The main points for the diagnosis of chicken disease
First, ask the so-called question, when the diagnosis and treatment of chicken disease, the diagnosis and treatment of people should first of all know the situation of the chicken population, such as breeders, administrators, technicians to ask in detail the age of their chickens, the number, species, Density, onset time, onset, clinical symptoms, death, necropsy, application, and treatment effects. Through inquiry, I have a general understanding and mastery of all aspects of the affected chickens for reference during further treatment. Second, listen to the so-called listening, refers to concentrate on hearing clearly whether the breath of chickens abnormal breathing tone, cough, sneezing, wheezing, strange call. In order to keep the flock quiet and listen to the birds, you should try to keep your movements light and slow as you enter the henhouse. Don't frighten the flock. Necessary fashion to go deep into the coop at night, let the chickens go to rest and listen. Third, the smell of the so-called olfactory, refers to the diagnosis of patients into the henhouse, with their own sense of smell, to understand whether the air in the chicken house glare, attack the nose, air squeezing depression, etc., to determine the gas in the house gas harmful gases Such as ammonia, hydrogen sulfide, carbon monoxide is too much, litter has no mildew, hen house humidity is too large or too small and other undesirable phenomena. 4. The hope is to visit in order to understand in detail the crown color and shape of chickens in chickens, the luster and growth of feathers, the behavior of chickens, the color and shape of feces, the conditions of eating and drinking, the mental state, and the nostrils. No secretions, eyes with or without tearing, swelling, nutritional status, house and environment clean, ventilation, light, wet and dry surfaces, temperature, chicken distribution. When necessary, pick up representative chickens for appearance inspections, such as elbows, skin color changes, etc. 5, the so-called cutaway, which refers to the necropsy, the purpose is to get through the necropsy chicken or dead chicken in order to obtain the naked eye can see the abnormal changes in various organs. At the time of the necropsy, as a veterinarian, it must be as specific as possible, and must not be sloppy or draw conclusions. Sometimes we must pay attention to the viscera process from the outside to the inside, and try to keep each organ intact, and strive to find typical representative lesions through necropsy. In addition, we should pay attention to as many as possible to examine some dead chickens, do not dissect one or two only. Six, inspection refers to laboratory tests. If the material obtained through questioning, listening, sniffing, hopes, and sectioning processes is still insufficient to determine what the disease is, if conditions are available, the disease should be promptly collected for laboratory testing to obtain a more robust diagnosis. in accordance with. In the collection of disease, we must pay attention to the disease should be fresh, no one for pollution, and save according to the method of preservation of the material requirements. In addition, you still need to provide laboratory inspectors with information that you have mastered and collected, and put forward recommendations and requirements for inspection projects for their reference, so that their purpose in the inspection is clearer. VII. Analysis The so-called analysis refers to analysis. A comprehensive and comprehensive analysis of the raw data obtained in the course of questioning, listening, sniffing, expectation, dissection, and examination is conducted to obtain the cause, incidence, epidemic area, and clinical symptoms of the diseased chicken flock. , necropsy lesions, laboratory test results, etc. have a clearer rationality, and compare and identify with similar diseases to determine what the disease is, is a disease or two diseases or multiple diseases, so that It has a clear direction and purpose when formulating preventive measures and applying medications. Eighth, so-called Shi Shi, that is, the application of treatment, the development of comprehensive prevention and control measures. This must be based on the information obtained in the process of “question, hearing, sniffing, hopefulness, dissection, and inspectionâ€. With “examination†as the premise, we must combine both organically and locally to formulate a solution to both the problem and the root cause. Set of practical treatment principles and comprehensive prevention measures. When selecting drugs, drugs with good efficacy, sensitivity to pathogens (and drug susceptibility testing if necessary), and rapid, low-cost, non-toxic or low toxicity (no toxic or side effects or low toxic and side effects) should be selected (Western medicine alone , can also be combined with Western medicine or pure Chinese herbal medicine), at the same time pay attention to environmental sanitation, cleaning and disinfection, adjust the temperature, humidity, ventilation, light, replace the litter, improve feeding management and feed nutrition, etc., in order to develop an ideal, scientific, comprehensive Possible comprehensive control measures. After it is implemented, the disease can be quickly controlled and extinguished, minimizing economic losses.
