Abstract
A study was conducted to evaluate the effect offeed
cycling regimes on growth, survival, feed
conversion ratio, economic conversion index and
body composition of Catla catla. Fingerlings of C.
catla were randomly distributed into control (daily
fed), 2D2F, 4D4F, 6D6F and 8D8F (2, 4, 6, 8 days
deprivation and 2, 4, 6, 8 days feeding,
respectively) feed cycling regimes. Weight gain and
specific growth rate in 4D4F, 6D6F and 8D8F were
significantly (P <0.05) lower than control and 2D2F
feed cycling regime. Feed Conversion Ratio and
Economic Conversion Index were found
significantly (P <0.05) better in 8D8F feed cycling
regime. Feed cycling regimes had significant (P
<0.05) effect on body composition and RNA/DNA
ratio. Protein, lipid and RNA/DNA ratio in 6D6F
and 8D8F were significantly lower than control and
2D2F feed cycling regime.
