摘要/Abstract

摘要： 试验旨在综合评价从山东省17个市采集的羊常用粗饲料原料的营养价值。试验测定了109个样本10种常用原料的常规营养成分及总能(GE),应用两级离体消化法测定干物质消化率(IVDMD),以计算消化能(DE)和代谢能(ME),并根据预测干物质随意采食量(DMI),进而计算出分级指数(GI)。结果表明,不同粗饲料间的常规养分的差异不能准确地评价饲料营养价值;以NDF、ADF所得GI综合评价粗饲料中营养价值得到苜蓿>冬牧70>地瓜秧>羊草>花生秧>青贮玉米秸>玉米秸>水稻秸>豆秸>麦秸;IVDMD与NDF、ADF均呈显著负相关,而与CP呈显著正相关;DE与NDF、ADF相关性较强,且均呈负相关。

Abstract: This experiment was conducted to evaluate the nutritional value of common forages fed to goats sampled from 17 cities in Shandong Province. A total of 109 samples from 10 species were used to analyze common forage value and gross energy (GE). Forage attributes measured included in vitro dry matter digestibility (IVDMD), digestible energy (DE), metabolizable energy (ME) and crude protein (CP). An acceptability index of all forages was calculated using voluntary dry matter intake. The results revealed that the nutritional value of goat forage cannot be accurately evaluated by conventional nutrient analysis. Digestible energy was highest in alfalfa hay followed by Secale cereale hay, sweet potato vine, Chinese wild rye, peanut stem, corn stalk silage, dried corn stalk, rice straw, soybean straw and wheat straw. IVDMD and DE were significantly negatively correlated with NDF and ADF, while IVDMD was positively correlated with CP.
