摘要: 以校园鲜草苇状羊茅(Festuca arundinacea)新坪屑为原料,调制无添加或复合菌添加青贮,观察发酵品质,测定草坪屑产量和营养成分;并将干燥草坪屑粉碎后添加玉米粉等附加料,然后加工成草颗粒,测定饲料特性及干物质消化率,以探讨草坪屑的饲料特性。结果表明,草坪屑一年内可刈割5次,其鲜草及干草产量分别为13 269.3和4 120.7 kg·hm-2。草坪屑属易调制优质青贮原料, 添加复合菌剂能改善青贮的发酵品质;粉碎草坪屑单独或粉碎草坪屑中另加附加物均易制草颗粒,但是附加料添加能提高草颗粒干物质消化率,达到75%。草坪屑营养丰富,可用于调制优质青贮饲料、易制草粉和草颗粒等草产品,在生产中可用于优质饲草资源广泛开发利用。

Abstract: The grass yield and nutrient quality of Festuca arundinacea grass clippings after silage with or without additive or crushed and pellet with corn flower were analysis to investigate its feed potential. The fresh and dry yields of grass mowing 5 times per year were 13 269.3 and 4 120.7 kg·ha-1, respectively. Grass clippings were easy to ensilage whose quality could be improved by compound bacteria additives. Crush grass clippings individual or mixed with corn and other additives were easy to pellet whose digestibility of dry matter can be improved by additives to 75%. These results suggested that grass clippings had great potential to develop as a high quality forage resource.
