Expressed as LSMeans of percentages. Only Lactobacillus species with a relative abundance of >1% on one of the six sampling days are presented here. Values followed by different capital letters in the same row differ significantly (P ≤ 0.05).
b
No significant interaction between day and diet was observed.
