We use data collected by the CLEO III detector at the Cornell Electron Storage Ring to measure the inclusive yields of Ds mesons as B(Υ(5S)→DsX)=(44.7±4.2±9.9)% and B(Υ(4S)→DsX)=(18.1±0.5±2.8)%. From these measurements, we make a model dependent estimate of the ratio of Bs(*)B̅ s(*) to the total bb̅ quark pair production of (16.0±2.6±5.8)% at the Υ(5S) energy.
