^a,b,c,d,e,fMeans within a column with different superscripts differ (P < 0.05).

^*Based on 310,002,578 pigs at 20 U.S. processing facilities over 48 consecutive months of data collection.

^†Total dead = dead on arrival + euthanized on arrival + dead in pen.

^‡Non-ambulatory pigs were defined as a pig unable to move or keep up with the rest of the group from unloading to stunning.

^||Total losses = total dead + non-ambulatory.
