dc.description.abstract An inclusive measurement of the average multiplicity of bb pairs from gluons, gbb, in hadronic Z0 events collected by the DELPHI experiment at LEP, is presented. A counting technique, based on jet b-tagging in 4-jet events, has been used. Looking for secondary bottom production in events with production of any primary flavour, by requiring two b-tagged jets in well defined topological configurations, gave gbb = (0.21 +/- 0.11 (stat) +/- 0.09(syst)) %. This result was checked with a different method designed to select events with four b quarks in the final state. Agreement within the errors was found.
