Marine macroalgae are considered as promising sustainable alternatives to conventional terrestrial animal feed resources. The advantages include high growth rate, potential cultivation in saltwater, and no occupation of arable land. Macroalgae are broadly classified as brown (Phaeophyta), red (Rhodophyta) and green (Chlorophyta) algae, and are a diverse group of marine organisms. The nutritional value of macroalgae is highly variable. The protein and essential amino acid content can be low, especially in brown species, and indigestible polysaccharides adversely affect the energy value. Optimal use of macroalgae in feeds requires suitable processing, and biorefinery approaches may increase protein content and improve nutrient availability. Macroalgae are rich in unique bioactive components and there is a growing interest in the potentially beneficial health effects of compounds such as laminarin and fucoidan in different macroalgal and macroalgal products. This review summarizes current literature on different aspects of the use of macroalgae as sources of protein and health-promoting bioactive compounds in feed for monogastric animal species. © 2018 The Authors.

海洋大型藻类被认为是有前途的可持续替代传统陆地动物饲料资源。其优点包括生长速度快、有在海水中培养的潜力、不占用耕地。大型藻类广泛分为褐藻（Phaeophyta）、红藻（Rhodophyta）和绿藻（Chlorophyta），是海洋生物多样性的一个群体。大型藻类的营养价值变化很大。蛋白质和必需氨基酸的含量可能较低，尤其是在褐藻中，而且不可消化的多糖会对能量值产生不利影响。要使大型藻类在饲料中得到最佳利用，需要进行适当的加工，而生物精炼方法可能会提高蛋白质含量并改善营养物质的可用性。大型藻类富含独特的生物活性成分，人们对不同大型藻类和藻类产品中化合物如岩藻聚糖和褐藻糖胶的潜在有益健康影响越来越感兴趣。本文综述了目前关于大型藻类作为单胃动物饲料中蛋白质和促进健康的生物活性化合物来源的不同方面的文献。 © 2018 作者。John Wiley & Sons Ltd 代表化学工业协会出版的《食品科学杂志》。
