Increasing demand for protein, especially animal-based proteins and the large amounts of protein feed inputs required for production, has largely driven the research on spirulina as an animal feed. This short communication summarizes the results from two larger research projects investigating spirulina as an animal feed. Overall, spirulina appears to be a prospective protein source in poultry and pork production, as well as aquaculture. However, spirulina as a feed can have implications for system productivity and end product quality, depending on animal production system. Neither swine productivity nor product quality was negatively affected with spirulina as a feed, which is likely due to the low amounts of protein required in swine finishing diets. Spirulina as a feed does negatively affect poultry and fish productivity as well as alter product quality, primarily raw meat color. Therefore, future research focused on sustainability analysis and product processing and acceptance should investigate the trade-offs of incorporating spirulina into poultry and fish diets.
对蛋白质，尤其是动物源蛋白质的需求不断增加，以及生产所需的大量蛋白质饲料投入，在很大程度上推动了将螺旋藻作为动物饲料的研究。本简短通讯总结了两项关于螺旋藻作为动物饲料的大型研究项目的结果。总体而言，螺旋藻似乎是家禽、猪肉生产以及水产养殖中一种有前景的蛋白质来源。然而，根据动物生产系统的不同，螺旋藻作为饲料可能会对系统生产力和最终产品质量产生影响。以螺旋藻作为饲料，猪的生产力和产品质量均未受到负面影响，这可能是由于猪育肥日粮所需蛋白质含量较低。螺旋藻作为饲料确实会对家禽和鱼类的生产力产生负面影响，并改变产品质量，主要是生肉颜色。因此，未来专注于可持续性分析以及产品加工与接受度的研究应调查将螺旋藻纳入家禽和鱼类日粮的权衡取舍。
