Hen Diuresis Syndrome

Hen Diuresis Syndrome Overview


Hen diuresis syndrome is an emerging syndrome in the broiler breeding industry. It is associated with transient muscle weakness in the vent and diuresis, resulting in a condition referred to as 'pasty vent'. The syndrome is characterized by the presence of urate deposits on the skin of the chicken, just below the vent. The cause is unknown but is thought to be the result of a metabolic disturbance. Affected hens are often observed straining to lay an egg.
