Effect of zeolite (in feed) on growth performances of red tilapia (Oreochromis sp.)
The effect of zeolite added in diet of Oreochromis sp. was investigated in the present study. Zeolite was added in the diet at varying level, 0% (T1), 0.5% (T2), 1.0% (T3) and 1.5% (T4) and fed to fish for 12 weeks. Growth performance of the Oreochromis sp. was observed in term of weight gain, bo...

| Summary: | The effect of zeolite added in diet of Oreochromis sp. was investigated in the
present study. Zeolite was added in the diet at varying level, 0% (T1), 0.5% (T2),
1.0% (T3) and 1.5% (T4) and fed to fish for 12 weeks. Growth performance of the
Oreochromis sp. was observed in term of weight gain, body length, specific
growth rate, food conversion ratio and survival rate. Proximate analyses were also
conducted at the end of the study to compare the body composition of the fish
among treatments. The results of the study showed that the average body weights
of fish in the treatments T1, T2, T3 and T4 were 40.36±17.51 g, 34.09±16.78 g,
40.07±18.61 g, 38.66±18.42 g respectively and similarly average total lengths
were 12.44±1.82 cm, 12.12±2.63 cm, 12.57±2.30 cm, 12.37±2.29 cm
respectively. However, there was no statistical difference among treatments for all
parameters of growth performance (P>0.05). The body composition showed there
were statistical different (P<0.05) on protein, lipid and ash among treatments. T1
(55.68±1.44%) showed the highest percentage of protein followed by T3
(55.46±0.77%), T4 (55.19±1.12%) and T2 (53.31±0.7%). Thus, this study showed
the growth rates of Oreochromis sp. were not affected by different concentrations
of zeolite in feed. |
