Feed tray/feed bucket 30kg suspended feed bucket (anti-scraping design) 500 1 bucket for every 30 chickens (15,000÷30=500), height automatically adjusted with age
Feed tray Plastic shallow tray (40cm×60cm) 300 Used 3 days before brooding (1 tray for every 50 chicks)
🧼 IV. Manure cleaning and litter management
Equipment Specifications and configuration Quantity Processing capacity
Manure scraper system Chain-type automatic manure cleaning (power 3kW) 3 sets Manure ditch width 2.2m, daily manure cleaning volume ≥15 tons (moisture content 70%)
Bedding preparation Rice husk/wood chips (thickness 8cm) 120m³ Lay before chickens enter, humidity ≤25%
Manure treatment Fermentation tank (volume 50m³) 1 unit Aerobic fermentation into organic fertilizer to reduce environmental pollution
💡 V. Auxiliary equipment
Equipment Specifications and configuration Quantity Key role

Brooding fence Galvanized iron mesh (height 45cm) 800m Partitioned brooding (≤2,500 per zone), removed after 7 days of age
Spray disinfection machine Electric high pressure (30L/min) 2 units Disinfection of chickens (quaternary ammonium salt/iodine preparation), droplet diameter ≤80μm
Dead chicken treatment High temperature incinerator (volume 1m³) 1 unit Biosafety treatment, temperature ≥150℃
⚠️ VI. Key points of professional design and cost control
Chicken house layout optimization

Group management: 15,000 chickens are divided into 6 zones (2,500 chickens per zone), independent temperature control + drinking water system.

Ventilation calculation: Maximum ventilation volume in summer = chicken weight (kg) × 6m³/h (35 days old, calculated as 2kg, requires 180,000m³/h).

Energy-saving and consumption-reducing measures

Wet curtain-fan system with frequency converter (saving 30% electricity)

Gas heater installed with waste heat recovery device (thermal efficiency>90%)

Biosafety system

Three-zone division: clean zone (office), gray zone (equipment), dirty zone (manure field)

Entry process: shower→change clothes→disinfection (ozone air shower room)

💰 VII. Investment estimation (equipment part)

System Main equipment cost Percentage Remarks
Environmental control system ￥280,000~350,000 35% Including fan/wet curtain/intelligent controller
Drinking water system ￥85,000~100,000 12% Including nipple/pipeline/filter
Feeding system ￥180,000~220,000 25% Automatic feed line + feed bucket
Manure cleaning equipment ￥65,000~80,000 9% Manure scraper + fermentation tank
Auxiliary equipment ￥70,000~90,000 10% Disinfection/lighting/fencing, etc.
Total ￥680,000~840,000 100% Excluding civil engineering and breeder costs
Note: According to the market price in 2025, it is recommended to upgrade the equipment in stages for large-scale farms (core environmental control and feeding first, then automatic manure removal).

✅ Operational suggestions
Batch management: 5~6 batches per year (42 days per batch), empty house period ≥14 days (thorough cleaning + fumigation).

Data monitoring: record daily feed intake/water temperature/mortality rate, and control FCR (feed-to-meat ratio) at 1.55~1.65.

Emergency plan: backup generator (power ≥100kW), water reservoir (≥50m³) to prevent water and power outages.

This configuration can support more than 100,000 broilers per year, and the equipment life is 8~10 years (under regular maintenance). The plan needs to be fine-tuned according to the local climate (e.g., strengthening cooling in the south and focusing on heat preservation in the north).
