miR-25 expression is downregulated in goat mammary tissue from non-lactation to late lactation. Real-time PCR validated the expression levels of miR-17-5p, miR-25, miR-361 and miR-2340 in goat mammary tissue at non-lactation, early lactation, peak lactation and late lactation. The data were normalized to 18S. miR-25 expression at the non-lactation stage was set to 1.0. The error bars depict the mean ± S.D. of the samples with three goats at each stage
