Study protocol/Measurements

4. Carcass measurements

After reaching the pre-determined final weight an animal will be fasted for 16 hours with free access to water and then weighed before slaughter. Slaughtering will be done following the 'Halal' method. The carcasses will be eviscerated and all body components such as head, feet, skin, blood, visceral organs (kidneys, liver, heart, lungs), testicles, fat depots (scrotal fat, kidney and pelvic fat and omental fat), intestines, when full and empty, will be weighed.

The following carcass characteristics will be recorded:

  • Final weight
  • Fasting weight loss
  • Slaughter weight
  • Empty body weight
  • Hot carcass weight
  • Chilled carcass weight
  • Shrinkage weight loss
  • Dressing percentage
  • Proportion of whole sale cuts
  • Proportion of lean, bone and fat

  •  

    • Muscle/bone/fat ratios
    • Fat depth (of the 12th rib, 110 mm from the spinal cord).
    • Rib eye area
    • Fat thickness (at first and last rib and last lumbar vertebrae)
    • Non-carcass components
    • Carcass length
    • Leg length
    • Circumference of the buttock
