Effects of Different Dilage Fermentation Promoter and Silage Time on Quality of Wholeplant Corn

Abstract:

The effects of different silage fermentation promoter and silage time on quality of wholeplant corn in this study.Using local wholeplant corn as raw material,Cutting at the same growth period,Taking silage time and silage fermentation promoter as experimental factors,Field evaluation, nutrient analysis and silage quality test were carried out.The results:The sensory evaluation of the whole plant corn feed treated with different ensilage fermentation promoters was higher than that of the control group;The contents of DM, CP , ADF, NDF , ADL , ST , EE , WSG , TDN and CA in the whole plant after silage were significantly affected by fermentation promoters（P<0.05）;PH , lactic acid content, acetic acid content and ammonia nitrogen content in fermentation quality were significantly affected（P<0.05）;The silage time was better in Week 7 than in Week 9.Conclusion:The fermentation time of whole silage corn was 7th week (49 days).The quality of wholeplant silage corn was improved by using xianmu 1168 and new era silage, which was better than using no silage and other silage fermentation accelerators.
