配合饲料替代活饵对翘嘴鳜生长性能、消化功能及抗氧化能力的影响
Effect of Replacing Live Bait with Compound Feed on Growth Performance,Digestive Function and Antioxidant Capacity of Siniperca chuatsi
摘要
Abstract
Siniperca chuatsi is an important high-quality freshwater aquaculture species in China.As a naturally carnivorous and highly predatory fish,it primarily feeds on live bait.Artificial domestication methods to alter the dietary habits of carnivorous fish can reduce farming costs and decrease reliance on natural resources.To investigate the effects of replacing live bait with compound feed on the growth performance,digestive function and antioxidant capacity of S.chuatsi,juvenile S.chuatsi(23.17±0.75 g)were divided into 3 groups:compound feed(F group),live bait(B group),a mixed diet of one meal of compound feed and one meal of live bait(M group).After 3 months of farming,growth performance indicators were measured,digestive and antioxidant enzyme activities were assessed,and the microstructures of the gastrointestinal tract were observed.The results showed that the body weight and body length of F group were significantly higher than those of M group,and the feed conversion ratio of F group was significantly lower than that of B group.However,no significant differences were observed in total length,body height,condition factor,hepatosomatic index,and viscerosomatic index among the 3 groups.The superoxide dismutase activity in F and M groups was significantly higher than that in B group,while the catalase activity in B and M groups was significantly higher than that in F group.The reduced glutathione content and glutathione peroxidase activity in F group were significantly higher than those in M group,and the total antioxidant capacity in B group was significantly higher than that in M group.No significant differences were observed in malondialdehyde content among the 3 groups.In gastric tissues,the trypsin activity in M group was significantly lower than that in B group,while the amylase activity in F group was significantly higher than that in B group.No significant differences were observed in gastric lipase activity and intestinal digestive enzyme activities among the 3 groups.The intestinal villus height in the F group was significantly greater than that in B and M groups.Compared to B group,the intestinal villi in F and M groups were sparser,with increased inter-villus spaces in the intestinal lumen.In conclusion,domesticated S.chuatsi fed with compound feed showed no adverse effects on growth performance,although M group was less effective than the other 2 groups.The fish adapted to the compound feed by enhancing amylase activity,increasing specific antioxidant enzyme activities,and improving intestinal villus height and inter-villus spaces.Above results provided theoretical basis for the large-scale farming of S.chuatsi using formulated feed and further optimization of feed composition.关键词
