Abstract: The effect of herb supplemented diet on growth, metabolism and Haemato-immunological parameters of an Indian Major Carp, Labeo rohita fingerlings was studied. Fishes were fed with a diet containing four graded levels (0.0, 0.06, 0.08 and 0.1 g/100g diet) of herbal combination of Mucuna pruriens and Pedalium murex (1:1). The supplemented diet significantly (p<0.05) improved the growth, specific growth rate (SGR) and food conversion ratio (FCR) as compared to control. Still the highest weight gain and specific growth rate (SGR) were recorded with 0.06g per 100g herbal supplemented diet. The increase in digestive enzymes like protease, amylase and lipase supported the results of increased growth at treatment level 0.06g/100. The levels of metabolic enzymes (i.e. LDH and MDH) in lever and muscles were significantly (p<0.05) decreased in treatments as compared to control. However, the enzymes of protein metabolism were significantly (p<0.05) increased in comparison to control. Similarly haematological parameters such as packed cell volume (PCV), haemoglobin content (Hb) and erythrocytes (RBC) were significantly (p<0.05) different in treatments and control. A significant (p<0.05) proliferation of the leukocytes (WBC) was recorded in herbal supplemented diet. The results of this study proved a significant role of herbal combination of Mucuna pruriens and Pedalium murex on growth, metabolism and immune defence mechanism of Labeo rohita fingerlings.
