Prevention and treatment of Influenza in Gosling

The disease is a common acute, respiratory and septic infectious disease, which mainly occurs in winter and spring. Goslings of about 500 grams are the most susceptible to infection (adult geese are less likely to get sick), with a serious morbidity and mortality of 80% to 90%. Abrupt climate change, large temperature difference in goose house, long-distance transportation and poor feeding management can all lead to the occurrence of the disease. The disease is mainly transmitted by respiratory tract, and contaminated feed and drinking water can also spread the disease.

First, the main characteristics of symptomatic sick geese are dyspnea, a large number of serous secretions flow out of their nostrils, some have eye drops, sometimes snore, and even open their mouths to breathe, often shake their heads to shake off nasal mucus, and often bend back to wipe nose fluid on both sides of the front feathers of the body, making the feathers of the whole flock of goslings dirty and wet. The course of the disease is mostly 2-4 days, the seriously sick geese will develop dysentery, foot paralysis, unable to crouch on the ground, unable to stand, reluctantly standing will immediately overturn; mildly diseased geese can generally endure, will not die. There are obvious fibrous membrane hyperplasia in respiratory organs of diseased geese, hyperemia and bleeding in trachea and bronchus, translucent exudate in lumen, pulmonary blood stasis, bleeding spots in endocardium and epicardium, mild hepatomegaly and congestion. Gallbladder is enlarged and filled with bile; kidney stasis.

Prevention and treatment 1. Do a good job of cold protection and heat preservation of goslings at the age of 4-50 days, strictly prevent the temperature difference in the house from changing too much, and ensure that the temperature at the age of 5 days is 2728 ℃, the age of 10 days is 25 ℃, the age of 11 days is 22 days 24 ℃, the age of 16 days is 22 days 22 ℃, and the age of 21 days 30 days is 18 days 20 ℃.

two。 Keep the inside and outside of the goose house clean, ventilated and transparent, change cushions frequently, water fountains and lees are washed with 2% sodium hydroxide solution every day and washed with clean water to ensure the hygiene of drinking water every day.

3. When there is a sudden change in outdoor temperature, the goslings should not give up and graze, let alone go into the water. It must be noted that 40-50-day-old goslings had better not go into the water. At the same time, it is necessary to ensure the high quality and full price of the feed, rationally allocate the feed, and put 810% chicken feed and other concentrate into the green feed every day within the age of 30 days.

4. Each feather was subcutaneously injected with 0.5 ml of Haemophilus pure culture inactivated vaccine for 3 times at intervals of 5 days, or 1.5 ml was taken orally for the first time, followed by 0.5 ml after 5 days, which had a good preventive effect.

5. Twice daily intramuscular injection of penicillin 10,000-20,000 units / feather for 2 days, or twice daily intramuscular injection of streptomycin 1215 mg / feather for 2 days, or twice daily intramuscular injection of 30% analgesin nearly 2 ml for 3 days, has a very good therapeutic effect.

6. Take 0.2-0.3 grams of phthalein sulfonamide twice a day for 2 days, which has a good curative effect.

7. Mashed garlic and sugar water to take.

8. 500 grams of brown sugar and plantain, mixed with 7 kg of water, can be fed to 250 sick geese twice a day for 2 days.
