Products : Laboratory - MESURES QUALITÉ

Shell color

• Chromameter measurement
• 3 color scales:
  • L = black/white contrast
  • a = green/red contrast
  • b = blue/yellow contrast

Shell strenght

• Egg and shell weight
• Shell Index
• Shell thickness
• Static stiffness and fracture force (with compression machine)
• Dynamic stiffness (Kdyn)

HU

• HU = Haugh Units
• Albumen heigh (H) measured with tripod
  • HU = 100 log (H-1.7p(^0.37)+7.57)
• White firmness representative measurement
  

VMS (Vitelline membrane strength)

• Realized by compression machine
• Necessary force measurement to break the vitelline membrane

Data collection

Each bone is individually identified:

• Bone weight with precise balance (0.01g)
• Flexion bone measurement
• Bone dry matter and mineral matter
  • Bones find crushing and several repetitions per bone

• Color
• pH
• Water losses quantification during storage
• Meat stiffness notation

To increase the precision in your poultry zootechnical expertise:

• Litter dry matter measurement
  • Wood shaving
  • wheat straw
• Representative sampling method
• Several repetition of each sample for best precision
