Ascites (Water Belly) in Poultry: Causes, Prevention and Treatment
When a broiler suddenly becomes weak, struggles to breathe, or develops an enlarged abdomen, many farmers immediately suspect an infection. But sometimes the problem is ascites, commonly called water belly. Ascites is a condition in which excess fluid accumulates in the abdominal cavity. It is particularly associated with rapidly growing broilers and can lead to poor performance and mortality when severe. Understanding the causes can help farmers reduce the risk. What Causes Ascites in Chickens? Ascites is closely linked to increased pressure on the heart and lungs. When the bird's oxygen demand exceeds what its cardiopulmonary system can adequately supply, pressure can build in the pulmonary circulation, eventually causing fluid to accumulate in the abdomen. Several factors can contribute: • Rapid growth and high metabolic demand. • Poor ventilation and inadequate oxygen supply. • Cold stress, particularly during brooding. • High altitude, where oxygen ava...
