Additive genetic covariance between average daily gain in rabbits fed ad libitum (ADG_AL) and abundance of the most important OTU: total additive covariance (\({\upsigma }_{{\mathrm{u}}^{*},\mathrm{AL},\mathrm{M}}\)), direct effects (\({\upsigma }_{\mathrm{u},\mathrm{AL},\mathrm{M}}\)), and indirect effects (\({\uplambda }_{\mathrm{AL}\leftarrow \mathrm{M}}\times {\upsigma }_{\mathrm{u},\mathrm{M}}^{2}\))
