摘要
利用测定资料及西德奥斯卡凯尔纳的预测能值公式,对呼图壁县农区奶牛主要饲草能值(EV)、消化能(DE)、代谢能(ME)、产奶净能(NEL)进行了预测分析。结果表明:青贮玉米和苜蓿干草的DE、ME、NEL指标较高,登海-9玉米秸秆的DE、ME、NEL均比SC-704和东单-7高。
Using the determination material and the West German Oscar Koerner's forecast could the value formula, to the Hutubi County agriculture area cow main forage grass be able value (EV), the digestion to be able (DE), metabolism to be able (ME), the milk production only to be able (NEL) to carry on the forecast analysis.The result indicated that,The silage corn and alfalfa hay DE, ME, the NEL target is high, ascends the sea - 9 corn straw stalk DE, ME, NEL compared to SC-704 and Dongdan - 7 high.
