水煮和提取处理对中草药干物质消化率和小肠可消化蛋白质的影响
Effect of boiling and extraction on dry matter digestibility and intestine-digestible crude protein levels in plant residue following Chinese medicinal herb preparation
摘要
Abstract
The aim of this study was to assess the effects of boiling and extraction on dry matter digestibility and intestine-digestible protein content of plant residue from production of Chinese herbal medicines.This information is relevant to assessing the usefulness of these residues for animal feeding.Using a mobile nylon bag technique, various digestive degradation kinetic parameters were determined for processing residues of Astragalus (Astragalus membranaceus), malt (Hordeum vulgare) and Licorice (Glycyrrhiza uralensis).Parameter estimates obtained for the three plant materials included:the effective degradability (ED) in the rumen of the main dry matter (DM) nutritive components (crude protein, neutral and acid detergent fiber;CP, NDF, ADF, respectively), the small intestine digestibility (Idg), and their rumen non-degradable dry matter (UDDM) and non-degradable protein (UDP) for both raw plant materials and after boiling and extraction.It was found that:1) The EDDMand EDCPof the three tested residues after boiling and extraction were significantly lower than those of the untreated raw materials (P＜0.05), while EDNDFand EDADF were significantly higher than the untreated materials (P＜0.05);2) The IdgUDDMand IdgUDPafter boiling and extraction, of the three tested Chinese herbal medicine preparation residues, were significantly higher than those of the untreated raw materials (P＜0.05);3) Boiling significantly increased the DDM of all 3tested residues (P＜0.05), and also the IdgCP, and IdgCP/CP of malt extract residue (P＜0.05), but significantly reduced IdgCP, and IdgCP/CP of licorice extract residues and the IdgCPof Astragalus extract residues (P＜0.05).These results indicate that it is not necessary to boil these feeds unless there is a special requirement to do so.Malt extract residues have good nutritional potential as a high-quality refined feed;Astragalus and licorice extraction residues have nutritional potential as a quality roughage.关键词
