Lactobacillus buchneri treatment enhances alfalfa silage aerobic stability and milk yield by 3.5%
Applying Lactobacillus buchneri to alfalfa silage significantly improves its resistance to spoilage when exposed to air and increases milk production in dairy cows.
Journal of Dairy Science · 2003
Key Findings
- 01L. buchneri treated silage showed increased concentrations of acetic acid and propionic acid after 56 days of ensiling.
- 02Treated silages resulted in greater dry matter recovery.
- 03Cows fed L. buchneri treated silage produced 0.8 kg more milk per day compared to those fed untreated silage.
- 04Total mixed rations containing treated alfalfa silage remained stable for 100 hours, while untreated silage rations spoiled after 68 hours.
Application
Design takeaway
Incorporate microbial inoculants like Lactobacillus buchneri into the silage production process to improve feed preservation and enhance animal product output.
How to apply
When developing or improving silage production systems, consider the inclusion of Lactobacillus buchneri as a treatment to enhance aerobic stability and potentially increase livestock productivity.
Project actions
- 01When researching feed preservation methods, consider the role of microbial additives.
- 02Investigate how different environmental conditions affect the efficacy of such treatments.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Inclusion of both laboratory and farm-scale trials provides robust evidence.
- +Directly links silage treatment to animal performance (milk yield).
Limitations
The specific strain of Lactobacillus buchneri used is important; results may vary with other strains. The study was conducted with alfalfa, and results might differ for other forage types.
Reliability & validity
The study's validity is supported by the use of controlled laboratory experiments and a feeding trial with dairy cows. Reliability is enhanced by analyzing multiple fermentation parameters and performance metrics over time.
Think critically
How might the increased acetic acid concentration, while beneficial for aerobic stability, affect the palatability or digestibility of the silage for different animal species?
Design Principles
"Optimizing biological processes through targeted microbial intervention can enhance material stability and performance."
This research demonstrates a practical method for extending the shelf-life of silage, a critical feedstuff in animal agriculture. By improving aerobic stability, it reduces waste and ensures a more consistent feed quality, directly impacting the economic viability of dairy operations.
What This Means for Your Design
Adding a special bacteria called Lactobacillus buchneri to alfalfa makes it last longer before it spoils and helps cows produce more milk.
How to use in your project
- 1.Reference this study when exploring methods to improve the shelf-life or nutritional value of stored organic materials.
- 2.Use findings on aerobic stability to justify design choices for packaging or storage solutions.

Paragraph starter
Research by Kung et al. (2003) demonstrated that treating alfalfa silage with Lactobacillus buchneri significantly enhanced its aerobic stability, extending its resistance to spoilage by over 30 hours when incorporated into a total mixed ration. This microbial intervention also led to a measurable increase in milk production in lactating dairy cows, highlighting the potential for biological treatments to improve the economic viability and efficiency of agricultural processes.
