Key ways
to reduce
yield loss of
processed
chickens
Careful handling of broilers
from the farm to the slaughter
can help to minimize losses.
EDUARDO CERVANTES LÓPEZ

S

everal factors, from harvesting to stunning, can
contribute to reduced yields and lower final
output at the poultry processing plant. However,
where bird handling and bird stress are concerned,
these factors are easy to remedy.

Harvesting on farm
Broilers must be kept as calm as possible during
harvesting.
On some farms, dividers are not installed at the
start of rearing and, because of this, birds must be
physically separated when capture takes place. To do
this, the harvesting team usually brings in large sheets
or frames with plastic meshes, moving very quickly to
catch and load the broilers as fast as possible.
This can stress and panic the birds and they will try
to escape, flapping their wings and rising one on top of
the other, which can result in their skin being torn.
To reduce this stress, dividers should be installed
across the narrowest space of a poultry house and, in a
house of 15 meters width, they can be installed in two
sections and moved using a conventional wheelbarrow

that has been adapted to have a third wheel.
Once in place, these frames can be moved manually or electrically as cages are filled. The aim is to
keep the remaining birds as close as possible to the
harvesting team, preventing time lost chasing birds,
stressing the birds, and tiring the workers, who will
then work more slowly.
Harvesting is usually carried out by carrying the
birds by one leg, or by holding the birds by the body
with the wings held tightly to it. During the former
method, there is the risk that birds will be harmed
due to wing flapping. However, the latter method
takes longer, requires more workers and has an
impact on costs, although this will be compensated
for by the lower number of birds rejected at the
processing plant.
Various recent studies have looked at whether birds
could be carried by one leg, but all have found there
will always be at least some wing flapping. But even
working at normal speed, i.e., quickly, flapping can be
kept to a minimum if workers keep their arms straight
and do not swing the birds.
