| Abstract: | 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. |
