The associated production of a Z boson or an off-shell photon $\gamma^*$ witha bottom quark in the forward region is studied using proton-proton collisionsat a centre-of-mass energy of $7{\mathrm{\,Te\kern -0.1em V}}$. The Z bosonsare reconstructed in the ${\text{Z}/\gamma^*}\!\rightarrow{\mu^{+}\mu^{-}}$final state from muons with a transverse momentum larger than$20{\mathrm{\,Ge\kern -0.1em V}}$, while two transverse momentum thresholds areconsidered for jets ($10{\mathrm{\,Ge\kern -0.1em V}}$ and$20{\mathrm{\,Ge\kern -0.1em V}}$). Both muons and jets are reconstructed inthe pseudorapidity range $2.0 < \eta < 4.5$. The results are based on datacorresponding to $1.0{\,\mbox{fb}^{-1}}$ recorded in 2011 with the LHCbdetector. The measurement of the Z+b-jet cross-section is normalized to theZ+jet cross-section. The measured cross-sections are \begin{equation*}\sigma(\text{$\text{Z}/\gamma^*(\mu^{+}\mu^{-})$+b-jet}) = 295 \pm60~(\text{stat}) \pm 51~(\text{syst}) \pm 10~(\text{lumi}) {\,\mbox{fb}}\end{equation*} for ${p_{\rm T}}$(jet)$>10{\mathrm{\,Ge\kern -0.1em V}}$, and\begin{equation*} \sigma(\text{$\text{Z}/\gamma^*(\mu^{+}\mu^{-})$+b-jet}) =128 \pm 36~(\text{stat}) \pm 22~(\text{syst}) \pm 5~(\text{lumi}) {\,\mbox{fb}}\end{equation*} for ${p_{\rm T}}$(jet)$>20{\mathrm{\,Ge\kern -0.1em V}}$.
