Hemorrhagic Proliferative Proventriculitis and Gizzard Erosion in Poultry Birds.

ABSTRACT

A new disease condition has emerged affecting replacement pullets. It affects the birdsbetween 2 to 10 weeks of age. The mortality rate varies between 1 to 10% and ultimately the flock is left with creation of several small poorly feathered and pale chicks. Though it has not been possible to establish the exact cause of this condition, following three points has been taken in consideration. HPPGE is an illness that involves one or more infectious agents. The digestive tract and endocrine organs may be primary targets for this agents.The spectrum of signs or lesions are either caused by or exacerbated by nutritional, husbandry and hygienic factors. The response to the treatment is often poor but the symptomatic treatment has helped in ameliorating the mortality. Similar condition has been widely reported in broilers under various names like Malabsorption syndrome, infectious Proventriculitis, infectious runting syndrome, pale bird syndrome and stunting syndrome.
