The present study was undertaken to investigate the changes in body weight, body measurements, reproductive parameters, hemato biochemical variables, faecal parasitic load and incidence of disease rate in black Bengal female goats (n= 60) managed under extensive, semi-intensive and intensive system for evaluating the sustainability and economic viability. The partial budget analysis was done to determine the profitability of farming among the 3 different management systems. The result showed a significant improvement (p< 0.05) in physical parameters like body weight (kg), height at wither (cm), heart girth (cm), early attainment of puberty with a higher rate (p< 0.05) of prolificacy and kidding among the goats managed under an extensive system of management. The percentage of PCV, plasma glucose and total protein level was found significantly higher (p< 0.05) in goats of intensive system but the cholesterol level was found more in goats of extensive system of management. The outdoor high humidity and temperate has affected the incidence of parasitic infestation and also the occurrence of diseases like diarrhoea and mastitis among the goats of an extensive system. However, the assessment of economic budget analysis showed a good net profit return from goats reared under extensive system compared to the other systems of management. Overall, the present study suggested that black Bengal goat rearing under the extensive system is a better choice for providing a substantial source of income to farmers with low budget input.
