摘要
对上海地区4个牧场7批苜蓿干草的主要营养成分分析表明,平均干物质含量、粗蛋白、粗脂肪、粗灰分、中性洗涤纤维和酸性洗涤纤维分别为91.45％、18.60％、2.85％、10.11％、44.35％和31.38％。钙、磷、镁、钾、钠和氯含量分别为1.62％、0.25％、0.31％、1.61％、0.15％和0.61％。微量元素硒、锌、铁、铜和锰含量分别为0.12ppm、25ppm、456ppm、9ppm和39ppm。经计算,总可消化养分和产奶净能(3倍于维持水平)分别为58.34％和1.38Mcal/kg。结果显示,总可消化养分和产奶净能较多,但微量元素硒普遍缺乏。
A general analysis about 7 alfalfa hay samples from 4 dairy farms in Shanghai area were developed. The results showed that the contents of DM, CP, EE, CAsh, NDF and ADF were91.45%, 18.60%, 2.85%, 10.11%, 44.35% and 31.38% respectively. In samples, the contents of Ca, P, Mg, K, Na and Cl were 1.62%, 0.25%, 0.31%, 1.61%, 0.15% and 0.61% respectively and microelements such as Se, Zn, Fe, Cu and Mn were 0.12ppm, 25ppm, 456ppm, 9ppm and 39ppm respectively. The TDN and NEL3x, calculated from experimental data, were 58.34% and 1.38 Meal/kg respectively. Although TDN and NEL3x were abundant in alfalfa hay inShanghai area it indicated that Selenium was absent.
