Milk fever is the common disease and one among the important metabolic disorder in lactating dairy animals. It is an afebrile hypocalcaemic disease of cattle usually associated with immediately after parturition and initiation of lactation. Milk fever is a metabolic disease occurring in dairy animals during parturient period and management is economically most important, as it results in not only reduction in milk production but also loss of animals. For the study, 83 milk fever affected dairy animals (both cows and buffaloes) were selected through multistage random sampling technique from Namakkal and Karur districts of Tamil Nadu. Data were collected from the respondent farmers through personal interviews, using pretested interview schedule. A multiple linear regression function model was fitted to study the factors influencing economic loss due to milk fever in dairy farms. The variables viz., late stage of lactation, season summer, season winter, number of days illness and milk yield included to explain the variations in the losses due to milk fever were found to be significant at one per cent level (P≤0.01). The other factor mid stage of lactation was found to be significant and negative at five per cent level (P≤0.05). The coefficient of average daily milk yield per animal (5.703) indicated that the economic loss due to milk fever would increase by Rs.5.703 per affected animal as the average daily milk yield of the animal increases by one litre of milk from its mean level.
