What are the common diseases of domestic geese? How to prevent and cure it?

Goose, breeding cycle is short, feed on grass and fodder, disease resistance is strong, extensive management, risk is small, is a good breeding project. But there are always diseases. What are the common diseases of geese in that family? How to prevent it? Let's find out below!

1. Goose plague

The disease is an acute, septic infection of goslings. The sick goose showed symptoms such as mental paralysis, waste food, diarrhea and ataxia. Disalt hatching occurs 3-5 days after hatching and can spread to the whole flock. Generally, geese after 1 month old do not occur. Typical pathological changes are intestinal emboli that clog the intestine.

Symptoms: The disease can be divided into the most acute, acute and subacute three types of disease. (1)Most acute: sudden death of unknown cause. It occurs mostly in goslings less than one week old. (2)Acute type has mental collapse, waste food, severe diarrhea, discharge of yellow-white or yellow-green water stool and other phenomena, the course of disease more than 1-2 days, nervous symptoms before death, mostly occurred in 1-2 weeks old gosling. (3)Subacute type: occur in more than 2 weeks of geese, there are poor spirit, do not eat, diarrhea water stool and other phenomena. Some geese heal themselves.

(2) Pathological changes: The main pathological changes were in the small intestine. The most acute goose died of sepsis such as intestinal mucosa congestion and hemorrhage. In geese that died of acute or subacute type, there was a large amount of exudate forming a band-like pseudomembrane in the small intestine, which was a embolus-like tube blocking the posterior part of the small intestine and making the posterior part of the small intestine like a sausage.

(3) Control measures: (1) Goose plague vaccine was used twice about one month before egg laying, so that eggs contained maternal antibodies, thus making goslings produce passive immunity. (2)If the breeding goose has not been injected with gosling plague vaccine, the newly hatched gosling should be injected with attenuated vaccine. For breeding geese that have been vaccinated, attenuated vaccine shall be injected as appropriate according to the local epidemic situation. (3)Goose disease and the same flock of geese to use high immunity anti-gosling plague serum for prevention and control.

II. Avian cholera

Avian cholera is an acute, septic disease of poultry, also known as sepsis. It's Pasteurella avium, and geese are easy to get. Most of them occur in autumn when geese are sexually mature. If preventive measures are not appropriate, they will occur every year in epidemic areas.

Symptoms: The disease is divided into the most acute, acute and chronic three types. (1)The most acute type: sudden death of unknown causes in the early epidemic. (2)Acute type: sick goose closed his eyes, did not dare to enter the water, increased drinking water, listlessness, appetite waste, diarrhea like grass green, body temperature in 41-43℃, course of 2-3 days, soon died. (3)Chronic type: occur in the late epidemic of the disease, goose only thin, diarrhea, arthritis symptoms.

(2) Pathological changes: The most acute lesions are not obvious. Acute type, chronic type epicardium, coronary sulcus bleeding point, intestinal congestion, bleeding.

(3) Prevention and control measures: (1) The epidemic area should be thoroughly disinfected before the epidemic, so as to avoid the recurrence of the disease as much as possible. (2)Timely treatment of epidemic diseases found. Sulfonamides, olaquindox and antibiotics have good effects. Generally, 0.02% compound sulfamethoxazole mixed with feed, and then penicillin, streptomycin mixture intramuscular injection for 3-4 days, twice a day can basically control the disease.

III. Goose influenza

Goose influenza, referred to as goose influenza, mainly occurs in goslings. Mostly because of sudden changes in climate, poor breeding management, gosling cold and infection. Performance for respiratory symptoms, because gosling disease resistance is poor, so the mortality rate is high.

(I) Symptoms: The sick goose is characterized by listlessness, loss of appetite, gosling piling up, runny nose, difficulty breathing and shaking its head. When it shakes its head, its nose sticks to its feathers, and its feathers will be dirty and untidy. The course of disease is generally 3-5 days. Severe diarrhea occurs before death.

(2) Pathological changes: subcutaneous and muscle hemorrhage, translucent exudate in upper respiratory tract, pulmonary congestion, epicardium hemorrhage, liver, spleen and kidney congestion or enlargement, common grayish yellow necrosis points.

(3) Control measures: (1) Keep warm and scientifically feed and manage goslings within one month of age. (2)Inactivated vaccine can be injected to prevent the disease. (3)The effect of intramuscular injection of penicillin and oral sulfadiazine tablets on sick geese is better. Meanwhile, attention should be paid to keeping warm and improving feeding and management conditions.

IV. Paratyphoid fever

Paratyphoid fever in geese is caused by Salmonella and occurs mostly in goslings. This is often caused by poor management. The main symptoms were diarrhea, conjunctivitis and emaciation, but the symptoms of adult geese were not obvious.

(1) Symptoms: The sick goose is mainly manifested as diarrhea, feces such as water, and the goose is becoming weaker and weaker. Goose loss of appetite, diarrhea, fecal contamination of the hind body, ten dry after the closure of the anus, resulting in defecation difficulties. Adult geese are chronic, mainly emaciated.

(2) Pathological changes: empty esophagus, hepatomegaly, congestion, mucosal congestion, hemorrhage, cloudy air sac membrane, cecum swelling, contents were cheese-like.

(3) Prevention and control measures: (1) Pay attention to feeding management, do not feed corrupt feed, breed geese with chronic diseases should be eliminated, disinfection should be paid to breeding eggs from hatching in frequently occurring areas, and feeding management should be strengthened for young geese. (2)Drinking water and mixing materials with enemy bacteria are effective.

V. LEPTOTAENSIS OF GOOSE

When the worms grow up, they accumulate in large quantities in the small intestine, which will cause mechanical blockage of the intestine, affect the digestion and absorption of geese, thus affecting the growth of geese and even cause death. Exotic varieties are more susceptible to the disease.

(1) Symptoms: growth retardation, anemia, diarrhea, emaciation, isolation, sporadic death of sick geese.

(2) Pathological changes: A large number of worms can be found in the small intestine of dead or sick geese. The insect body is milky white, flat, segmented, and lank-shaped in appearance. The adult is 8-15 cm long and 18-20 mm wide.

(3) Control measures: (1) Goose flock regularly dewormed. Adult geese in spring and autumn each year, once deworming, timely cleaning of feces, feeding water plants to be cleaned. (2)Strengthen feeding management and improve goose disease resistance. (3)The effect of oral anti-worm is better in sick geese. The dose of 20 mg/kg body weight is given once.

VI. Goose lice

Goose lice are parasites that hide in goose feathers. The worm is small and shaped like a tick on a cow. The lice live their entire lives on geese.

(1) Symptoms: lice suck blood, feathers and dander, and also hurt the skin, causing itching and restlessness in geese, causing slow growth and development of geese, emaciation, and reduced egg production in adult geese.

(2) Prevention and control measures: (1) Goose houses should be cleaned frequently and grass mats should be changed frequently. Goose houses are often disinfected by spraying with 0.2% dichlorvos. (2)has

Goose with goose lice can be sprayed with 0.5% trichlorfon powder in feathers.
