A combination of active substances that improve digestion and help moulting.
Trichomoniasis is caused by the protozoan Trichomonas columbae. It is a single-celled organism that lives in the digestive tract of pigeons, especially in the throat and goiter. The microbe is sensitive to the outside environment, surviving only a few minutes outside the pigeon's body. This helps to control the disease and means that the bird cannot become infected from the farm or the environment as is the case with other diseases (worms or salmonellosis). The trichomonad organism requires contact between birds to spread from one bird to another, usually transmitted through saliva or goose milk. Saliva contaminates food and water. When the pigeon drinks, the microorganism is released through its beak and, when another pigeon comes to drink water, it ingests the trichomonad organism. When a pigeon searches through food, every grain it touches is infected with this microorganism which is then automatically transmitted to the next pigeon. The disease is also transmitted by touching the beaks of an infected pigeon or when parents feed their young.
The stress of the competitions will put any unitary system to the test. Depending on the degree of stress, the level of trichomonads increases and decreases. When the level is high the pigeon can also develop secondary infections, especially respiratory infections, which will compromise performance in competitions. It also produces a toxin that will make the bird feel unwell. Birds with a high level of trichomoniasis are said to have "wet trichomoniasis". The signs of the disease are subtle and varied.
