Rhinitis affects chicken production performance how to prevent and cure chicken rhinitis

Chicken rhinitis is a frequent and high disease that has plagued the chicken industry in our region in recent years, with a long course of disease and not easy to cure, which seriously affects the production performance of chickens. The main manifestations are thin or sticky nasal fluid, sneezing, coughing or gongs in the trachea, and severe swelling around the orbit. Infectious rhinitis is an acute respiratory disease of chickens caused by Haemophilus. The disease spreads rapidly, the incidence of non-immune chickens can be more than 70%, some even up to 100%, the course of the disease is long, often bring serious economic losses to the chicken industry.

Prevention:

1. The diseased chickens were isolated and treated, and the henhouse, floor and utensils were disinfected with 0.3% peracetic acid.

two。 Strengthen the feeding management, do a good job of cold protection and warmth of the chicken house, reasonably adjust the feeding density, feed full-price compound feed, ensure the supply of vitamins and trace elements, so as to enhance the disease resistance of chickens.

3. When the chicks grow to 40 days old, each chicken is injected with 0.3 ml rhinitis oil emulsion inactivated vaccine and 0.5 ml intramuscularly before laying, which can protect the whole laying period from rhinitis or rhinitis.

Prevention and control measures:

1. Sulfamethazine was mixed into the feed in the proportion of 0.2% for 3-4 days.

two。 Streptomycin was injected intramuscularly with 100-200 mg per chicken once a day for 3 days.

3. Oxytetracycline was mixed into the feed in the proportion of 0.2% and fed for 3-4 days.

4. At the same time of treatment, the effect of combined surgical therapy is better. For example, 2% boric acid water can be used to rinse the affected area when sick chickens show rhinitis and ophthalmitis; if bean curd-like coagulants accumulate in the sinus, they should be cut open with surgical blades, and all the coagulants should be clipped out with tweezers. After rinsing with boric acid water, drop penicillin eye drops.
