The
incorporation of garlic meal (GM) in diets for European seabass juveniles were
evaluated with a diet containing 43% protein and 17% lipid (gross energy 19kJ/g
diet). Experimental diets with GM incorporation of 0, 2, 4, and 6% were fed to
fish (10.60 ±0.16 g) until satiation for 60-days. Significant differences (p<0.05) were recorded for growth
performance, with the highest rate in the 4% GM group, followed by the control
group. Improved feed conversion (FCR) and protein efficiency rates (PER) were
observed in the GM4 group compared to the other treatments. Nitrogen retention
as a percent of intake was highest in the in GM4 group. Significantly higher
values (p<0.05) were found for
body protein and lipid, and lower values (p<0.05)
for the hepatosomatic, viscerasomatic or mesenteric fat indexes in the GM4
group compared to the other treatments. Fish fed garlic supplemented diets
showed lower saturated fatty acids (SFA) and monounsaturated fatty acids
(MUFA), but higher polyunsaturated fatty acids (PUFA) compared to the control
group with no garlic treatment. Results indicate that dietary GM inclusion of
4% can improve fish growth and nutrient utilization with an increase of fish
muscle quality by elevated PUFA concentrations, and a reduction of total
nitrogen excretion.
