Situation

Commercial broiler farming today, has eyes on higher and higher meat yields.

To satisfy the demand, farmers are driven to pack in higher bird densities (profit per sq. m.).

But under hot weather conditions, high bird densities leads to heat stress. A silent killer of broiler flocks.

Heat stress

Chicken have trouble getting rid of excess body heat at the best of times. Panting, flapping their wings, standing, eating less (through loss of appetite) are all behavioural attempts to correct the balance.

Under packed housing conditions, however, despite their efforts, the heat can get too much causing birds to die.

Airflow and fans

And so, in the recent years of intensive farming, farmers have embraced the use of circulation fans.

Circulation fans cause air movement which acts as a carrier for the birds’ excess body heat.

More air flow, the more heat removed.
