Partial uterine prolapse associated with uterine foreign body in a cow.

After correction of partial uterine prolapse in a Holstein cow, a 6-cm-long twig was found deep in the affected uterine horn. The twig was removed, and calcium-dextrose and penicillin G were administered. Recovery was unremarkable. Other reports of uterine foreign bodies in cows are scarce and do not describe uterine foreign bodies associated with uterine prolapse or invagination.
