Cow Relevant - Invitro Total Tract Starch
Digestibility (6mm grind)

• Sample preparation 70 of material is between 6
  8 mm grind.
• Best compromise between no grinding grinding to
  fine (1mm)
• Coarse grind 4 replicates/sample.
• Partitions Starch Digestibility in Ruminal Post

Cow Relevant - Invitro Total Tract Starch
Digestibility (6mm grind)

• Digested in Rumen fluid 12 hours.
• Invitro (in glass)
• Pooled Rumen Fluid. Collected from Four Dairy
  animals.
• Maximum collection time 20 minutes.
• One hour post feeding.
• Four replicates / sample.

Conclusions

• Starch Digestibility is an important nutritional
  component that can now be measured with
  confidence.
• Accounting for Starch Digestibility pro active
  in dealing with acidosis.
• Milk 2006 will adjust TDN for Starch
  Digestibility.
