Key points of disease prevention and management in raising geese in spring

1. Gosling indigestion

The digestive organs of the goslings under 2 weeks old are not fully developed and the digestive function is weak. If the feeding management is not proper, it is easy to cause indigestion. For example, soon after the goslings came out of the shell, they were fed with a feed with high crude fiber content; suddenly changed the feed formula and feeding amount; and there were no fine sand grains in the feed, so that the digestive function of the muscle and stomach was poor. In addition, sudden changes in the weather and other factors can also easily lead to the occurrence of the disease.

1. General symptoms. The sick chicks are in low spirits, bow their heads and close their eyes, their feathers are dull, their wings are drooping, and their appetite is reduced or abolished. The stool is thin, the defecation frequency increases, shows the light green or white, sometimes has the foam or mucus, has the sour stink. There are filth and adhesion around the anus, and the sick chicks have poor growth and development.

two。 Prevention and control methods. The first is to improve feeding and management. Gosling feed should be nutritious, easy to digest, no corruption and deterioration, it is best to feed it now, not overnight feed. Feeding should be rationed at a fixed time. Seven days before the rearing period, mix the material with appropriate amount of warm water. The drinking water of the chicks should be replaced with lukewarm water. After 5 days of age, add an appropriate amount of fine sand to the feed. For goslings that have been sick, they can be fed with yeast tablets or milk enzyme, 0.2 grams per goose each time, and mixed for 2 days; for goslings with diarrhea symptoms, 0.04% of dysentery or 2% of charcoal shavings can be added to the feed and cured for 2 days.

2. Gosling plague

The disease is an acute and septic infectious disease of goslings. The diseased geese showed symptoms such as mental fatigue, waste food, dysentery and anal incontinence. Generally, it occurs after 3 to 5 days, which can spread to the whole flock, but not for geese after 1 month old. The typical pathological change is the formation of emboli in the small intestine, which can block the intestine in severe cases.

1. General symptoms. The disease can be divided into the most acute, acute and subacute. The most acute type: sudden death of unknown cause. Most of them occur in goslings within 1 week of age. Acute type: mostly occurred in 1-2-week-old goslings, mental distress, waste food, severe dysentery, discharge of yellow-white or yellowish-green stool, the course of disease was 1-2 days, and mental symptoms appeared before death. Subacute type: mostly occurs in geese more than 2 weeks old, poor spirit, do not eat, dysentery. Some geese heal themselves.

two。 Prevention and cure measures

Goslings were vaccinated with Gosling plague vaccine twice about one month before laying, so that the inoculated eggs contained maternal antibodies, so that the goslings were passively immunized. If the breeder goose is not vaccinated with Gosling plague vaccine, the Gosling Plague attenuated vaccine will be injected to the newly hatched goslings. If the breeder geese have been vaccinated, they can also be vaccinated according to the local epidemic situation. Gosling plague high immune serum should be used to control diseased geese and geese in the same group.

Goose influenza

Goose influenza, referred to as goose influenza, mainly occurs in goslings. Most of them are infected by the sudden change of climate, poor feeding and management, and the goslings are infected by cold. The mortality rate of the disease is high.

1. General symptoms. The sick goose shows mental malaise, loss of appetite, Gosling stacking, runny nose, difficulty breathing and shaking its head. When shaking its head, the nose sticks to the feather, which is dirty, damp and dishevelled. The course of the disease is usually 3-5 days, with severe dysentery before death.

two。 Prevention and control measures. Pay attention to keeping warm and scientific feeding and management of goslings within 1 month of age. The disease can be prevented by injection of inactivated vaccine in areas with frequent occurrence of the disease. The effect of oral sulfadiazine tablets is better when penicillin is injected intramuscularly in diseased geese. At the same time, attention should be paid to preventing cold and keeping warm and improving the conditions of feeding and management.
