Causes problems with feeding.
Trichomoniasis is also known as Canker (in doves and pigeons) and as Frounce (in raptors). T. gallinae is a parasite of the upper digestive tract of many avian species causing accumulation of necrotic material in the mouth and esophagus. It is principally a disease of young birds and is often fatal.
How do you prevent trichomoniasis in birds?
Prevention. Trichomoniasis can be controlled in a commercial/domestic flock by culling or treating carrier birds. Food and water sources, as well as bird baths, should be cleaned regularly and protected from contamination by wild birds. Generally parasitic trichomonads cannot survive drying out.
