Note: Nor_Reads: Normalized reads, the results of Solexa sequencing, Normalization formula: Normalized expression = Actual miRNA count/Total count of clean reads×1,000,000; F_change: Fold_changes (Log2 Late lactation/Peak lactation), fold changes of miRNAs in both samples, – represents down regulation in late lactation; P_Value: P values manifest the significance of miRNAs differential expression between two samples; Sig_level: Significance_level, # represents no significant difference, * represents significant difference;
