摘要：Less than half of cow/calf producers in south-central Oklahoma and north-central Texas utilize pregnancy testing. The objective was to illustrate to beef cattle producers the effect that pregnancy testing and the subsequent adoption of an effective culling practice on first-time open cows has on net profitability of the cow/calf enterprise.
