To improve processes, how
debone yield data is collected needs
to be reviewed. If only cumulative
department data, whether by shift or by
day, is available, then a more detailed
procedure should be implemented.
A frame scrape test procedure
would be one way forward. Frame
scrapes are an objective method of
measuring where, and how much,
meat is being left on the frame.
Improving scrape test scores can
drive debone yield.
Scrape test steps
The first step in the scrape test
is the collection of six consecutive
frames from a debone line, as
consecutive frames supply an
average of the wing scorers and
Providing feedback to line workers can
lead to better yield on turkey and broiler
debone lines.
cutters. Next, a beginning weight for
the six frames needs to be recorded.
This is followed by scraping
excess meat from each of the
different areas of the frame and
recording the individual weight for
each of those areas. These areas are
the pulley bone, the eye meat, the
scapula, the rib and the keel.
An initial period of testing will
be required to establish a baseline,
and then a goal (usually slightly
better than the current scrape test
results) is set. This data can be used
to track whether progress is made
over a given period.

Speak to employees
Method and frequency of data
provision to employees on the
debone line needs to be established,
and the best method may be to
provide visual feedback as often
as possible, but not less than three
times a week.
Decisions also need to be
taken on how data is displayed,
for example, average grams, as a
percentage of frame, etc, and every
effort should be made to convey
what the numbers should be. The
same results can be achieved by
colour coding posted numbers.
Employees should be trained to
understand which results they are
responsible for when working on a
given line position and a number of
benefits can be expected once the
system has been implemented.
