摘要
试验研究了不同浓度的甲酸(FA)、绿汁发酵液(PFJ)、甲酸+葡萄糖(FA+G)及绿汁发酵液+甲酸(PFJ+FA)四种处理对紫花苜蓿青贮品质的影响。结果表明各添加剂处理都显著降低了青贮料pH值和ADF含量,并提高了青贮料CP含量;添加剂处理能够明显改善紫花苜蓿发酵品质,提高青贮饲料饲用价值。综合感观评定、青贮料pH值和青贮料CP、ADF、NDF含量各项指标,FA+G(5.5ml/kgFA+1.0g/kgG)及PFJ+FA(2.5ml/kgPFJ+5.5ml/kgFA和5.0ml/kgPFJ+5.5ml/kgFA)处理效果最好。
The effect of Formic acid (FA), Previously fermented juice (PFJ), Formic acid+glucose (FA+G) and PFJ+FA on alfalfa silage was studied. Results showed that pH and ADF content of alfalfa silage was significantly declined with all the additives, and coarse protein content (CP) increased. It suggested that all the additives can improve the quality of alfalfa silage, and the treatments of FA+G (5.5ml/kg FA+1.0g/kg G) and PFJ+FA(2.5ml/kg PFJ+5.5 ml/kg FA, 5.0 ml/kg PFJ+5.5 ml/kg)had better effect on improving silage quality than other treatments.
