Canker (Tricomoniasis) has become the leading cause of poor performance in
racing pigeons. The incidence of the disease is steadily rising. More and more
pigeon fanciers are becoming aware of the problem because they are regularly
having their pigeons tested at the vet. It is becoming clear to vets and pigeon
fanciers that some pigeons carry resistant strains of Crop-Canker that is not
being controlled by any of the conventional Crop Canker medications.
proved conclusively that the problem of resistance to currently available
medication was a world wide problem. Because Crop Canker is a true sub clinical
disease that will often have no specific clinical signs and because racing
pigeons are constantly in contact with other pigeons it is impossible to
eradicate Trichomonas. To perform well in pigeon racing the fancier is forced to
medicate regularly against Trichomonas in order to reduce the incidence in his
lofts. The use of single day medication against Trichomonas is popular as it
saves time and is often more affordable to the fancier. Although some single day
medications are still very effective the use of these products do play a
significant role in the development of resistant Trichomonas.
all the Crop Canker medications are derived from the same group of medicines -
this enhances the potential for cross-resistance between medications. This means
that if a certain Trichomonas organism is resistant to one Crop Canker product
the chances that it will be partially or totally resistant against the other
product are very high.
