不同添加剂对全株大豆青贮品质的影响
Effects of different additives on silage quality of whole-plant soybean
摘要
Abstract
This study aimed to investigate the effects of different additives on the fermentation quality of whole-plant soybean silage.The study used different additives to treat whole-plant soybean for silage,with four groups set up,each having three replicates.The control group received no additives,while treatment 1,treatment 2,and treatment 3 groups were supplemented with 0.05 mL/kg lactic acid bacteria,0.10 mL/kg cellulase,and 0.10 mL/kg lactic acid bacteria mixture,respectively.The silage was fermented for 65 days.The results showed that the sensory scores of whole-plant of soybean silage in treatment groups ranged from 17.67 to 18.45,all higher than the control group,indicating high-quality silage.The color,odor,and total sensory scores of treatment 2 silage were significantly higher than those of the control group(P<0.05).The concentrations of nutrients and trace elements in silage in all treatment groups were not significantly different from those in control group(P>0.05).The ash-free undigested neutral detergent fiber content at 30 h(uNDF 30)in treatment 1 silage was significantly higher than other groups(P<0.05),while uNDF content at 120 h(uNDF 120)was significantly lower than treatment 3(P<0.05),and uNDF content at 240 h(uNDF 240)was significantly lower than the control and treatment 3 groups(P<0.05).The oleic acid(C18∶1)and linoleic acid(C18∶2)contents in treatment 1 silage were significantly lower than other groups(P<0.05),with total fatty acid(TFA)content significantly lower than the control group(P<0.05),but linolenic acid(C18∶3)content was significantly higher than other groups(P<0.05).The tannin content of whole soybean silage was extremely decreased(P<0.01),with reductions of 67.65%～80.15%across groups.Treatment 3 silage had the lowest tannin content(0.54 mg/g),significantly lower than the treatment 2 group(P<0.05).The study indicates that whole soybean silage added with cellulase has a better fermentation effect.关键词
