Parakeets need a varied but balanced diet and plenty of water. Dehydration can kill your bird quickly, so always make sure there's water in her cage. Instead of buying a standard bird seed, look for a seed mix that is designed specifically for parakeets. These often contain dried fruit and other nutrition your bird needs, such as calcium -- low blood calcium can cause sudden death. Give her some small pieces of fresh, raw fruits and vegetables to help round out her diet. Don't leave fruit in her cage all the time, though.
Actinobacillus pleuropneumonia (APP) and Actinobacillus suis (AS) are bacterial infections of the lungs that cause sudden death in all ages of swine. Both organisms can cause numerous deaths at a single visit. With APP, it is common to see pigs that have recently died with blood coming from the nose.n general, sudden death in finishing pigs can be divided into enteric (gut) conditions, respiratory (lung) infections and individual pig events. Enteric conditions would include ileitis, hemorrhagic bowel syndrome (HBS), twisted gut and stomach ulcers.
