Abstract

The contamination of carcasses from milk is a sanitation con­cern in cattle packing plants. Previous research indicated the administration of estradiol and progesterone over a period of time, followed by injection of dexamethasone, may induce lac­tation in nulliparous dairy heifers. The objective of this study was to determine potential factors associated with lactation in feedlot heifer mortalities at one Kansas feedlot.
