Traditional Chinese medicine treatment for infectious bursal disease in chickens with reduced feed intake, increased water intake and dehydration
Infectious bursal disease in chickens, also known as infectious cloacal bursa disease in chickens, is an acute and highly contagious disease caused by infectious bursal disease virus. The disease has a sudden onset, a short course and a high mortality rate, and it can suppress the chicken's immunity. It is characterized by inflammation, atrophy and necrosis of the bursa of Fabricius and severe damage to lymphocytes in the bursa of Fabricius, thereby causing immune dysfunction in chickens and interfering with the immune effect of vaccines. The incidence rate is high, reaching almost 100%, while the mortality rate is low, generally 5%-15%.
Chickens
Symptoms:
A flock of chicks suddenly develops the disease in large numbers, and within 2-3 days 60%-70% of the chickens are affected. Three to four days after onset, deaths peak, and after 7-8 days deaths stop. At the beginning of the disease, the chickens are depressed, with reduced feed intake and increased water intake; some peck at their own vents and pass white watery diarrhea. In severe cases, they become dehydrated, lie on the ground unable to stand, are extremely weak, and finally die. Chicks that do not die are anemic and emaciated and grow slowly.
Necropsy changes:
The bursa of Fabricius shows yellow gelatinous edema, is hard in texture, and its mucosa is covered with cream-colored fibrinous exudate. Sometimes the mucosa of the bursa of Fabricius is severely inflamed, with hemorrhage, necrosis and atrophy. In addition, dead chickens show dehydration, and the muscles of the legs and chest often hemorrhage and are dark red in color. The kidneys are swollen, and the renal tubules and ureters are filled with white urates. The spleen and the mucosa at the junction of the proventriculus and gizzard hemorrhage.
