This is broiler chicken, 19 days old, high mortality, with ulcer dermatitis (bacterial infection, Staphylococcus), nor respiratory symptoms. Chickens with symptoms of dermatitis are found only in one strain type of chicken, not found in other strains with the same litter origin.
Death of chicken with clinical symptoms, weakness, dull feather, daily mortality slightly increased from day 8. Only occurs in one strain of chicken, dead chickens and sick chicken found in every pen in the chicken house. This case is not found in another house with different chicken strains. On the 10th day began to see many chickens died with dermatitis symptoms.
there are haemorrages similar to gumboro virus infections (IBD) and IBH.
This farm often has gumboro cases. But in this production cycle, ulceration dermatitis becomes the most dominant symptom.
