多年生花生和郁南假花生的营养成分研究

ANALYSIS OF NUTRITIONAL COMPONENTS OF ARACHIS PINTPI G. AND DESMODIUM HETEROCARPUM S.

对多年生花生和郁南假花生两种牧草的营养成分进行较全面的分析－ 多年生花生和郁南假花生的粗蛋白的含量分别为６－１０％ 和３－７９％ （ 鲜重） 、３１－３７％ 和１５－４８％ （ 干重） ；其纤维素的含量为３－９６％ 和７－９３ ％ （ 鲜重） 、２０－３８ ％ 和２７－２４％ （ 干重）；根据氨基酸分析结果，两种牧草的氨基酸种类齐全，特别是必需氨基酸含量丰富；而且其维生素Ｃ 的含量也比较丰富，分别为４４－５０ 和９－９５ ｍｇ／１００ ｇ；两种牧草的茎叶比分别为１－１７ 和１－３４（ 鲜重）－ 从营养成分角度分析，两种牧草已具备了优良牧草的基本条件－

Arachis pintpi G. and Desmodium heterocarpum S. may become two kinds of popular herbage in Guangdong province. The nutrients of the two herbage are reported in the paper. The coarse protein contents of the two herbage are 6.1% and 3.79% (fresh weight), 31.37% and 15.48% (dry weight), while the fiber contents are 20.38% and 27.24% (dry weight), respectively. Both herbage contain abundant kinds of amino acids, and have a high contents of vitamin C and β-carotene(44.50 mg/100 g and 9.95 mg/100 g, respectively). The ratio of the stem weight to leaf weight is 1.17 and 1.34 (fresh weight) for the two herbage, respectively. It is concluded that they are herbage of fine quality.
