This disease is associated with the occurrence of depression and the accumulation of chickens together, but the expansion of the abdomen and thickening and necrosis of the navel are typical symptoms of this disease. Hyperemia of the yolk sac and lungs are also not observed in this disease, but what we encounter in all cases is the existence of a dilated and inflamed yolk sac that has not yet been absorbed and has an unusual appearance of a non-hemolytic Escherichia coli reservoir.
Prevention and control:
Not encountering this disease before observing the correct health and management principles, providing chickens from healthy flocks and hatchery factories free from contamination, which almost completely prevents the occurrence of this disease.
treatment :
Yolk sac infection or umbilical swelling disease by performing an antibiogram test and prescribing antibiotics can reduce losses and control the disease, but cured chickens can never grow as healthy chickens, so the author’s recommendation; Removal of infected chickens from the flock.
Providing rations, concentrates and specific micronutrients for broiler, egg-laying and mother birds
