Studies on the Growth Performance and Feed Conversion Ratio of Catlacatla Fed with Different Levels of Animal and Plant based Dietary Lipids

Abstract

Current research was designed to estimate effect of plant and animal based dietary lipids on growth and body composition of Catlacatla. Fish feed ingredients were grouped with two categories i.e. animal based lipids and plant based lipids. Each treatment including control had two replicates. Maximum weight gain was observed in treatment T6 treated with 9% animal based unsaturated fats and the value is (48.58±17.44) and significantly lowest growth (<0.05) was measured in T0 group. In present study, maximum body weight was observed in T9 (49.3±19.48) and least was calculated in T21 (37.15±11.64). Maximum total length was measured in T2 (9.76±3.34) fed with 6% animal based saturated dietary lipids. Feed utilization was calculated by FCR. Top FCR (< 0.05) value was observed for T9 (0.40±0.06) that was given 9% plant based MUFA. Least FCR was calculated in T21 that is (1.05±0.69). Body composition of fish such as protein, ash and moisture contents was unchanged by different levels of lipid but lipid content was increased. It was concluded that synthetic feed supplemented with 6% and 9% dietary lipids either derived from animal or plant sources are acceptable for improved growth of catlacatla and with no negative impacts on growth performance.
