Determination and Nutritional Evaluation of Amino Acids in Staple Food Bamboo for Giant Panda in Qinling Mountains
[Objective] The aim of study was to further know nutrition need of Qinling panda. [Method] The composition and contents of amino acids in three kinds of staple food bamboo (Bashania fargesii, Fargesia qinlingensis and F. dracocephala) for giant panda in Qinling Mountains were determined by the automatic amino acid analyzer and their nutrition were evaluated together. [Result]The results showed that samples were hydrolyzed with acid into 17 kinds of amino acids including 8 kinds of essential amino acids. For all samples,Glu content was highest,followed by Asp、Leu、Phe、Val、Ala、Lys、Gly、 Pro、Thr、Ile、Arg and Ser, Cys content was the lowest.Except the content of Cys in bamboo leaves was lower than that in stem, contents of other amino acids in bamboo leaves were significant higher than those of in bamboo stem.The proportions of amino acids were higher than the WHO/ FAO standard. In this way, these bamboos could provide protein source in good quality for daily life of giant panda in Qinling Mountains. [Conclusion]This study will provide scientific basis for food resources protection and sustainable development of giant panda in Qinling Mountains.
