The inclusive production of b-jets with a Z boson is an important background to searches for the Higgs boson in associated ZH {yields} llb{bar b} production at the Fermilab Tevatron collider. This thesis describes the most precise measurement to date of the ratio of inclusive cross sections {sigma}(p{bar p} {yields} Z + b-jet)/{sigma}(p{bar p} {yields} Z + jet) when a Z boson decays into two electrons or muons. The measurement uses a data sample from p{bar p} collisions at the center of mass energy {radical}s = 1.96 TeV corresponding to an integrated luminosity of 4.2 fb{sup -1} collected by the D0 detector. The measured ratio {sigma}(Z + b-jet)/{sigma}(Z + jet) is 0.0187 {+-} 0.0021(stat) {+-} 0.0015(syst) for jets with transverse momentum p{sub T} &gt; 20 GeV and pseudorapidity |{eta}| {le} 2.5. The measurement is compared with the next-to-leading order theoretical predictions from MCFM and is found to be consistent within uncertainties
