Table 2. Estimated microbiability $\left(m^2\right)$ and heritability $\left(h^2\right)$ with SE and P-values for DG, FC, and feed intake.

Trait	$m^2$	SE	P-value	$h^2$	SE	P-value
DG	0.28	0.13	0.01	0.42	0.14	<0.01
FC	0.21	0.14	0.01	0.19	0.13	0.08
FI	0.16	0.10	0.03	0.11	0.11	0.22

$m^2={\mathit{\sigma }}_{\text{m}}^2/{\mathit{\sigma }}_{\text{P}}^2,$ as defined by Difford et al. (2016).
