Differentiation of Pigeon Disease by "three looks and Nine checks"

In order to detect sick pigeons early and prevent the spread of the epidemic, breeders must carefully observe the flocks of pigeons in the morning, middle and evening every day. The method of "three looks and nine checks" introduced below to distinguish pigeon disease is simple and easy for reference. Three look: a look at the mental state: the healthy pigeon is lively, excited and sensitive; the sick pigeon is lethargic, lazy and slow to respond. Second, look at the diet: healthy pigeons eat and drink normally; sick pigeons eat less or waste food, do not think about drinking or binge drinking, and do not feed squab. Three look at the color and shape of feces: the feces of healthy pigeons are gray, yellowish brown or grayish black, in the shape of strips or spirals, and there are white attachments at the end of the faeces; the feces of sick pigeons are soft, rotten, green, foul smell and so on. Nine checks: check pigeon eyes: healthy pigeon eyes are bright, clean, alert and open wide. If there are secretions in the eyes, flushing or pallor of the conjunctiva, corneal opacity, dilated or dilated pupils are all symptoms. For example, ophthalmitis, paratyphoid, chronic respiratory diseases and vitamin A deficiency often make pigeon eyes inflamed, swollen, and secretions increased. Fever and conjunctivitis can make the conjunctiva red. Anemia or malnutrition can make the conjunctiva pale. Second, check the nose tumor: the nose tumor of healthy pigeon is bright, white and clean. Among them, the normal pigeon nose tumor was fleshy, and the child pigeon nose tumor gradually changed from flesh color to white. If the nose tumor is dirty and moist, and the color is dim, it is a manifestation of the disease. Especially when suffering from respiratory diseases, colds, paratyphoid and other diseases, the above performance is more obvious. Check the beak of pigeons: the beak of healthy pigeons is clean; the beaks of sick pigeons are often contaminated by increased nostril secretions. Four check breathing: healthy pigeons breathe evenly, 30 times / min-40 times / min; pigeons suffer from trichomoniasis, tracheitis, bronchitis, pneumonia and other diseases, runny nose, cough, asthma. When suffering from severe necrotizing pneumonia, it can be seen that the sick pigeon breathes with open mouth and the breath smells bad. Five check the mouth: open the mouth of pigeons, suffering from pharyngitis, diphtheria pigeon disease, mouth, throat flushing, ulcers or yellow-white false membrane. Vitamin A deficiency can be seen in the mouth of diseased pigeons with grayish-white nodules the size of corn grains. When suffering from soft crop disease, sour and smelly gas is exhaled from the mouth. Six check the crop: touch the crop with your fingers, if the crop is still swollen and solid 3 hours after eating, you may suffer from hard crop; if you don't eat, the crop is full, soft and fluctuating, and when you lift the pigeon upside down, there will be sour and smelly liquid in your mouth, and you may have soft crop disease. Seven check the anus: first observe whether the feathers around the anus are contaminated by feces, and then open the anus with your hands to see if the cloaca is congested or bleeding. Check the body: the healthy pigeon has a strong body and full chest muscles. Sick pigeons are generally thin and have no grip in their hands. At the same time, we should pay attention to check for sternal deformity and so on. Nine check the body temperature: use a thermometer to carefully insert the pigeon's cloaca for about 5 minutes to measure the body temperature. The normal body temperature of healthy pigeons is 40.5 ℃-42.5 ℃. More than 42.5 ℃ is a sign of fever, but sometimes after strenuous exercise or sunlight exposure, the body temperature will increase by 0.5 ℃.
