This study adopts an output oriented Shephard Distance Function (SDF) to estimate Technical Efficiency (TE) in cattle feedlot under five distinct estimators (Data Envelopment Analysis /DEA/, Free Disposal Hull /FDH/, Order-m, Order-α and Bootstrap). The aim is to rank the efficiency estimates based on descending order of the TE estimates from the five estimators and test the hypotheses of mean difference across the estimators. In addition, the independent variables used in the feedlot system were also ranked based on magnitude to total cost. Results show initial cost of animal, feed cost, water cost, labour cost, depreciation, medicaments and cost of salt lick are ranked 1st, 2nd, 3rd, 4th, 5th, 6th and 7th, respectively, in terms of proportion to total cost. The study found a combination of inappropriate scale of production and managerial problems as the causes of inefficiency in the cattle feedlot. The study advocates for proper pricing of inputs, commensurate and timely utilization of inputs to avert input waste. Similarly, the study recommends up-scaling (178 cattle feedlot) and down-scaling (92 cattle feedlot) the cattle feedlot production owing to their operation at increasing and decreasing returns to scale, respectively, to attain enhanced efficiency.
