The level of aggregation of reported data has limited the proper accounting of live animals in many livestock models, making the consistency of their underlying biologics suspect. The authors suggest an econometric methodology to decompose a wide range of aggregate data, and they apply this method to estimate a disaggregated average cattle slaughter weight for calves, cows, and other cattle from total beef production data in the European Union.
