太子参茎叶作饲料原料的营养价值分析

Nutrition Analysis on Stems and Leaves of Radix pseudostellariae as Forage

摘要: 为开发太子参茎叶作为饲料新原料,研究太子参茎叶营养成分,系统分析太子参茎叶的常规营养成分和氨基酸组分,并对其营养价值进行分析。结果表明,太子参茎叶营养成分含量:粗蛋白13.39%、粗脂肪2.57%、粗纤维8.32%、钙0.95%、磷0.53%;太子参茎叶总氨基酸为10.83%,必需氨基酸和非必需氨基酸分别是4.40%和6.43%,E/T值40.6%,E/N值68.4%;太子参茎叶第一限制氨基酸为蛋氨酸+胱氨酸,氨基酸过剩最多的是苯丙氨酸+酪氨酸。太子参茎叶蛋白接近于FAO/WHO提出的理想蛋白质条件;且其氨基酸组成成分齐全、含量丰富,具有一定的饲用价值。

Abstract: Nutritional composition of the stems and leaves of ginseng,Radix pseudostellariae,was analyzed to determine their potential use for feed.The results showed that the ginseng stems and leaves contained 13.39%crude protein,2.57%fat,8.32%crude fiber,0.95%calcium,and 0.53% phosphorous.The proteins had 10.83%total amino acids,4.40% essential amino acid and 6.43% nonessential amino acid,an E/N ratio of 68.4% and an E/T ratio up to 40.6%,with Met+Cys the greatest limiting essential amino acid but abundant on Phe and Tyr.Quality of the protein was close to the FAO/WHO recommended level.Therefore,the stems and leaves of the ginseng could possibly become a new source of feeding material for domesticated livestock.
