Poultry Judging Practice Test

A disease with major symptoms of depression, coughing, sneezing, rales, edema, cyanosis, and diarrhea would be ______________.

1. Fowl Cholera

2. Avian Influenza

3. Chronic Respiratory Disease

4. Infectious Bronchitis

The correct answer is: Avian Influenza

Avian Influenza is characterized by a range of severe clinical signs, including depression, coughing, sneezing, rales (abnormal lung sounds), edema (swelling), cyanosis (bluish discoloration of the skin due to lack of oxygen), and diarrhea. These symptoms indicate significant respiratory and systemic distress, which aligns well with the pathogenicity of Avian Influenza, particularly in more virulent strains that affect various types of birds. The presence of respiratory symptoms such as coughing and sneezing, in conjunction with systemic signs like depression and cyanosis, suggests a viral infection that can rapidly infect and spread among domestic and wild bird populations. The disease can also lead to high mortality rates, especially in young birds, making it critical for diagnosis and management in poultry health programs. In contrast, conditions such as Fowl Cholera and Chronic Respiratory Disease may present with some overlapping symptoms, but they do not typically manifest all the severe clinical signs listed. Infectious Bronchitis shares some symptoms with Avian Influenza, particularly respiratory signs, but would not usually present cyanosis or diarrhea as prominent features.
