A 63-days indoor feeding trial was conducted to assess the growth performance of Labeo rohita fingerling (69.82±0.53
g) fed with three experimental diets containing black thorn, Kaempferia galanga as natural attractant, yeast as probiotic and
their combination. Comparable feed consumption in groups fed with attractant (86.54 g) and combination of attractant and
probiotic (85.17 g) compared to group fed probiotic only (74.10 g) were observed. Combined use of attractant and probiotic in
the diet resulted in highest percent live weight gain (105.30%) compared to the individual inclusion of attractant (60.88%) and
probiotic (72.63%). Comparison of feed conversion ratio (FCR) indicated better conversion when fed with the diet containing
both the attractant and probiotic (3.69) compared to the other diets containing either probiotic (4.96) or attractant (5.20).
Further, highest accretion of carcass protein was recorded in groups fed diet with combination of additives (254.79%),
followed by attractant (193.03%) and probiotic (159.29%) alone. RNA/DNA ratio in both liver and muscle exhibited a
significant (P<0.05), linear increase in groups fed diet with only probiotics followed by attractant alone, and the combination
of both probiotics and attractant accordingly. Present study revealed better efficacy of feed supplemented with Kaempferia
galanga in feed consumption, growth promotion and utilization in L. rohita fingerlings, as compared to that with probiotic.
However, the combination of probiotics and attractant could confer the better results as compared to their individual dietary
inclusion.
