摘要 研究通过对江西反刍动物常用粗饲料体外消化率(IVDMD)的实际测定,证明邓卫东等(2002)建立的以范氏纤维含量为预测因子的粗饲料IVDMD预测模型在江西区域有较高的准确性,能够应用于江西反刍动物粗饲料消化率的预测。该模型与张吉鹍等(2004b;2010)建立的粗饲料干物质采食量预测模型构成了完整的反刍动物粗饲料分级指数(GI)参数模型,这将大力推进江西反刍动物粗饲料品质的综合评定。 In vitro dry matter digestibility (IVDMD) for 10 forages was measured to prove the IVDMD calculating models built by Deng (2002) with neutral detergent fiber (NDF) or acid detergent fiber (ADF) and acid detergent lignin (ADL) as predictors individually. It was proved that the models could be used to calculated the IVDMD of forages produced in Jiangxi province. These calculating models for IVDMD and the calculating models for dry matter intake built by Zhang models of grading index (GI) for ruminant forages and this (2004b;2010) constituted the whole parameter will propelled the comprehensive evaluation of ruminant forage quality in Jiangxi.
