Abstract
The pathology of ascites syndrome in 55 male and female broiler chickens aged 26 to 44 days was studied and compared with normal controls. At necropsy, gross changes included dark breast muscle, marked abdominal distention, presence of 40-260 ml clear yellow fluid with clots of fibrin in the abdominal cavity, hydropericardium, cardiomegaly and pericardial haemorrhages, and congestion in lungs, liver, kidneys and intestines. The liver was shrunken with greyish capsule. The histopathology revealed congestion, dilatation of parabronchi and adjacent air capillaries, hypertrophy of smooth muscle of parabronchial walls, numerous small-to-large hyaline cartilaginous foci and, in some cases, osseous foci in parenchyma of lung. Congestion, oedema and myofiber degeneration of heart, pronounced dilatation of sinusoids, atrophy and degeneration of hepatocytes, marked thickening of capsule and in some cases fatty change of liver; congestion of glomeruli and urate deposits in the lumina of collecting tubules in the kidney; congestion, disappearance of white pulp and mild to severe thickening of capsule in the spleen, congestion, follicular depletion, intrafollicular cyst formation in the bursa of Fabricius were also seen.
