Feedlot performance records from the U.S. Meat Animal Research Center feedlot for 1993 through 2000 were analyzed to evaluate the impact of foot rot on ADG and total days on feed. Records from the original pool of 36,755 bull, steer, and heifer calves were sorted so that only steers that had a single foot rot incidence and no other morbidities were included in the data set (7,100 steers). To roughly pattern these data to industry production practices, time of foot rot insult during feeding was divided into 3 production periods: starting (0 to 60 d), growing (61 to 120 d), …
