- •
A meta-analysis regarding the impact of forage particle size (FPS) on chewing activity and rumen fermentation of dairy cattle.
- •
A meta-regression was conducted to test the heterogeneity of the results.
- •
Coarse FPS improved chewing activity and ruminal fermentation.
- •
Decreasing FPS was more influential in high level of forage and hay-based diets.
