The chief objective of this study was to determine the actual death losses suffered by practical cattle feeders under feed-lot conditions.To this end, thirty-eight feeders who furnished the data used in this study were personally interviewed. These data involve 23,239 cattle fed by these operators from 1946 to 1951.The opinions of these feeders were accepted at face value.In some cases incorrect diagnoses may have been made.A further objective in this study was to secure information relative to the importance of different causes of death in these groups.Other factors such as rations fed, use of pastures, length of feeding period and other management practices may also be important factors affecting death risk.
