Statistical association analysis of ovine PIGY gene CNV with growth traits of three Chinese sheep breeds.

Breeds	Growth Traits	CNV Type (Mean ± SE)			p
		Loss (n = 350)	Normal (n = 99)	Gain (n = 120)
CKS	Body weight (kg)	58.801 ± 3.084 a	54.280 ± 3.156 b	61.065 ± 3.353 aC	0.027 *
	Chest circumference (cm)	92.544 ± 2.036 A	89.076 ± 2.084 B	93.251 ± 2.214 AC	0.029 *
STHS	Circumference of cannon bone (cm)	6.872 ± 0.082 A	7.298 ± 0.116 B	7.342 ± 0.095 BC	0.000 **

^a,b Value that differ significantly at p < 0.05; ^A,B,C value that differ significantly at p < 0.01; * value that differ significantly at p < 0.05; ** value that differ significantly at p < 0.01. CKS: loss (n = 145), normal (n = 41), gain (n = 54). HS: loss (n = 131), normal (n = 22), gain (n = 15). STHS: loss (n = 74), normal (n = 36), gain (n = 51).
