Effect of Various Ratios of Complex Additives on Silage Quality of Fresh Corn Stover
The objective of the experiment was to investigate the impact of varying proportions of additive packages on fresh corn stover silage products.The experiment followed a completely randomized group design,with three treatment groups and three replicates each:a control group,test group 1(2%molasses+enzyme preparation of compound bacteria),and test group 2(4%molasses+enzyme preparation of compound bacteria).The fermentation quality of fresh corn stover silage was evaluated at 0,30,60,and 90 days.Samples were collected at 0,60,and 90 days to determine the nutrient composition of the silage.The results indicate that,ensilage for 30 days,both experimental groups had significantly lower pH values(P＜0.05)and significantly higher lactic acid and acetic acid contents(P＜0.05)compared to the control group.These findings suggest that both test groups improved the fermentation quality of fresh corn stover silage.
