- •
Meta-analysis was performed on starch digestion data in the rumen, small intestine and hind gut of dairy cows.
- •
Rumen starch digestibility was affected by starch source and decreased with increasing starch intake.
- •
Small intestinal starch digestibility was affected by starch source and positively correlated to rumen starch digestibility.
- •
Hind gut starch digestibility was positively correlated to rumen starch digestibility but not affected by starch source.
- •
The meta-analysis provides a starch digestion sub-model that can be used in mechanistic non-linear feed evaluation systems.
