Abstract: The contents of crude protein and 18 kinds of amino acids in the powder of tetraploidy black locust for fodder leaves at four stages, from which Langfang, Hebei Province, were determined. Their value for feeding were evaluated by means of amino acid scores (AAS) and essential amino acid index (EAAI). The results showed that the crude protein content, the eighteen essential amino acids and the twelve essential amino acids in the powder of tetraploidy black locust for fodder leaves were highly at the four stages, and along with the time process, they were all descending gradually. Moreover, their essential amino acid score (AAS) were also highly and their amino acid were balanceable. And their essential amino acid index (EAAI) of cattle, pig, chicken, duck, goose, fish, prawn and sheep were higher than 0.86, therefore they can be the excellent fodder of these animals. Furthermore, its biomass and nutrition both reached the highpoint in the middle or latter ten days of a month when were appropriate for picking or cradling.

Key words: Tetraploidy black locust, Powder of leaves, Protein, Amino acid, Nutritional evaluation
