为探索天津地区芦苇的营养成分变化规律,为芦苇饲料化利用奠定基础,试验采集天津主要芦苇产地不同生长时期的芦苇,并对其常规营养成分进行测定.结果表明:从展叶期到枯叶期,天津各地芦苇的粗蛋白质(CP)、粗灰分、钙(Ca)和磷(P)含量呈下降趋势;干物质(DM)和酸性洗涤木质素含量呈上升趋势;中性洗涤纤维(NDF)和酸性洗涤纤维呈降低—升高的趋势;总能(GE)和粗脂肪(EE)含量呈下降—升高—下降的趋势.抽穗期芦苇的DM含量、CP含量、NDF含量、Ca含量和P含量与生长后期无显著性差异(P>0.05),EE含量和GE含量与开花期无显著性差异(P>0.05),且达到最高水平.综合芦苇的营养价值和适口性等因素分析,抽穗期芦苇饲料化开发利用的潜力最大.
Study on the Changes of Nutrient Composition of Reeds in Tianjin Area
In order to investigate the changing patterns of nutrient composition of reeds in Tianjin and lay the foundation for reed fod-der utilization,the experiment collected reeds at different growth periods from major reed production areas in Tianjin and measured their conventional nutrient composition.The results showed that the crude protein(CP),crude ash,calcium(Ca),and phosphorus(P)contents of reed showed a decreasing trend from the leaf-spreading stage to the dead leaf stage;The dry matter(DM)and acid detergent lignin contents showed an increasing trend;The neutral detergent fiber(NDF)and acid detergent fiber showed a decreasing trend fol-lowed by an increasing trend;The total energy(GE)and crude fat(EE)contents showed a decreasing trend followed by an increasing trend followed by a decreasing trend.The DM,CP,NDF,Ca and P contents of the reed at the heading stage were not significantly differ-ent from those at the late growth stage(P>0.05),while the EE and GE contents were not significantly different from those at the flowering stage(P>0.05)and reached the highest level.The analysis of the nutritional value and palatability of reeds showed that the potential of reed fodder exploitation was the highest during the heading stage.
