中文摘要:
      以主成份分析和聚类分析的方法,对中国25个不同地理品系卤虫卵的营养成分(脂类、氨基酸、蛋白质、维生素)进行了分析和研究。实验结果显示:(1)通过对不同地理品系卤虫卵的43个营养因子的主成分分析和聚类分析可把25个不同地理品系卤虫卵分为二个大的类群:海水型和淡水型卤虫卵。(2)C20:5n-3、C18:3n-3、蛋白质含量、C16:1、四种营养成分的含量是区别不同地理品系卤虫卵的主要营养特征。(3)生殖方式不影响各品系的营养成分的组成,而地理品系间营养成分存在差别。(4)淡水型卤早虫卵适合于投喂淡水养殖动物,而海水型卤虫卵适合于海水型养殖动物。
英文摘要:
      The nutritional compositions of 25 Artemia cysts of different geographic strains from China were analysed by means of principal component s analysis and cluster analysis. The total amount of lipids, amino acids, protein and vitamins were analysed. The experimental results showed: ( 1) Artemia cysts of 25 strains can be divided 2 groups: A. freshwater-type cysts and B. marine-type cysts by the methods of principal component analysis and cluster analysis of 43 nutrit ional factors. ( 2) C20: 5n- 3, C18: 3n- 3, proteins, C16: 1 were primary nutrit ional components among Artemia cysts of different geographic strains. ( 3) Reproductive type can not af fect the nutritional composit ion, but there were difference among Artemia cysts of different geographic strains. ( 4) The freshwater type Artemia cysts only suitable for feeding to freshwater-animals and marine-type Artemia cysts containing C20: 5n- 3 suitable for feeding to marine animals.
