Original publication title: Congenital, Inherited Bilateral Amastia in a Quarter Horse Mare.
- Species:
- horse
Plain-English summary
A 3-year-old Quarter Horse mare was found to have congenital amastia, which means she was born without developed mammary tissue. This condition seems to run in her family, as her mother also had the same issue, indicating it might be caused by a genetic mutation. When the mare was examined, she also had a pus-filled vaginal discharge due to a condition called pyometra, which is an infection of the uterus. The outcome of the treatment for her conditions is not specified in the abstract.
Abstract
Congential amastia, a medical condition in which mammary tissue fails to develop, was detected in a 3-year-old Quarter Horse mare. The dam of the mare was also afflicted with amastia, suggesting that the condition was due to an inherited genetic mutation as noted in other species. In addition, on presentation the mare had a purulent vaginal discharge secondary to a pyometra.
