Congenital goiter in sibling goat kids

Abstract

History: Nine, adult, female Boer goats were presented to the University of California, Davis, Veterinary Medical Teaching Hospital for timed artificial insemination. To synchronize their estrous cycles, the owner gave each doe 7.5 mg dinoprost tromethamine (Lutalyse®) intramuscularly 12 hours prior to presentation and 24 hours prior to removal of the doe’s progesterone controlled intravaginal drug release device (EAZI-BREED™ CIDR®). Approximately 52 hours after prostaglandin administration, one of the does delivered two live kids, one female and one male, without complication. The neonates were unexpectedly premature by approximately two weeks. Both kids exhibited bilateral, smooth swelling at the laryngotracheal junction and generalized alopecia. Both kids were euthanized, and they were sent to the UC Davis Anatomic Pathology Service for necropsy.
