过氧化氢和尿素对小麦秸秆体外发酵特性及甲烷产量的影响
Effect of adding perhydrol and urea on in vitro fermentation and methane production of wheat straw
摘要
Abstract
Objective]The aim was to improve the utilization efficiency of wheat straw in ruminant.[Methods]This stud-y was to investigate the effect of adding different levels of perhydrol (0,1%,2% and 3%)on nutrition value,in vitro fermentation and methane production of wheat straw ammoniated by 5% urea.[Results]Wheat straw treated with urea had a higher crude protein content compared to untreated group (P <0.05).Wheat straw treated with urea combination with perhydrol,the hemicellulose,cellulose and acid detergent lignin content were reduced with the increase of the per-hydrol level.When the level of perhydrol reached 3%,the hemicellulose,cellulose and acid detergent lignin content of wheat straw was significantly lower than that of untreated group and individual added urea group (P <0.05).All trea-ted groups had a higher (P <0.05)gas production compared with untreated group.However,methane production were no significant differences (P >0.05)among all treated or untreated wheat straw.Compared with untreated group and individual added urea group,the concentration of total volatile fatty acids was significantly increased (P <0.05 )when perhydrol addition level was above 2%.[Conclusion]In conclusion,it was suggested that optimum dose of perhydrol addition was 3% for wheat straw ammoniated with urea.关键词
