Abstract:

Morbidity, mortality, medical treatment, and weight gain records for 748 calves originating in the southeastern United States and fed 56 days in a southern California feedlot were analyzed. The total number of calves that became sick on each day of the feeding period was tabulated as was the number of calves that became sick from one to four times during the feeding period, and the number of calves that become sick on each day. The relationship between the calves weight gains and the amount of sickness they suffered was established. Data on the amount of sickness in animals were compared to the mean weight gain of those animals. Patterns of sickness occurrence and duration were established.
