Abstract:Cynoglossus semilaevis blood biochemical parameters and antioxidant indexes that respond to fishing stress were measured under the influence of different feed taurine levels. With taurine levels of 0%, 0.5%, 1% and 1.5%, 4 groups of test feeds were prepared. After 28 days of feeding. Serum was collected before stress and at 0, 4, 12, 24, 48, 96 h after stress to determine the content of total protein, cholesterol, GPT, GOT, nitric oxide, lysozyme, blood sugar and the activity of glutathione (GSH-PX), superoxide dismutase (SOD), malondialdehyde (MDA) and antioxidant capacity (AOC), the results show: Feeding a feed with a taurine content of 0.5% has a better inhibitory effect on cholesterol and GOT in Cynoglossus semilaevis after fishing stress, and has obvious anti-stress effect on lysozyme and protein. The 0.5% group had the lowest MDA content 12 h after fishing stress. The results suggested that feeding the feed with a taurine content of 0.5%, the Cynoglossus semilaevis blood biochemical parameters and antioxidant indexes to fishing stress has a better response.
