摘要
本研究利用植物茎叶提取浓缩叶蛋白的结果表明，植物茎叶提取的浓缩蛋白中的粗蛋白含量达３２．４１～５２．９９％，为原茎叶粗蛋白含量的２２．４～７４．２％。据测定，氨基酸总量最高达５８．４６％，赖氨酸达６．２２％，超过ＦＡＯ的推荐量（４．２％）。矿物质营养丰富，尤其是Ｆｅ、Ｍｎ、Ｚｎ含量较高。饲喂ＴＤ鸭用２～８％叶蛋白代替鱼粉或豆饼，饲养效果好。用４％叶蛋白饲喂ＡＡ肉鸡（雏鸡）成活率为１００％，总体重为６９２±１８克，饲料报酬为２．０３∶１，均超过鱼粉的对照组。
The nutritive composition and feeding effects of protein concentrate extracted from stems and leaves of plants were studied in this experiment. The results showed that the crude protein content (CPC) in the concoutrate got to 32.41～52.99%, or over 22.4～74.2% of normal CPC in original stems and leaves. There were rich and an kinds of amino acids in the concentrate with the hishest total content of amim being 58.46% and lysine content 6.22% that was greaty higher than 4.2% recom mended by FAO. The concentrate also contained abundant mineral nutrients and Fe, Mn and Zn in paarticular. 2～8% of the protein concentrale was analogous to fish meal and bean cake in effects of feeding TD ducks. For feeding of AA chickens, 4% of the protei cincentrate was superior to the check of fish meal with the suruival rate being 100%, total weisht 692±18g and feed conversiov rate 2.03∶1.
