Data collected during the present study shows that the
efficiency of the IOBW was due solely to washing (3
L/carcass). In their report on commercial bird washers,
Bashor et al. (2004) found that the volume of water used
per carcass in commercial IOBW ranged from 2.2 to 9.1
L, and efficiency of washing was not related to the volume
of water. These authors also found that the washer pressure
in commercial IOBW ranged from 40 to 180 psi, with
an overall average pressure approaching 80 psi (Bashor et
al., 2004). The only difference between commercial IOBW
and the one used in the present study involves the orientation
of the carcasses. The IOBW used in the present study
orients the carcass in the opposite position from that used
in commercial IOBW, and this allowed water to drain
from the body cavity. This orientation seemed to prevent
internal water entrapment, which could improve the efficiency
of the wash.
