Which symptoms are indicative of a respiratory infection in livestock?

• A. Coughing, nasal discharge, and fever
• B. Loss of appetite and lethargy
• C. Excessive thirst and urination
• D. Skin lesions and swelling

Answer: (A)

Coughing, nasal discharge, and fever are classic symptoms of a respiratory infection in livestock. These signs indicate that an animal's respiratory system is affected, often due to bacteria, viruses, or other pathogens. Coughing is a common response as the animal attempts to clear irritants or mucus from the airways, while nasal discharge can signify inflammation or infection in the nasal passages. Fever is a systemic response to infection, helping the animal fight off pathogens. When these specific symptoms are present together, they strongly suggest that the animal is battling a respiratory issue, making this choice the most accurate among the options provided. The other symptoms listed in the choices, while they may indicate health problems, are not primarily associated with respiratory infections. For example, loss of appetite and lethargy can occur with various medical conditions, including digestive issues. Excessive thirst and urination are often linked to metabolic problems like diabetes or kidney disease, and skin lesions or swelling typically indicate dermatological or systemic conditions rather than respiratory ones. These factors highlight why coughing, nasal discharge, and fever are key indicators of respiratory infection specifically.
