Chicken infectious laryngotracheitis referred to as chicken throat, is a virus-caused acute respiratory infectious disease in winter and spring. Its clinical manifestations are dyspnea of ​​the diseased chicken, usually accompanied by loud wheezing sounds and coughing sounds. In severe cases, the mouth is stretched, the neck is breathed, the head is shaken, sometimes the coughing out of the exudate with blood, and the nasal secretion is increased. The necropsy showed that there were foamy mucus in the mouth and throat. Some yellowish coagulated masses adhered to the mucosa around the throat of the diseased chicken. The throat and tracheal mucosa were swollen and bleeding and formed erosion. Based on years of experience, the author summarizes the following therapeutic prescriptions for your reference.
(1) 5 to 8 attenuated virus attenuated strains of Newcastle disease VI or 3 to 5 attenuated virus vaccines of strain I of each guinea pig. At the same time, the attenuated laryngotracheitis attenuated virus seedlings were used for eyeballs, and 2 pigs per feather were spotted for every 500 feathers. The amount of vaccine used was 1 gram of ampicillin sodium sterile powder for injection. (2) Based on (1), add 15 to 20 grams of aminophylline per 100 kilograms of water (or 2.5 milligrams of ephedrine per kilogram of body weight per day), 5 to 10 grams of doxycycline hydrochloride and neomycin sulfate. The dosage is mixed for free use by the flock and can also be used together with the finished drugs for the treatment of infectious laryngotracheitis, such as throat kangkang and laryngectomy.
Infectious laryngotracheitis vaccination is best done twice, and it is advisable to perform each of the chickens 35 to 45 days old and 70 to 90 days old. In the course of immunization or treatment, if the use of infectious laryngotracheitis attenuated vaccine eye (non-instillation of nose) cause chicken swollen eyes, tearing or other respiratory diseases, are considered immune or emergency inoculation failure, should use antibiotics (such as hydrochloric acid Doxycycline, neomycin sulfate, or finished drugs for specific infectious laryngotracheitis produced by various veterinary pharmaceutical factories) to control secondary or concurrent infections (for 3 consecutive days), and at the same time, to inoculate once again attenuated laryngotracheitis attenuated vaccine .
