Ascites
- 1.
- 2. ASCITES • The pulmonaryhypertension syndrome (PHS)or ascitis is related to the rapid growth and enhanced metabolic processes in broilers. • Affected chickens are with a strongly distended abdomen,reluctance to move, respiratory troubles and cyanosis. • Ascites occurs in mostly 5-7 week old broiler • Affects mainly in males
- 3. ASCITES • Ascites isa symptoms commonly noticed as BPHS (Broiler Pulmonary Hypertension Syndrome) • High altitude disease • Oedema disease • Heart failure syndrome
- 4.
- 5. ASCITES • The pleuroperitoneaIcavity of affected chickens is filled with straw-yellow fluid . • The rapid growth in contemporary broilers is related to higher needs for oxygen, and the lung remains relatively small vs body dimensions.
- 6.
- 7. ASCITES • Immediate causesfor hypoxaemia are the inadequate ventilation, the high ammonia or dust levels in premises, low temperatures, stimulating the metabolic processes. • Generalized passive venous hyperaemia and stasis in the liver and other viscera are observed.
- 8.
- 9. ASCITES • The posteriorvena cava and the right half of theheart are overfilled with blood.The stasis is sometimes causing liver rupture and internal bleeding.
- 10. Symptoms Water belly Abdominal distension Reluctant(unwilling) to move Dyspenic (labored breathing) Cyanotic (discoloration) lesions can be seen Listless (lacking energy) Ruffled feathers Mortality range – 20% of the flock
- 11. ASCITES • The mainfactor for PH is hypoxaemia that results in enhanced cardiac activity. • The consequences are pulmonary hypertension,right cardiac failure and leads to ascitis.

- 13. PM lesions Water belly(straw coloured fluid in abdominal cavity) Swollen liver Enlargement of right side of the heart Congested and blood clots in lungs
- 14. TREATMENT Adequate temperature controlof the house, good air and litter management. Vitamin C (500 ppm) has been reported to be of benefit Practice mash feeding instead of pellets
