Additive genetic covariance between average daily gain in rabbits under restricted feeding (ADG_R) and abundance of the most important OTU: total additive covariance (\({\upsigma }_{{\mathrm{u}}^{*},\mathrm{R},\mathrm{M}}\)), direct effects (\({\upsigma }_{\mathrm{u},\mathrm{R},\mathrm{M}}\)) and indirect effects (\({\uplambda }_{\mathrm{R}\leftarrow \mathrm{M}}\times {\upsigma }_{\mathrm{u},\mathrm{M}}^{2}\))
