What is the difference between 300 fattening pigs and 3,000 self-breeding pigs?
II. 300 head fattening pig farm
Land area: about 4-5 acres (including growing and fattening house + pig out platform)
Fattening house: divided into 3-4 buildings (all-in-all-out batch management)
Isolation area: sick pig isolation pen (5% capacity)
Auxiliary area: feed tower, pig out platform, fecal waste holding tanks
2. Core equipment
Pens system:
Large group pen design (15-20 heads/pen), pen area 0.8-1 m²/head
Leakage floor (cast iron/cement) + slope drainage
Environmental control:
Negative pressure ventilation system (axial fan + ventilation window)
Automatic spray cooling device
Feeding system:
Wet/dry feeders or automatic troughs
Centralized feeding tower + feeding cart
Other equipment:
Automatic waterer (2-3 per pen)
Manure collection ditch + solid-liquid separator
III. 3,000-head self-breeding farm (integrated)
1. Site planning
Land area: about 60-80 acres (including the whole process of breeding+conservation+fattening)
Functional area:
Breeding area: breeding house, gestation house, delivery house, nursery house
Fattening area: 6-8 buildings (all in and all out by batch)
Isolation area: independent isolation house (≥50 meters from the production area)
Environmental protection area: biogas pond, oxidation pond, organic fertilizer workshop
Management area: feed mill, decontamination center, laboratory, office area
Automatic system:
Fully automatic environmental control system (temperature and humidity, ammonia monitoring linkage fan/wet curtain)
Centralized feeding system (pipeline to each building)
Intelligent grouping system (RFID ear tag + automatic weighing and grouping)
Column configuration:
Farrowing crates: 300 (calculated by PSY=25)
Nursery crates: 600 (10-12 heads per bed)
Fattening pen: 300 pens (10-12 heads per pen)
Environmental equipment:
Biogas generator set (treating manure ≥ 50 tons per day)
Vertical fermenter (treating dead pigs/placenta)
Biosafety:
Three-stage decontamination center (vehicle-personnel-material separation)
Air filtration system (breeding barn)
In short, it is necessary to consider from the site layout, functional area division, equipment selection, environmental treatment, biosecurity, management process and other aspects to give a detailed and feasible program, while balancing the cost and efficiency.
