Loss of appetite, respiratory difficulties, and nervous paralysis are symptoms of Newcastle disease in birds. Newcastle disease is a highly contagious viral infection that affects a wide range of bird species, including domestic poultry. The disease is characterized by respiratory signs, such as gasping, coughing, and nasal discharge, as well as digestive signs like diarrhea and a decrease in feed and water consumption. The nervous system can also be affected, leading to paralysis of the legs, wings, and neck. Newcastle disease can have a significant impact on the poultry industry and can result in high mortality rates in infected flocks.
