摘要
本文对蛋鸡饲料与鸡粪进行了13次16种氨基酸含量的测定分析,氨基酸含量稳定,鸡粪中氨基酸含量比常用的部分饲料中氨基酸含量高。鸡对饲料中蛋白质的利用率仅为29%;大部分蛋白质仍在鸡粪中,从分析结果看,100克鸡粪中含有各种氨基酸10.45克。鸡粪取材广泛,价格低廉,氨基酸便于提取,有广阔的开发利用前景。
The content of nitrogen and amino acids in 7 species of marine algae are determined.The result shows that the nitrogen content is 4. 04%~9. 86%. The nitrogen and amino acid contents are arranged in the following order: Spirulina lateusis>Dunaliella Salina>Tetraesmrs Subcordiformis>Platymouas Subcordiformis>Sneletoneme Costatam>Phaeodactvium tricornutum>Chaetoceros melleri.About 17 kinds of amino acid were determined and their contents are 1. 23%~9. 94%.
