Let’s explore what we know about the relationship between winter ventilation, fuel costs and ammonia, and how together they can greatly impact bird welfare and performance.
Higher litter moisture = Increased Ammonia
Fuel = greatest single producer expense
Decreased ventilation for fuel savings ≠ profitability
The primary goal of winter ventilation is to remove moisture. Increased moisture will increase ammonia generation, creating multiple welfare and performance challenges.
Condemned paws cost the industry $250-300M annually
Body weight losses of 0.50 lbs at 7 weeks have been documented
1/2 pound of weight = $430,000 weekly (based on 1M birds processed)
Incoming cold air travels along the ceiling, mixes with warmer air and moisture is properly ventilated.
Static pressure: 0.08 – 0.12
Sidewall vent open: 1 – 2 inches
Relative humidity: 40-60%
Cold air immediately falls when entering the house, depositing moisture along the sidewalls.
Static pressure: <0.08
Sidewall vent open: < 1 inch
Relative humidity: < 40 or > 60%
The Role of Litter Amendments
Using PLT® allows producers to ventilate for moisture, not ammonia, which can create a $400-600 savings per flock due to fuel savings. Less ammonia, moisture and fuel use equals increased animal welfare and sustainability.
