添加剂对紫花苜蓿和油菜秸秆混合青贮品质及维生素含量的影响
Effects of additives on quality and vitamin content of alfalfa and rape straw mixed silage
摘要
Abstract
To explore the effects of different additives on fermentation quality,nutrient quality and vitamin of mixed silage of alfalfa and rape straw,silage was made from a 5:5 mixture of alfalfa(Gannong 6)and locally harvested rapeseed straw at carob maturity.The experiment was set up with four groups of treatments:Control group CK(added distilled wa-ter);Enterococcus faecalis lactate Group Ⅰ(E.feecelis);Lactobacillus plantarum Group Ⅱ(L.piantarum);Enterococcus fae-calis lactate+Lactobacillus plantarum Group Ⅲ.After silage for 60 days,the nutritional quality,fermentation quality and vitamin content were determined.The results showed that the addition of different lactic acid bacteria additives could in-crease the content of lactic acid(LA)in silage and decrease the pH value,among which the treatment of Group Ⅱ had the lowest pH,which was significantly lower than that of Group Ⅰ and CK group(P<0.05),and the lowest ammoniacal nitro-gen/total nitrogen(NH3-N/Total nitrogen,NH3-N/TN),which was significantly lower than the control group(P<0.05).Wa-ter soluble carbohydrate content in Group Ⅱ was higher than that in other groups CK.The content of vitamin E in GroupⅢ was the highest.Group I had the highest vitamin C content.Grey correlation degree analysis showed that the compre-hensive performance of Group Ⅱ was the best.In conclusion,the fermentation quality of silage can be improved by add-ing lactic acid bacteria additives,among which Lactobacillus plantarum additive has the best comprehensive performance and is suitable for mixing alfalfa and rape straw silage.关键词
