Gumboro is a viral disease found in chickens, usually between three and eight weeks of age. The disease does not cause sickness to other poultry and is easily spread from infected chickens to healthy chickens through food, water, and physical contact.[1]
Manifestations of the disease
Chickens infected with the disease generally have the following symptoms:
- Observed pecking at other chickens.
- High fever.
- Mood swings.
- Ruffled feathers.
- Trembling and slow walking.
- Often found lying together in clumps with their heads sunken towards the ground.
- Diarrhea, yellow and foamy stool, difficulty in excretion.
- Reduced or stop eating.
The mortality rate is around 20% with death within 3–4 days. Recovery for survivors takes about 7–8 days.
The presence of maternal antibody (antibody passed to the chick from the mother) changes the disease's progression. Especially dangerous strains of the virus with high mortality rates were first detected in Europe; these strains have not been detected in Australia[2].
Prevention
Firstly, it is necessary to implement well technical hygiene measures to prevent diseases, as well as biological safety.
Acquire breeding chickens from parents who have been fully vaccinated, further vaccinating when chickens are 5 days old and a second time the chickens are 15 days old.
When infected chickens are diagnosed, a Gumboro antibody injection may be administered. This is a drinkable mixture of electrolytes, vitamins, and medicine.
