LAB 3.5 Break Joints & Evisceration
PLAY VIDEO
Decapitation - at skull:atlas joint (atlas = first cervical
vertebra).
Remove feet at break joint (distal metacarpal epiphysis or
knob of cannon
bone). With older sheep, the slaughterer cannot cut through the
cartilage
between the epiphysis and diaphysis (ie. between knob and shaft at the
lower or distal end of the long cannon bone), so the cut is made
through
the joint between the cannon bone and the digits. This leaves the
condyles
(spools) easily visible on the carcass.
Carcass suspension by gambrel under Achilles tendons
Slit sternum & free oesophagus
Bunging - freeing the anus
Remove penis or mammary tissue
Remove intestine, rumen, liver, and then cut through diaphragm
to get
the plucks (heart, lungs and trachea).
Kidneys stay on carcass but are exposed for inspection.
Bend back metacarpals against front shank to improve shoulder
shape.
