    Studies on Pancreatic Pathology and Its Correlation with Different Wasting Disease Conditions of Poultry
    (Birsa Agricultural University, Ranchi, 2019) KUMAR, BRAJESH; Gupta, M. K.
    3796) birds examined showed definite pancreatic pathology. Maximum incidence of pancreatic pathology was observed in fungal (83.33%) and metabolic (82.86%) diseases whereas least pancreatic pathology was registered in viral diseases (16.41%). The overall incidence of pancreatic pathology in viral disease other than RD has been observed to be 66.95%. Disease wise incidence of pancreatic involvement is significantly higher in cases of IBD (94.74%) followed by IB (93.33%) and pasteurellosis (90.48%). Contrary to rest of the viral diseases the pancreatic pathology was extremely low (13.61%) due to RD though mortality of birds registered was highest, followed by pneumonia of bacterial origin ( 16.58% ). Incidence of pancreatic pathology in different poultry varieties showed that broiler birds were most susceptible (75.34%) to develop pancreatic pathology whereas Vanraja (14.29) variety showed significantly low susceptibility. Age group wise maximum pancreatic pathology was registered in grower birds (33.69%) followed by chicks (20.06%) and adult birds (19.54%). A significant variation was also observed in susceptibility to increased pancreatic pathology under different disease conditions between the three age groups. It was observed that highest percentage of pancreatic pathology was observed in monsoon season (28.84%) followed by summer (22.57%) and least was observed in winter season (12.92%). Though the incidence of pancreatic pathology was less in summer season the percentage of pancreatic involvement was significantly higher for most of the disease conditions.
