Abstract

To evaluate the nutritive values of outdoor mass cultivated Spirulina platensis both chemical analysis and bioassay were carried out using adult cockerels. Blue-green algae, Spirulina platensis contained about 71g /l00g DM of crude protein with balanced amino acid profiles although methionine is liable to he limiting to animals. Compared to fish meal, calcium content and calcium : phosphorus ratio of the Spirulina were not suitable in terms of animal requirements. Reasonable amount of y-linolenic acid(C18: 3 $\omega$6) in Spirulina platensis draws a clinical attention due to its historically recognized pharmacotheraputic functions. Metabolizable energy contents of Spirulina were 3.67 and 3.11 mcal /kg DM for TMEn and AMFn, respectively, which therefore, can he a reliable energy source for poultry. True amino acid availabilities of essential amino acids of Spirulina platensis were higher than 90% for poultry, which is better than comparative ingredient like fish meal. Overall data from both chemical analysis and bioassay demonstrated that the Spirulina platensis could he a favorable protein feedstuffs for poultry.
