At the end of the growout phase of broiler production essentially all broil
ers are caught and loaded into coops or cages entirely by hand. The catchin
g of broilers remains one of the few aspects of broiler production not yet
automated. Vacuum systems, permanent conveyors recessed-in the floors of gr
owout facilities, collecting mats, scoops, and self-propelled, combine-type
devices have been tried with little success over the past 30 yr, Renewed e
fforts at developing mechanical broiler harvesters have been encouraging in
recent years. Several equipment companies in North America and Europe have
developed prototype mechanical harvesters that appear to have promise. The
benefits of mechanical harvesting as compared to hand catching include low
er costs and improved working conditions. in addition, studies conducted th
us far indicate that mechanical harvesting will improve bird welfare both f
rom a stress and injury standpoint.
