Aim: Stevia is a
natural sweetener but is not readily metabolized or fermentable in animals.
It may have potential as a feed attractant; however, there is limited
information on the effects of dietary Stevia in fish.
Methodology: A 76-day-study
was performed to assess the growth, feed intake, body indices, muscle
proximate composition and intestinal short chain fatty acids (SCFA) in red
hybrid tilapia fed with increasing Stevia (steviol glycosides) at 0, 1, 3 and
6%. A second experiment was performed to determine any changes in plasma
glucose, cholesterol or triglyceride levels in red hybrid tilapia at 1, 3, 6,
12 and 24 hr after being fed 0 or 6% Stevia.
Results: In experiment 1,
dietary Stevia had no significant effect (p > 0.05) on any of the measured
parameters in tilapia and in experiment 2, dietary Stevia had no significant
effect (p > 0.05) on the tested plasma biochemistry.
Interpretation: These findings
indicate that Stevia did not improve diet palatability to tilapia, as well as
not being metabolized for energy or fermented. Based on these findings,
there is no advantage to including Stevia at the tested levels in the diets
