Abstract: The present study was conducted at the Indian Veterinary Research Institute in Izatnagar, Uttar Pradesh, to analyse the mortality trend in crossbred cattle and Murrah buffaloes. The relevant data for the current study was gathered from all traceable history sheets, livestock inventory registers, growth and milk registers, mortality registers, and other documents pertaining to crossbred cattle and Murrah buffaloes, over a 36-year period (1969-70 to 2003-04), from Cattle and Buffalo farm at Indian Veterinary Research Institute, Izatnagar, The main causes for mortality were disorders of digestive system (33.46%) followed by respiratory system (16.73%), specific infectious diseases (14.06%), unknown etiology (13.56%), other miscellaneous causes (13.44%), muscular-skeletal system (5.28%), urogenital system (2.32%) and diseases of circulatory system (1.25%,). In Murrah buffaloes, maximum deaths were due to digestive disorders (52.61%) followed by unknown etiology (15.40%) and other miscellaneous diseases (10.76%). In 0-1 month, age group, major cause was mortality was due to digestive system disorders in which higher mortality found in Murrah buffaloes (71.23) followed by 42.62% in HCG and 39.82% in HBC. Dairy owners are suffering significant financial losses as a result of the high herd mortality rate, which is a reflection of inadequate management. Hence, in any organised herd the mortality rate should be keep within the permissible limit to avoid the economic losses to the dairy farmers.
