Abstract

Ketosis is the common disease and one among the important metabolic disorder in lactating dairy animals. It is a condition marked by increased levels of circulating ketone bodies with or without the presence of the clinical signs. It causes severe economic losses through reduction in milk yield. For the study, 30 ketosis 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 ketosis in dairy farms. The estimated regression coefficient of three variables viz., order of lactation, season summer and number of days illness included to explain the variations in the losses due to ketosis were found to be significant at one per cent level (P≤0.01) and the other factors such as season winter and milk yield were found to be significant at five per cent level (P≤0.05).
