Ventilation, PLT & Animal Welfare

By diciembre 11, 2018News, PLT
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

Winter Ventilation

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.
