Microalgae, such as (CV), have been identified as promising animal feed sources due to their high content of essential nutrients, including proteins, total lipids, n-3 polyunsaturated fatty acids, and pigments. This study aimed to review the digestibility, bioaccessibility, and bioavailability of nutrients from CV biomass, and to analyse strategies to enhance their digestibility in monogastric animal diets. The study conducted a systematic review of the literature from databases such as PubMed, Scopus, Google Scholar, and Web of Science, up until the end of January 2023. The results of adding CV to poultry and swine diets were diverse and depended on a number of variables. However, pre-treatments applied to CV biomass improved nutrient digestibility and accessibility. CV biomass, produced in a cost-effective manner, has the potential to serve as a supplement or substitute for expensive feed ingredients and improve animal health, physiology, and immune status. Variations in results may be due to differences in microalgal strain, cultivation conditions, and dietary inclusion levels, among other factors. This study provides new insights and perspectives into the utilization of CV biomass in animal diets, highlighting its potential as a valuable ingredient to improve nutrient utilization.
微藻，如 （某种特定微藻，原文未给出具体名称，此处用“（CV）”表示），因其富含蛋白质、总脂质、n - 3多不饱和脂肪酸和色素等必需营养素，已被确定为有前景的动物饲料来源。本研究旨在综述（CV）生物质中营养素的消化率、生物可及性和生物利用率，并分析提高其在单胃动物日粮中消化率的策略。该研究对截至2023年1月底来自PubMed、Scopus、谷歌学术和科学网等数据库的文献进行了系统综述。在禽类和猪的日粮中添加（CV）的结果各不相同，且取决于多个变量。然而，对（CV）生物质进行预处理可提高营养素的消化率和可及性。以具有成本效益的方式生产的（CV）生物质有潜力作为昂贵饲料成分的补充或替代品，并改善动物健康、生理和免疫状态。结果的差异可能归因于微藻菌株、培养条件和日粮添加水平等因素的不同。本研究为（CV）生物质在动物日粮中的利用提供了新的见解和观点，突出了其作为提高营养物质利用率的宝贵成分的潜力。
