| contents | Effects of Varying Dietary Concentrations of Menadione Nicotinamide Bisulphite (VK) on Growth Performance, Muscle Composition, Liver and Muscle Menaquinone-4 Concentration, and Antioxidant Capacities of Coho Salmon () Alevins. Zhang, Han Yu, Leyong Rahman, Abdur Govindharajan, Sattanathan Li, Lingyao Yu, Hairui Waqas, Muhammad Vitamin K (VK) is an essential micronutrient for fish growth and metabolism. To determine the optimal required dietary concentration of VK, a 12-week-long trial was planned to investigate the impact of VK on growth performance, muscle composition, liver menaquinone-4 (MK-4), whole-body MK-4 concentration, and antioxidant capacity (T-AOC) in coho salmon alevins. A total of 2100 coho salmon alevins were divided into twenty-one tanks, with 100 alevins in each tank, and three tanks represented one group. Each of the seven groups were randomly assigned to one of the experimental diets formulated with varying levels of menadione nicotinamide bisulphite (VK), i.e., 0.16 (control), 5.25, 10.22, 14.93, 20.51, 40.09, and 59.87 mg/kg, respectively. The results revealed that the inclusion of VK from 5.25 to 40.09 mg/kg improved ( < 0.05) the survival rate (SR), weight gain (WG), specific growth rate (SGR), and feed conversion ratio (FCR), while no effect ( > 0.05) was observed on the hepatosomatic index (HSI), viscerosomatic index (VSI), Fulton's condition factor (K), and muscle composition. The whole-body MK-4, liver MK-4, liver T-AOC, total superoxide dismutase (T-SOD), and catalase (CAT) enzymes were also increased ( < 0.05). Malondialdehyde (MDA) contents were reduced ( < 0.05) in all supplemented groups with a decreasing trend. The predicted optimal required dietary concentrations of VK were found to be 34.0, 43.5, 38.54, and 31.97 mg/kg based on WG, SGR, liver MK-4 concentration, and T-AOC, respectively, by quadratic regression analysis. It is concluded that the dietary VK has improved the growth performance and antioxidant status in alevins during early development in the range of 31.97 to 43.5 mg/kg diet. |
