不同添加剂对苜蓿和小麦秸秆混合青贮品质的影响
The effect of different additives on the quality of mixed silage of alfalfa and wheat straw
摘要
Abstract
The objective of this study was to investigate the impact of various silage additives on the silage composed of a 6:4 ratio mixture of alfalfa(Medicago sativa L.)and wheat(Triticum aestivum L.)straw.The EF group received 1×106 CFU/g FM of Enterococcus faecalis(EF),while the LP group received the same concentration of Lactobacillus plantarum(LP).The LP+EF group was inoculated with a mixture of Lactobacillus plantarum and Enterococcus faecalis.A control group(CK)was established with the addition of distilled water and no bacterial agents.Following 60 days of fermentation,samples were collected for analysis of sensory attributes,nutritional composition,and fermentation characteristics of the silage feed.The experimental results demonstrated that additives could significantly enhance the quality of mixed silage composed of alfalfa and wheat straw.Specifically,the LP group exhibited the highest lactate content(6.57%DM)and crude protein content(19.83%DM),which were significantly greater than those of the CK group(P<0.05).The pH and acetic acid content of the LP group were significantly lower than those of the CK group(P<0.05).Furthermore,the incorporation of plant-based Lactobacillus plantarum notably decreased the levels of acidic detergent fiber,neutral detergent fiber,and the ammonia nitrogen-to-total nitrogen ratio in silage feed.This research indicates that the incorporation of Lactobacillus plantarum enhances both the nutritional content and silage quality of mixed silage feed composed of alfalfa and wheat straw,rendering it an optimal option for silage preparation.关键词
