What disease did the goose get when he defecated green and died quickly?

Ma Yonggen, Qinxing Village, Zhenze Town, Wujiang City, called to say that he raised more than 400 geese. When the geese weighed three or four jin, he found that several geese could not afford to lie down, excreted green feces, and died quickly. Six geese died in two days, and several geese also showed lying symptoms. The local veterinarian diagnosed a septic infectious disease.

According to the above situation, geese may have viral enteritis or avian cholera. Both diseases have symptoms of green feces and rapid death, which should be further diagnosed.

Goose viral ulcerative enteritis is an acute septic infectious disease caused by duck plague virus, which is characterized by high fever, tears, swelling of head and neck, ulceration of cloaca, green defecation and weakness of legs. At the beginning of the disease, the body temperature rose to 42-43 ℃, lethargy, loss of appetite, soft feet, unable to rise on the ground, and drooping wings. The characteristic symptoms are eyelid edema, tears, moist feathers around the eyes, conjunctival congestion and bleeding. Head and neck swelling, nostril outflow of a large amount of serous, mucinous secretions, dyspnea, often head up, cough. Diarrhea, yellow-green, gray-green or yellow-white loose stool, with blood in the feces. Anal edema, cloacal mucosa congestion, swelling, severe cloacal eversion. The penis of a sick goose cannot be recovered. When carrying the sick goose, the green, smelly and sticky liquid can flow out of the mouth. It usually takes 2 to 5 days to die, and some can prolong the course of disease. Most of the adult geese showed tears, diarrhea, lameness and the decrease of laying rate.

Diseased ducks, diseased geese and their carriers are the sources of infection of the disease, which can be transmitted through direct and indirect contact. Polluted water, feed, drinking water and utensils are all vectors of the disease. Diseased geese are infected mainly through digestive tract and respiratory tract, as well as through eye conjunctiva and blood-sucking insect bites. Naturally, infection occurs in close contact with infected ducks, first in ducks and then in geese. Geese of different ages, breeds and genders can get sick, but geese at the age of 15 to 50 days are highly susceptible, with a mortality rate of about 80%. The morbidity and mortality of adult geese vary with environmental conditions, generally about 10%, but in epidemic areas can be as high as 90% to 100%.

For the diseased geese, while taking measures of isolation and disinfection, duck plague vaccine was used for emergency vaccination. The diseased geese should be fed with more green feed and less granules, and oral rehydration salt should be used instead of drinking water for 4 to 5 days, and vitamins and antibiotics should be properly fed in the feed to enhance disease resistance and prevent secondary infection. For geese in threatened and epidemic areas, the attenuated duck plague vaccine was vaccinated with 15 times the dose of ducks for goslings under 15 days old, 20 times for 15-30-day-old goslings and 25-30 times for geese over 30 days old.

Avian cholera, also known as avian pasteurellosis or avian hemorrhagic septicemia, is an acute septic infectious disease in chickens, ducks and geese. It often contains a large number of bacteria in the feces and secretions of diseased geese, which pollutes feed, drinking water, utensils and sites, etc., leading to the disease of healthy geese.

Main symptoms: the most acute type has no obvious symptoms, often falls to the ground suddenly while eating or after eating, and dies quickly. Acute type, the course of disease 1-3 days death, manifested as mental fatigue, loose feathers, loss of appetite or abstinence, increased drinking water, often diarrhea, discharge of yellow, gray-white or light green thin feces, sometimes mixed with blood filaments or blood clots, smelly. Chronic type, mostly occurred in the later stage of the epidemic, diseased geese emaciated and anemia, leg joint swelling and suppuration, lameness, and finally emaciated and died. A few sick geese grow slowly even if they recover.

In the areas with frequent occurrence of the disease, aluminum hydroxide vaccine or attenuated live vaccine of avian cholera should be injected regularly. The general immunity period is 5-6 months, and the protection rate is 60%-70%. The commonly used therapeutic drugs are sulfonamides, antibiotics and so on.
