becomes a supplementary feed for the pigs; the litter is cleaned out once after a relatively long period (generally 2-3 years) as needed, becoming high-grade organic fertilizer; the entire rearing process achieves zero discharge, no odor, and no pollution externally.

Pig pen architecture is a profound science that requires continuous summarization and refinement. For the pig pen architecture of ecological pig farming, it is necessary to combine the excellent achievements of traditional pig pen design, but at the same time, do not use traditional thinking patterns to limit our design ideas; it is necessary to use creative thinking to guide and continuously innovate pig pen design.

I. Basic Concepts of Deep-Litter Pig Pen Design

A scientific ecological natural pig farming pig pen should maximize the use of natural resources, such as sunlight, air, airflow, wind direction and other free natural elements, and minimize the use of modern energy or substances such as water, electricity, and coal; maximize the use of biological and physical transformations, and minimize the use of chemical transformations.

II. Guiding Ideology of Deep-Litter Pig Pen Design

First, it is conducive to giving play to its role, saving labor, and improving efficiency. Second, it is conducive to saving land area and controlling the appropriate density of pigs. Third, it is conducive to the growth and development of various types of pigs, improving the climate environment inside the pen as much as possible. Fourth, control the appropriate construction cost.

III. Basic Principles of Deep-Litter Pig Pen Design

The design of ecological natural pig farming pig pens also requires considering the following principles in advance, and these principles all need to be guaranteed by the production system and pens: First, the "zero" mixing principle. Pigs from different sources are not allowed to be mixed, which requires consideration of the preparation of isolation pens. Second, the optimal stocking principle. Always maintain the utilization of the pens, which requires the determination of a balanced production system. Third, the principle of grouping pigs by age: pigs at different stages cannot be together, which is the foundation of the all-in-all-out system.

IV. Requirements of the Internal and External Environment on Deep-Litter Pig Pen Design

The environment of the pig pen mainly refers to temperature, humidity, gases, light, and other sanitary conditions that affect the environment, which are important factors affecting the growth and development of pigs. Between the pig collective and the environment, there is always an exchange of matter and energy. Under normal circumstances, the pig body can maintain balance with the environment, forming a virtuous cycle, which can prompt pigs to exert their growth potential. Therefore, to ensure the normal life and production of the pig herd, it is necessary to artificially create climate conditions suitable for the physiological needs of pigs.

The architectural design of ecological natural pig farming is not much different from the site of traditional intensive pig farms, and is more flexible than traditional pig pens. It should mainly comprehensively consider and analyze issues such as geographical location, terrain and topography, soil quality, water, electricity, and land area.

V. Principles of the Overall Layout of Deep-Litter Pig Pens

1. Conducive to production: The overall layout of the pig farm should first meet the requirements of the production process, planning and arranging buildings according to the sequence and continuity of the production process, which is conducive to production, facilitates scientific management, and thus improves labor productivity.

2. Conducive to epidemic prevention: Large-scale pig farms have large pig herds and high rearing density. To ensure normal production, sanitary and epidemic prevention work must be raised to the primary position. On the one hand, the overall layout should focus on several aspects such as the nature of the pig farm, the resistance of the pigs themselves, terrain conditions, and dominant wind direction, and reasonably arrange buildings to meet their epidemic prevention distance requirements; on the other hand, of course, some effective epidemic prevention measures should also be taken. Natural pig farming methods should use as many biological and physical measures as possible to improve the epidemic prevention environment.

3. Conducive to transportation: The daily transportation tasks of feed, pigs, and production and living supplies on the pig farm are very busy. In the layout of buildings and roads, the internal connections of the production process and the continuity of external connections should be considered, so that transportation routes are convenient, concise, non-repetitive, and non-circuitous.

4. Conducive to living management: In the overall layout of the pig farm, the production area and the living area should be both separated and connected, with a moderate location and a relatively quiet environment. It is necessary to create a comfortable working environment for employees, while also facilitating living and management.

Editor's Comments

The deep-litter pig farming model has advantages and disadvantages, depending on what you are pursuing. Is it to reduce labor input? Or is it to strive to reduce the occurrence of pig diseases? If it is the former, deep-litter pig farming cannot meet your requirements, because it is not "lazy man's pig farming"; if it is the latter, it has indeed played a certain role.
