Litter Conditioning & Ammonia Abatement

Execute intensive litter raking conditioning.

Overview & Core Concepts

Day 20 prioritizes intensive floor and litter management. As broilers reach nearly 1 kg, daily manure output reaches peak intensity. Active litter conditioning, crust decaking, and targeted ventilation are mandatory to safeguard footpads and breast blisters.

Key Performance Indicators (KPIs)

Achieving optimal management targets requires strict adherence to environmental parameters.

Expected Weight
950g
Feed Intake
158g/bird
Water Intake
284ml/bird
Temperature
21-22°C
Humidity
50-65%
Lighting Schedule
18L:6D at 10 lux (consistent dark period prevents continuous manure deposition in sleep zones)
Feed Type
100% Grower Pellet (2.5–3.0mm, 20.5% CP, 3125 kcal/kg ME)

Why This Matters

Wet, compacted litter releases high ammonia and creates chemical burns on footpads (pododermatitis) and hocks. Clean, dry litter preserves bird mobility, prevents downgrades at processing, and keeps the shed environment healthy.

Execution Checklist

Observations & Key Indicators

Observe spacing, activity levels, and physical indicators:

Healthy Signs

  • Litter is loose, friable, and aerated with a dry top layer that moves freely under bird scratching.
  • Bird footpads are clean, pliable, flesh-colored with zero brown staining or black lesions.
  • Flock rests comfortably on dry bedding with breast feathers clean and white.
  • House ammonia reading remains strictly below 10 ppm throughout the day and night.
  • Birds walk freely without limping, stiffness, or reluctance to approach feeders.

Warning Signs

  • Litter surface forms a sticky, rubbery, or greasy black cake (slick capping).
  • Brown necrotic erosions or blackened ulcers on bird footpads or hock joints.
  • Strong ammonia odor stinging eyes during morning walkthrough before lights turn on.
  • Birds reluctant to walk, sitting continuously on wet litter with dirty, stained breast feathers.

Next Stage Handoff (Day 21)

Tomorrow, your operation reaches Day 21. The primary management objective will be:

Conduct comprehensive 21-day flock weighing audit (1,000–1,050g target), calculate coefficient of variation (CV >80% uniformity), evaluate 3-week FCR, and audit skeletal integrity.
