饲料在动物生长和健康中扮演着重要的角色,然而决定饲料表现的内在机一直是一个所谓的“黑箱”。直到近年来,研究证明营养素能够作为信号分子被细胞和机体感知,并在调控基因表达和代谢活动中起着至关重要的作用。多条分别感知不同营养素的信号通路被发现,营养感知信号调节也已在临床医学中被广泛用于药物开发与疾病控制。然而,在陆生和水产养殖动物中,对主要营养素(蛋白质、糖脂等)的营养感知和代谢调控的研究仍处于起步阶段。因此,我们针对未来在动物营养学中开展营养感知研究可能的研究主题和应用场景提出设想和建议。

本文综述了我国水产养殖动物营养学研究和饲料工程方面近期的研究,分析了产业发展的问题,探讨了下一步的政策措施。可以发现,过去10多年里,水产动物营养与饲料的发展在营养素需求、动物的摄食与投喂、仔稚鱼饲料、亲本营养、添加剂等方面取得了重要的进展,但仍然存在饵料系数高、环境排放大、饲料成本高、效益不稳定等问题。下一步的研究应该以“安全高效,节约环保”为目标,引入生态学和现代组学理念,开展水产动物营养代谢的分子机理、动物的营养需要与精准饲料配方技术、饲料质量控制与加工工艺、精准投喂技术、品质调控技术等方面的研究,同时在政策上应该扩大学科交流、实行长期稳定支持等。

Ecological security evaluation of Africa

Africa, the second largest continent in the world, has achieved remarkable economic and political results through exploration and positive development. Ecological security comprehensively reflects the heath and integrity of an ecosystem, and it is broadly defined as the security state of a complex artificial ecosystem composed of natural, economic and social factors. Ecological security determines the potential for sustainable development in Africa, especially with its rapidly developing economies. However, there is a lack of information on the ecological security state of the continent as a whole. In this study, we constructed an evaluation system based on a pressure-state-response model and evaluated the ecological security state of all 54 African countries. The results showed that, at the national level, the ecological security state of the countries in Africa differed, as did their spatial and temporal variations from 1995 to 2016. In general, African countries showed relatively good ecological security. The years 2007 and 2001 were the worst and best years, respectively, in terms of ecological security during the study period. At the regional level, North Africa and West Africa had the best and worst ecological security, respectively.

Interest in understanding the digestion behavior of starch in the presence of dietary fibers is growing due to the ability of dietary component to control the release and absorption of glucose. This presents an outstanding opportunity to improve the quality of food products by incorporating dietary fiber into starchy food products. The physicochemical properties of different fibers and their behavior in the gastrointestinal tract (GIT) differ. To test the efficacy of these different fibers on starch digestion, static in vitro digestion models under conditions that mimic the human GIT are frequently used. Indeed, many efforts have been committed to the development of various static in vitro protocols for starch digestion. Though not considered as the gold standard in digestibility studies in food science and technology, static simulated models provide a useful alternative to in vivo techniques for rapid screening of the digestibility of food products under conditions that simulate the human GIT. This review presents the current status and development of digestion techniques for simulating digestion conditions in the human GIT, with particular interest on starch digestion in the presence of dietary fiber in the three phases of digestions including the oral, gastric and the intestinal steps. This summary can benefit investigators in developing static in vitro digestion models designed to simulate starch digestion with relevant values of the quantifiable parameters, including pH, enzymes and simulated digestive fluids.
