EFFECT OF USING SUNFLOWER AND CANOLA OILS IN COMMON CARP (CYPRINUS CARPIO L.) DIETS ON GROWTH PARAMETERS, FEED UTILIZATION AND BODY COMPOSITION

Abstract

The fish production industry has become one of the most important animal production projects, and fish industry suffer from feed costs, so this study aims to find accessible food additives that increase production or reduce costs. This was done by 126 fish of common carp (Cyprinus carpio L.) Average individual weight 42.72 g ± 2.28 g. and 254.78 g ± 2.95 g biomass weight. were randomly distributed to 21 aquaria, with seven treatments with three replicates, 6 fish per aquarium. Fish were fed 3% by weight of biomass, on a prepared diet with a protein content of 28%. It was divided into seven sections by treatments, T1 without addition, T2, T3and T4 adding sunflower oil 2, 4 and 6 g/kg, consecutively, T5, T6 and T7 adding canola oil 2, 4, and6 g/kg consecutively. The experiment period lasted 70 days, and weight data were taken every two weeks. Studied growth indicators (WG) Weight gain (DWG) Daily weight gain (RGR) Relative growth rate (SGR) Specific growth rate, feed utilization indicators Feed conversion rate (FCR), feed efficiency rate (FER), protein efficiency rate (PER). The fish body components were studied. The results showed a significant superiority (p≤ 0.05) of T5, T6 and T7 treatments over all treatments of growth indicators. Similarly for indices of food use, treatments T5, T6 and T7 significantly outperformed (p≤ 0.05) in all experimental treatments for FER and PER indices.
