摘　　要：与传统作物相比,微藻具有营养丰富、种植占地面积小、不受季节影响、环境适应性强、光合作用速率强、繁殖快等优点。微藻富含碳水化合物、必需脂肪酸、氨基酸和维生素等多种营养物质,可满足家畜营养需要,且微藻中的不饱和脂肪酸可通过影响反刍动物瘤胃微生物菌群结构以及脂肪酸的氢化作用抑制甲烷产生。微藻具有安全、无毒,且极高的利用价值,是理想的绿色饲料添加剂。文章介绍了微藻的营养成分以及微藻对反刍动物生长性能、肉品质、泌乳性能、免疫机能、抗氧化能力、瘤胃发酵等方面的影响,展望了微藻在反刍动物饲料中的应用前景,以期为微藻的开发与应用提供参考。Compared with traditional crops,microalgae has the advantages of rich nutrition,small planting area,not affected by seasons,strong environmental adaptability,high photosynthesis rate and fast reproduction.Microalgae are rich in many nutrients such as carbohydrates,essential fatty acids,amino acids and vitamins,which can meet the nutritional needs of livestock.Moreover,unsaturated fatty acids in microalgae can inhibit methane production by affecting the structure of rumen microflora and the hydrogenation of fatty acids.Microalgae is safe,non-toxic and has high utilization value,which is an ideal green feed additive.The paper introduces the nutritional composition of microalgae and the effect of microalgae on growth performance,meat quality,lactation performance,immune function,antioxidant capacity and rumen fermentation of ruminants,prospects the application prospect of microalgae in ruminant feed,in order to provide reference for the development and application of microalgae.
