Fig 6. Changes in levels of 9 plasma exosomal miRNAs (A) and muscular miR-451 (B) of grazing and housed cattle analyzed by qRT-PCR.

Data of grazing and housed cattle are indicated as solid and broken lines in panel A, and green and purple columns in panel B, respectively. Different letters among the time points indicate differences at P < 0.05 in the grazing (x, y) and housed cattle (a, b). An asterisk and double asterisks indicate differences between the cattle groups at P < 0.05 and P < 0.01, respectively.
