Abstract
The purpose of the present study was to evaluate the effects of dietary piperine on haemato-immunological parameters, growth profile and disease resistance in Indian major carp, Labeo rohita challenged with Aeromonas hydrophila. Fish were fed with a diet containing 0 g kg-1 (T0), 0.5 g kg-1 (T1), 1.0 g kg-1 (T2), 2.0 g kg-1(T3), 4 g kg-1(T4), and 8 g kg-1 (T5) of piperine and blood of the experimental fish was collected on 14th, 28th, and 42nd for evaluation of haemato-immunological profiles and fishes were challenged with A. hydrophila. Haemato-immunological parameters at the end of 42nd day trial revealed that piperine administered through feed significantly (P<0.05) enhanced the complete blood counts, haemoglobin level, respiratory burst activity, lysozyme activity, and phagocytic activity. The percentage weight gain, feed conversion ratio and protein efficiency ratio of fishes fed with piperine were found to be significantly (P>< 0.05) high compared with control. Dietary inclusion of piperine showed significantly (P<0.05) higher RPS in T3 (57.15%). The results reveal><0.05) higher RPS in T3 (57.15%). The results reveal that 2 g kg-1 piperine supplemented diet has a stimulatory effect on haemato-immunological parameters along with improved growth performance and increased resistance against A. hydrophila infection in L. rohita.
