间歇禁食对大黄鱼生长、生理生化和肠道组织结构的影响
Effects of intermittent fasting on growth,physiology and biochemistry,and intestinal histology of the large yellow croaker(Larimichthys crocea)
摘要
Abstract
Whether in the wild or in captivity,large yellow croaker(Larimichthys crocea)may suffer from starvation.To study the effects of starvation and restoration feeding on large yellow croaker,The experiment was conducted with a sample of large yellow croaker with an initial body weight of(122.62±11.08)g and a body length of(17.90±1.04)cm.The fish were starved for 0,2,4,8 or 16 d(S0,S2,S4,S8,S16)and then feeding was resumed.The results are as follows:the body weights of the starved groups showed a decreasing trend,and the largest decrease was observed in group S8.After resumption of feeding,all the starved groups showed only partial compensatory growth capacity at the end of the experiment,among which the S8 and S16 groups showed lower compensatory growth capacity.Serum glucose,triglyceride,alkaline phosphatase(AKP)and acid phosphatase(ACP)tended to decrease with the extension of starvation time,and reached the lowest at 8 days of starvation.At the end of the experiment,its indicators did not recover significantly after 8d of refeeding.In addition,cortisol concentration and superoxide dismutase(SOD)activity rose to the highest at 8 days of starvation,while the recovery was not obvious after refeeding.The intestinal tissue structure of large yellow croaker was basically consistent with its physiological and biochemical trends,and the height of intestinal villi and the thickness of muscularis propria decreased to the lowest level at 8 days of starvation,and the recovery was not obvious after refeeding.IL-1β,IL-10 and TNF-α gene expression in the intestine increased with starvation,was highest in the S4 group and decreased after resumption of feeding.The results showed that:In summary,under the conditions of this experiment,starvation stress lasting for 8 days would have a significant effect on large yellow croaker.Therefore,in order to ensure the feeding effect,it is recommended that the length of starvation of the large yellow croaker should be controlled within 8 days.关键词
