¹: standard errors of estimates are presented between parenthesis; AgFiKid: age at first kidding in months; Int12Kid: interval between first and second kiddings in months; Int3toKid: interval between second, third, and remaining kiddings in months; IntAllKid: interval between all kiddings in months;${\mathsf{\sigma }}_{\mathrm{a}}^2$: additive genetic variance;${\mathsf{\sigma }}_{\mathrm{pe}}^2$: permanent environmental variance;${\mathsf{\sigma }}_{\mathrm{e}}^2$: residual variance; ${\mathrm{h}}^2$: heritability; t: repeatability.
