Description
Summary:Lipids are essential nutrients for animal. Oxidized lipid might induce injury stress for prawns. This study was conducted to evaluate the oxidized fish oil on growth, digestive enzymes activities, antioxidant system of giant freshwater prawn (Macrobrachium rosenbergii) post-larvae for 21 days with the initial body weight of 1.13 ± 0.04 mg. Three trial diets were with fed the basal diet (C), basal diet supplemented 4% fish oil (4F), basal diet supplemented 4% oxidized fish oil (4OF), respectively (feeding 0 d, 7 d and 14 d, denoted as T7, T14 and T21, respectively). The results showed that the final body weight (FBW) and weight gain ratio (WGR) was increased in the group of 4F and decreased in the group of 4OF. After feeding fish oil or oxidized fish oil, the proteinase activity of T14, T21 post-larvae in 4OF group was significantly higher than T7 post-larvae (P
