The use of EFEs promoted linear increases (P ≤ 0.048) of DM and NDF intake and tended to increase linearly (P = 0.077)
TDN intake (Table 2). However, EFE did not significant effect (P ≥ 0.379) on total-tract digestion of nutrients of dairy cows.
Additionally, EFE supplementation provided a linear increase (P = 0.001) in the intake of feed with particle sizes >19 mm,
besides a quadratic effect (P = 0.043) for intake of particles sizes 19–8 mm particle size. Overall, treatments quadratically
affected ruminating (P = 0.005) and chewing activity (P = 0.002) of animals (Table 3).
