| Popis: | An 8-week growth trial was conducted to evaluate the effects of alpha-ketoglutarate (AKG) on growth performance and serum biochemical parameters of grass carp (Ctenopharyngodon idella), and to determine the optimal amount of AKG in feeds. A total of 450 grass carp (mean initial body weight, 35.64±1.39 g) were randomly divided into five treatment groups, with three replicates each. Treatments were, basal diet supplemented with 0% (the control group), 0.25%, 0.5%, 0.75% and 1% AKG, respectively. The results showed that fish fed the 0.75% AKG diet had significantly higher final body weight, weight gain rate (WGR), specific growth rate (SGR), serum superoxide dismutase (SOD) activity, lysozyme (LSZ) activity, and significantly lower feed conversion ratio (FCR), viscerasomatic index (VSI), serum malondialdehyde (MDA), and UREA content than fish fed the control diet (p0.05). The present study suggests that feed supplementation with 0.75% AKG can promote growth of Ctenopharyngodon idella fingerlings, enhance antioxidant capacity and their non-specific immunity. |
