天津地区芦苇营养成分变化规律研究
Study on the Changes of Nutrient Composition of Reeds in Tianjin Area
摘要
Abstract
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.关键词
