Abstract
It is common nowadays to use natural food additives to increase the fish
growth, activity and immunity.
The aim of this study was to investigate the influence of dietary
supplementation of ginger, Saccharomyces or combination of ginger and
Saccharomyces for 30 days on weight, hematological, biochemical and
immunological parameters of African sharptooth catfish Clarias gariepinus.
The results indicated that, ration containing ginger only lead to significant
decrease in fish weight. But ration containing Saccharomyces only or
combination of ginger and Saccharomyces lead to significant increase in fish
weight.
Also the present findings indicated that, ration containing ginger, and/or
Saccharomyces showed a significant increase in the level of all tested
hematological and immunological parameters during the most of experiment
when compared with the control.
Spectrophotometric analysis revealed a significant increase in serum total
protein and globulins in fish fed ration containing ginger or combination of
ginger and Saccharomyces. But there is insignificant increase in total protein
and globulins in fish fed ration containing Saccharomyces only. Also there is
insignificant increase in albumin in all fish groups in comparison to control.
There were significant increase in phagocytic activity and index in all fish
groups in comparison to control.
Challenge of the fish groups with V. vulnificus, indicated that there were
significant decrease in cumulative mortality percentage in all fish groups in
comparison to control.
