Animal And Objective: The objectives of this study were to produce hematological reference intervals for late-pregnancy sows and to assess whether there were associations between sow hematological end points and the number of stillborn pigs.
Procedure: Whole blood was collected from 272 healthy pregnant sows ~1 wk before farrowing, and complete blood (cell) counts and hemoglobin determinations were obtained. Sows were monitored during farrowing, and litter characteristics, including number of stillborn piglets, were recorded.
