Statistics of significant differently expressed miRNAs.

Sample 1 vs. Sample 2	Up a	Down b	Total	Shared
WRRh vs. WRRl	116 (47)	84 (24)	200 (71)	80 (22)	26 (16)
XHh vs. XHl	129 (44)	150 (40)	279 (84)
WRRh vs. XHh	130 (31)	127 (47)	257 (78)	110 (39)
WRR vs. XHl	137 (41)	160 (60)	297 (101)

^a The numbers of miRNAs expressed in sample 1 more than sample 2; ^b The numbers of miRNAs expressed in sample 1 were lower than sample 2. The value in brackets is the number of novel miRNAs. WRRh vs. WRRl indicated the comparison between the two-tail samples of Recessive White Rock; XHh vs. XHl indicated the comparison between the two-tail samples of Xinhua Chickens; WRRh vs XHh indicated the comparison between the groups of Recessive White Rock and Xinhua Chickens with high body weight; WRRl vs. XHl indicated the comparison between the groups of Recessive White Rock and Xinhua Chickens with low body weight.
