Common diseases of geese

1 Infectious diseases

1.1 Gosling plague

It is an acute septic infectious disease of goslings. Suffering from the goose depressed spirit, loss of appetite, severe dysentery, and sometimes neurological symptoms. The disease mainly affects 4-and 20-day-old goslings. At the initial stage of the disease, loss of appetite, mental malaise, necking, fluffy feathers, solitude and difficulty in walking; then loss of appetite, severe dysentery, discharge of sparse feces mixed with air bubbles or yellowish-white or yellowish-green water; increase of nasal secretions, shaking of the head, fluid swinging out of the mouth, beak and webbed cyanosis.

Prevention is mainly disinfection. The breeding eggs were fumigated and disinfected with formalin. One month before laying, the goose was injected with 1 ∶ 10-fold diluted Gosling plague vaccine 1mL, or immunized serum as described. The immunization period was 300 days, once a year. Two weeks after injection, the goslings hatched by the breeding eggs laid by the goose had immunity.

1.2 Goose dysentery

It is an infectious disease caused by salmonella, and goslings are the most common. Sudden climate change, poor feeding and management, feed deterioration and so on are easy to induce the disease. The goose's beak is often surrounded by mucus, mental malaise, loose feathers, drooping head and eyes, loss of appetite or abstinence, and gradually weakening physique; serious illness often excretes undigested food, sometimes in the early morning, and dies in the afternoon.

Prevention is mainly not feeding corrupt feed, strengthening feeding management, paying attention to environmental hygiene, and often disinfecting goose houses and utensils. The effect of oxytetracycline, chloramphenicol or furazolidone is better after the disease. Garlic can also be washed and mashed, 1 part of garlic and 5 parts of water to make 20% garlic juice, the effect is better.

1.3 Gosling Influenza

The disease is an acute, septic infectious disease that occurs in large groups of farms, often affecting goslings after half a month of age, so it is called Gosling influenza. In the early stage, the goose's nose kept running, sometimes tears, shortness of breath, snoring, and even open mouth breathing; there was nasal mucus on the front feathers of the goose's body, and the body hair was moist; with the aggravation of the disease, the goose shrank its neck and closed its eyes, its body temperature rose, and its appetite gradually decreased. In the later stage, the head and feet trembled, the feet could not stand, and dysentery appeared before death. The mortality rate of goslings is generally 50% to 60%, sometimes as high as 90% to 100%. Prevention is the main treatment, and the feeding and management of geese should be strengthened to ensure the appropriate feeding density. Keep the goose house dry and the ground mat clean. For goslings within 1 month of age, attention should be paid to cold protection and warmth, and affected geese can be treated with chloramphenicol, sulfathiazole sodium or sulfadiazine.

2 parasitic diseases

Goose coccidiosis: this disease is a common poultry protoplasmosis, chickens, ducks, geese can be infected, the harm to young birds is particularly serious, the outbreak can cause a large number of deaths, acute patients die within 1-2 days after the disease. Most sick geese begin to shake their heads and food comes out of their mouths; foaming at the mouth, drooping head and neck, and unstable standing; diarrhea, bloody feces, reddish brown, loose cloaca, surrounding feathers contaminated by faeces; loss of appetite in the course of the disease, and then abandonment; mental fatigue, necking, wings drooping; sparse or red mucus in feces, and finally failure and death. Chloroguanidine 30mg/kg mixed with feed for 4 days can effectively prevent the outbreak of the disease. The treatment of dysentery can be cured by mixing 200~400mg/kg with feed or drinking water for 3 to 5 days. In addition, it can also be treated with amproline, coccidial net and so on.

3 common diseases of geese

3.1 soft foot disease of geese

It is mainly caused by lack of calcium, phosphorus and vitamin D in feed or long-term feeding of single feed. The disease mostly occurs in autumn and winter and in humid environment, and goslings are easy to occur. The goose feet are weak, often lying on the ground, growing slowly, the end of the long bone is enlarged, and the tarsal joint is osteoporotic. The prevention of the disease should be based on reasonable preparation of the content and proportion of calcium and phosphorus in the diet, adequate feeding of vitamin D, and cod liver oil and calcium tablets for treatment. Cod liver oil was fed twice a day with 2-4 drops per day, and vitamin D was given intramuscularly with 15000lu or intramuscular injection of 40, 000 Iu.

3.2 organophosphorus poisoning

Geese can be poisoned by accidentally eating vegetables, forage grasses or pond water contaminated with organophosphorus pesticides. The symptoms are sudden cessation of food, mental uneasiness and dyskinesia; obvious narrowing of pupils and tears; frequent shaking of the head and swallowing; muscle tremor; dysentery; dyspnea, hypothermia; and finally convulsion, coma and death.

Treatment: intravenous injection of propranolol 45mg/, or intramuscular injection of atropine sulfate. Each adult goose was injected with 22 mL of primaine for 20 minutes, followed by oral atropine every 0.5 hours for 3 times.
