Table 1.

Phenotypes (de-regressed estimated breeding values (EBVS)) of four porcine reproduction traits.

Trait a	Mean	SD	N	Mean Reliability b	h2
LSB	−0.015	0.526	1067	0.435	0.158
LWB	−0.061	0.099	1067	0.421	0.161
LWW	0.062	1.147	1067	0.511	0.173
LSW	1.604	6.454	1067	0.389	0.140

^a: LSB = litter size at birth, LWB = litter weight at birth, LWW = litter size at weaning, LSW = litter weight at weaning; ^b: reliability of EBV values.
