Predisposing Factors
Things farmers do to facilitate the occurrence of gumboro disease include, poor vaccination programme, inadequate supply of heat/warmth in the brooder, poor sanitation, presence of rodents and poor biosecurity.
Clinical Signs
Elevated body temperature, watery urate diarrhoea, ruffled feathers, trembling, huddling, depression, sleepiness and lameness can occur.
Postmortem lesions
The bursal is enlarged (2-4times), haemorrhagic and oedomatous.
Swollen necrotic spleen
Mucous in the intestines
Muscle haemorrhage, rickets and dehydration.
Haemorrhage at the Junction of the proventriculus and gizzard.
How To Control Gumboro Disease
Proper vaccination, biosecurity and provision of right temperatures in the brooder.
Treatment
There’s no specific treatment available but supplementing with glucose, vitamins and facilitating access to water, feeds and heat will help and more so enforcement of biosecurity.
Diagnosis
Oedematous involvement of the bursal of fabricius
Note
Gumboro disease is acute and highly contagious and can kill 30% to 100% of the flock if poorly managed
