This disease is associated with metabolic disorders, liver damage and belongs to the group of serious diseases. Most often it occurs in pigeons after ingestion of grain affected by toxins.
High-calorie diets, inadequate supply of vitamins and amino acids, and content in cramped cells increase the manifestation of the disease.
Pigeons of meat breeds are more prone to obesity, which occurs with the formation of thick fatty layers on the lower abdomen, between intestinal loops and in other parts of the body, fat is also deposited in the cells of tissues (in the liver, spleen and walls of blood vessels).
In case of a disease, the liver, spleen and yolks of the eggs burst at the slightest concern, since the cells of the tissues do not have sufficient elasticity and, in the case of a minor injury, overstrain. Upon rupture, bleeding is detected, which leads to the death of the bird from loss of blood.
For therapeutic and prophylactic purposes, it is recommended to observe the norms of provision with vitamin E (10 mg per 1 kg of feed).
