Clinical Laboratory Epidemiological Investigation of hemorrhagic Proventriculitis and Gizzard Erosion in Nepal

Le résumé fourni par la source

A new disease condition has emerged affecting replacement pullets and broiler chickens between 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. Hemorrhagic Proliferative Proventriculitis and Gizzard Erosion is an illness that involves one or more infectious agents. One the cause suspected for it is mycotic origin. 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 with toxin binder like toxolivum liquid, hepatocare, along with immunomodulaters like immunocare, and promin has significantly 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. Same condition is likely to be emerging as a problem for commercial broiler after 3rd week age.
