中文摘要:
      糖类氧化分解是鱼类能量的重要来源。而且由于糖类来源广泛、价格相对低廉,饲料中添加适量糖类,不仅可以降低饲料成本,而且可以节约蛋白原料添加,减少氨氮排泄。但以往研究表明鱼类对糖的利用能力存在障碍,当摄入超量时则会导致抗病力受损、生长迟缓、脂肪肝、死亡率升高等现象。鱼类肠道微生物参与其糖脂及蛋白等代谢过程,对动物营养代谢有重要调控作用。提高鱼类对饲料的利用率,对鱼类增产、渔民增收具有重要的现实意义。本综述从鱼类糖代谢出发,以鱼类消化道微生物为靶点,阐述肠道微生物调控鱼类糖代谢的方式与可能机制,旨在为鱼类有效利用糖类、节约蛋白质提供新视角。
英文摘要:
      Oxidative decomposition of glucose is an important source of energy for fish. Since carbohydrates are relatively cheap resources, adding appropriate amounts of carbohydrates to the feed can save protein, reduce feed costs, and reduce ammonia nitrogen excretion. However, a large number of studies have shown that fish have low ability to utilize carbohydrates. When carbohydrates content in the feed exceeds a certain level, the fish will suffer from impaired disease resistance, growth retardation, fatty liver, and higher mortality. Intestinal microflora participates in the metabolism of various nutrients such as carbohydrates, lipids and amino acids, which significantly affects the animal nutritional metabolic processes. Increasing the utilization rate of feed has important practical significance for increasing fish production and farmers’ income. This review starts from the carbohydrate metabolism of fish and targets the microbial flora of fish digestive tract. Further, it explains the ways and possible mechanisms associated with the regulation of fish carbohydrate metabolism by intestinal microflora. The content in this review may provide new perspectives for efficient carbohydrates usage and protein saving in fish culture.
