This study was conducted to determine the
effect of dietary supplementation with Tilia
tomentosa on the growth performance, digestive enzyme activity, haematological
indices and nonspecific immune indices of juvenile common carp (Cyprinus carpio). Fish with an average
weight of 4.35 ± 0.16 g were fed a diet supplemented with an aqueous methanolic
extract of T. tomentosa at a dose of 0% (control), 0.01%, 0.05% or 0.1% over
45 days. By the end of the study, the final weight, weight gain and specific growth rate were observed to be significantly higher for the 00.1% and 0.1% groups compared
with the control group (P < 0.05).
The feed conversion ratio was significantly decreased in the 0.05% and 0.1% groups compared with
the control (P < 0.05). The activities
of various digestive enzymes (amylase, lipase and trypsin) were also measured
and no significant differences were observed compared to the control (P > 0.05). The mean cell volume of the 0.01% group was significantly increased compared to the control
(P < 0.05) and increased lysozyme activity was observed in the 0.05%
and 0.1% groups. Respiratory burst activity was significantly increased (P < 0.05) on days 15 and 30 for the 0.1%
and 0.05% groups, respectively. No differences were observed for
myeloperoxidase activity among the four groups. These results suggest that
aqueous methanolic extract of T.
tomentosa has a growth-promoting and immunostimulatory effect on common carp.
