新引1号东方山羊豆牧草品质的评价

Evaluation of forage quality of Galega orientalis cv. Xinyin No.1

对新引1号东方山羊豆(Galega orientaliscv.Xinyin No.1)与被誉为"牧草之王"的新疆大叶苜蓿(Medica-go sativa cv.Xinjiang Daye)中营养物质含量进行测定和分析比较。结果表明,新引1号东方山羊豆营养价值较高,初花期粗蛋白含量23.88%,粗纤维含量25.48%,中性洗涤纤维和酸性洗涤纤维含量适中,分别为43.17%和45.35%;氨基酸种类齐全,组成平衡,氨基酸总量14.17%,满足总必需氨基酸/总氨基酸=0.78>0.60,总必需氨基酸/总非必需氨基酸=0.43>0.40,为优质的家畜蛋白源;单宁含量为0.93%,反刍家畜青饲不会发生臌胀病。该牧草具较高的饲用价值,适宜地区可作为主要推广品种。

The nutrient,type of amino acid and content,neutral detergent fiber,acid detergent fiber,and tannin content of a new introduced species Galega orientalis and Medicago sativa cv.Xinjiang Daye were determined.The results showed that the nutritive value of G.orientalis cv.Xinyin No.1 was high,the content of crude protein and crude fiber in initial flowering stage was 23.88% and 25.48%.The content of neutral detergent fiber and acid detergent fiber were 43.17% and 45.35%,respectively.The kinds of amino acid and composition was complete and balanced,the total amino acid was 14.17%,EAA/NEAA=0.780.60,EAA/TAA=0.430.40,was a high quality protein source of livestock.The content of tannin was 0.93%,even green feed the ruminant tympanites would not happen.It has high feeding value,and can be used as commercial cultivars in its suitable area.
