Basic Biochemical Constituents and Profiles of Amino Acids in the Post Larvae of Macrobrachium rosenbergii Fed with Spirulina and Yeast Enriched Artemia

摘要

This study was aimed to assess the growth performance of Macrobrachium rosenbergii post larvae fed with Spirulina and yeast enriched Artemia for 60 days. The length and body weight in prawns fed with enriched Artemia were increased significantly (P<0.05) However, Spirulina enriched Artemia fed prawns produced better growth than that of the yeast enriched Artemia fed prawns. Spirulina enriched Artemia acquired more level of total protein, amino acids and lipid than yeast enriched Artemia . While, yeast enriched Artemia acquired higher level of total carbohydrate than that of the Spirulina enriched Artemia . The similar trends in the content of biochemical constituents were also recorded in prawns fed with enriched Artemia . The content of essential amino acids, such as phenylalanine, leucine, tyrosine, isoleucine, tryptophan, methionine, valine, threonine, arginine, histidine and lysine were found to be higher in prawns fed with Spirulina enriched Artemia than that of prawns fed with yeast enriched Artemia . Spirulina has produced better growth in M. rosenbergii than that of yeast . However, yeast as well produced appreciable growth when compared with control. Therefore, both Spirulina and yeast can be taken as supplementary materials in feed management practices.
